Metro

New to this version: 6.5.1

• Metro is now also a Windows 64 bit application. The 64 bit version was completely rewritten to not require QuickTime. It includes full mutli-core support and custom optimizations for SSE.
• Ripple editing is now supported with the use of the option key (alt key for windows). e.g. Cmd+Option+V will insert time before doing a paste for the length of the data on the clipboard. Alternatively you can hold the option key when selecting delete, cut or paste from the edit menu.
• Spray scale draw mode is a new mode of the spray paint tool which allows easy entry of riffs in a selected scale by simply clicking and dragging in the graphic editor. The duration can be changed on the fly and swing is fully supported.
• When entering numeric data in the graphic editor’s note edit dialog, floating point values are accepted in the bar, beat, duration bars and duration beats fields. e.g. you may enter 3.5 for the bar field to set the note to trigger in the middle of the third measure.
• The home, end, page up and page down keys are now supported in the plug-ins window.
• Metro SE users can now output audio in hundreds of additional formats using QuickTime.
• The port change dialog has a new checkbox ‘conform out of range audio outputs’ that, when unchecked, lets you retain your track input selections in case you have changed the output device temporarily.
• Woah is a new feature (similar to exposé) that allows all of the child windows to be visibly shrunken so that you can easily switch between windows. There is a new preference tab whereby you can select the options best for you. (windows only)
• Metro read and writes FLAC files. FLAC is a lossless compression audio file type. (windows only)
• The 32 bit version of Metro is now “Large Address” aware so it can allocate up to 3 (32 bit systems) or 4 GB (64 bit systems) of memory. For this to work on 32 bit operating systems you must enable the 3 GB switch. (windows only)
• Support for media keys, e.g. rewind, play/pause, skip forward, etc. (windows only)
• Many optimizations.

Fixed in this version:

• Loading a document with a missing plug-in will show the name of the missing plug-in, if possible.
• Initially upon recording, especially under the Lion OS, a long delay would occur.
• Many fixes and enhancements to the notation window.
• A crash could have occurred in the remote control window when selecting an input device.
• Independent track loops were not expanding correctly when expanding subsections.
• Swing is now ignored when quantizing tuplets/triplets.
• Improved VST support.
• In rare cases ‘expand by channel’ could have caused a crash.
• In rare case it was possible that a full sequence paste would not paste 100% correctly.
• It is now possible to move around project folders and have them still open without errors under windows.
• The duplicate command replaces instead of merging data.
• To conform to operating system standards, Metro will now auto-save the current Metro document when shutdown or logout is selected by the user. Upon re-launch Metro will ask if the user would like to reload the auto-saved document. (windows only)
• The set cue, restore cue and justification menu items were not doing anything. (windows only)
• In certain cases re-qualification was asked upon every launch of Metro. (windows only)
• Remote Control windows system exclusive dialog is now implemented. (windows only)
• Many other bug fixes.

Sagan Technology has announced the release of version 6.5.0.1 of Metro, the complete cross-platform digital audio workstation solution for both Windows and Mac users. Metro, Metro LX and Metro SE are available now directly from the Sagan Technology Store.

New to this version: 6.5.0.1

Support for documents with a very large amount of measures (Previous limit was 9999).

Record MIDI from VST plug-ins by selecting the input device from the tracks input device column popup. The plug-in must have 'record' enabled via the plug-in's contextual menu popup before it will show in the input device column popup. This makes recording from VST's more consistent with regular recording.

Support for documents with more the 4 billion samples.

In the graphic editor the cursor changes to show what will happen on a mouse click.

When an existing file is overwritten (via save) Metro now copies the old file to a temporary file named 'tmp.bysq' and then after the save is successfully completed, the temporary file is deleted. This makes it possible to recover any file in the case that some catastrophic hardware or software error occurs during a save.

Horizontal and vertical zoom in the graphic editor are saved and restored across application launches.

The notepad supports colored text. (Windows only)

Fixed in this version:

Metro now writes VST chunk data in one pass. This was causing a severe problem with certain NI plug-ins that change the length of their chunk data (seemingly randomly) over two consecutive calls. The problem could manifest in data file corruption or a crash.

In certain cases the transport window would now have the correct visibility when a document was opened.

Certain edits in the Effects window would cause the track to mysteriously change.

When loading plug-ins, audio output channels are verified and if necessary, conformed. Previously this minor problem could result in missing outputs in the output contextual menu.

Help tags were interfering with clicks in the Effects window if an effect had no editor.

Dragging notes in the graphic editor did not work properly if the switches menu 'Playback Scrolling' was set to 'All'.

Drag and drop is more accurate in its destination times especially when originating from the Jukebox window.

Dragging files from the jukebox now shows the file being dragged with transparency on the PC (already did so on Mac).

No checking for a new version is performed until the about box is manually shown and checking for a new version is selected in preferences. This works around a bug in certain versions of Quicktime that causes a crash when no internet connection was found.

Cueing past the end of an audio track would sometimes not playback properly.

Smoother audio playback on start and stop.

In rare instances Software Audio Through would inexplicably become disabled.

Weird problems would occur on playback if an old offline audio device was selected in an aux buss. Metro now displays an error.

Translucent dragging now supported under Windows XP.

For long sysex messages a progress dialog is presented (Windows only).

A crash could occur if the sections event windows was following play back and a different section than the currently playing section was selected.

Toggling the loop control in the sections event window would not reflect the loop in the graphic editor master view. (Mac Only)

The continuous audio data dialog now applies to the current selection. The values outside of the current selection are restored.

The continuous MIDI data dialog would only work correctly if the current controller was selected in the graphics editor window.

Slightly faster drawing of digital audio overviews.

It was difficult, if not impossible, to resize a very small digital audio region (one pixel) in the graphics editor by grabbing its resize handle.

It is now easier to select notes with very short durations.

It is now easier to click on the downward pointing triangle in the Effects window.

The pitch bend display of the graphic editor was not working properly in all cases. (Windows only)

Define silence (from the audio menu) was completely broken. (Windows only)

Set and Restore Cue menu items were completely broken. (Windows only)

Improved mouse wheel support. (Windows only)

More 'quality presets' in the MP3 tab of the preferences dialog. (Windows only)

Workaround a Windows 7 bug whereby upon selecting a folder the default would be out of view.

Dragging of bar lines was difficult if edit quantizing was enabled.

Opening an old Metro document no longer sets the columns in the track window incorrectly in certain cases.

Real-time editing when a subsection was selected could cause problems.

Undo was was resetting the selected tracks incorrectly in certain cases.

Workaround a problem in Vember Audio's Surge plug-in that causes the menu bar to become inaccessible. (Mac only)

Re-scanning plug-ins from the plug-ins window with no plug-ins failed.

A number of minor miscellaneous bug fixes

New to this version: 6.5
• First windows version with standard music notation and printing.
• Notation sizing option allows notation to be bigger or smaller.
• Drum symbols can be specified for standard music notation drum tracks.
• Real-time dragging gives you what you see is what you get (and what you hear) in real time while dragging. No more grey outlines for most dragging operations including standard music notation.
• Spray can tool has been signigicantly enhanced to include the scale spray and the phrase paste feature. The scale spray feature allows the user to draw and drag scales in real-time with the duration specified optionally by the end of the drag (fit to drag) or by the graphic editor step duration. The phrase paste feature allows the user to drag and draw copies of the clipboard, multiple times, transposed by the cursors y position. Double click the spray paint tool to set spray paint tool options.
• Keyboard window's real-time arpeggiator has many new features, including:
• Patterns up to 32 steps
• A new row for specifying the note index combination (chords). Any combination of notes of the first 7 notes being played can be specified in each step of the arpeggiator.
• Better display of rests.
• MIDI learn (right-click) for "arpeggiator on" and "pattern select" functions.
• Record generated notes only option for recording MIDI data that is generated by plug-ins only. This option is accessed from the effects window by right-clicking on an instantiated plug-in that is able to output MIDI.
• Global highlight color specified in preferences is saved and restored with the Metro document.
• Plug-ins window support sub-sorting so that if the user changes the sort column, the previous sort column becomes the secondary sort criteria.
• Plug-ins window has an option for re-scanning plug-ins. This function forces the user to save or discard the current document before it rescans. Useful if you were already running Metro when a new plug-in is installed or, under windows, if you change the default plug-in location from preferences.
• Clicking on the support or sales email address in the about dialog brings up the default email program.
• A warning message shows in the graphic editor when software audio through feedback protection is activated.
• Improved cross platform document transportability.
• Outputs added to the graphic editor track titlebar's contextual menu for Aux buss and Master views.
• In the graphic editor Master view, Add Fadeout Automation, added to contextual menu for quickly adding a fadeout to all tracks.
• User specifiable VST plug-in parameter ranges by clicking on the ranges in the graphic editor. These ranges are maintained for each plug-in. (Not supported on PPC computers).
• The demo version will print one page of notation with a water mark.



Fixed in this version:
• Better automatic notation and many fixes to the notation engine.
• A looped audio track cued beyond the end may not have cued properly.
• In some cases the Render function of Mix or Render Tracks would not render the first audio buffer.
• It was possible to view aux send volume and aux send pan even if there were no aux busses.
• Some audio settings were not being restored properly. (Windows only).
• Audio waveform data out of range could cause graphic anomalies in the graphic editor. Other minor cosmetic changes to the waveform display.
• USB drives can be ejected directly after a file is saved to it. (Windows only)
• Help tags were leaking graphic objects. (Windows only)
• Clicking on the search triangle (plug-ins or jukebox windows) clears the current search criteria. (Windows only)
• Resizing the jukebox could cause the buttons to wander. (Windows only)
• Popup buttons in the jukebox window popup and on the first click. (Windows only)
• Right-clicking the sections windows title bar causes a menu to popup which allows you to open the path to the Metro document in explorer. (Windows only)
• An error message will now popup if the number of graphic objects are leaking to give the user a chance to save before windows screws up the display. If this problem occurs it almost certainly indicates a bug in a plug-in as Metro makes every conceivable effort to avoid this problem. (Windows only)
• Long sysex messages would not always be sent properly. (Windows only)
• A crash could have occurred when moving the cursor to the event editor. (Windows only)
• A crash could have occurred if a very long file name was encountered while scanning for plug-ins. (Windows only)
• Duplicate file names could creep into the recent files menu. (Windows only)
• Improved multi-monitor support. (Windows only)
• Support for the keystroke remote control command. (Windows only)
• In rare cases it was impossible to switch out of SMPTE Display or Bar Display mode from the switches menu.
• Metro was not honoring if a new version of a plug-in changed its editors window size, usually causing truncation.
• The audio setup dialog comes up automatically if no audio devices are specified at startup.
• The current duration is restored properly even if the parts per quarter note has been changed.
• Rhythm Explorer will no longer auto revert the current track just because the selection has changed.
• Track and selection properly restored after an undo of the Harmony function.
• Notation window could lose its status bar and/or tool bar after resizing.
• Metro will now always change the track duration after the insert time or delete time function are performed.
• Duplicate aux buss names could have resulted from a paste operation.
• The waveform icon in the graphics editor that appeared only when an audio track was active has been removed since it was inconsistent to have that option be selectable only for audio when it also affects the way MIDI is edited. It remains in the switches menu as Region Editing.
• Improved paging support for popup menus with massive numbers of items.
• Groove quantize failed if the PPQ (parts per quarter note) was changed.
• If an input audio port was out of range and there were no audio inputs an out of range error dialog would pop up. Now it is simply ignored.
• Switching a tracks output from soft synth (vsti) to MIDI or visa versa could have affected the timing of that track.
• Holding down the control key causes Metro to not check for new versions when the about box is displayed. In certain versions of Quicktime, when no internet connection is active, this could have caused a crash. Usually on startup.
• Slightly less sensitive software audio through feedback protection.
• Adding/subtracting values in the continuous data dialog to audio volume works more consistently.
• A crash could have occurred when changing audio devices (Windows only).
• In some rare cases it was possible that the Metronome would not function.
• A compiler bug was causing Chord Progression insertion to fail (Mac only).
• Dragging all tracks in the tracks window down and to the right could have caused a crash or other problems and was not undoable.
• Canceling out of the mix or render dialog could have brought up an erroneous error message.
• It was possible that audio recording could end prematurely.
• Several other fixes and feature and performance enhancements.

New to this version: 6.4.9.2

New to this version: 6.4 (over 50 new features!)
- Mastering. A chain of plug-ins can now be placed on the master causing all tracks and aux busses to process through the chain before being sent to the final stereo output. In the full version of Metro there is now a Master track selection from the tracks popup. The master track has a settable duration, can be looped and can be muted. Muting the master track causes the effects chain to be bypasses which can be useful if you want to addition a recently rendered mix to a track. If an effect is placed on the master buss, the master VU now displays the actual audio signal level instead of simulated audio+MIDI level.
- Side Chains. Metro will now send track audio output or aux buss output to multiple plug-in inputs. Plug-in inputs can be specified by control-clicking the title bar in the effects window and specifying the appropriate source audio. If post is selected the data will be send to the plug-in post fader otherwise it will be pre-fader. For aux buss sources the source is pre-fader only if the aux is feeding data to a lowered number aux buss otherwise it is post fader.
- The number of plug-in's audio inputs can be selected in the effects window (AU only).
- Aux busses can be looped, have a settable duration and can be muted in the graphics editor (full version only). Muting an aux buss will mute the effects chain on that buss.
- The last selected audio sample rate and sample bit size is now saved and restored with the audio device.
- Real-time display of MIDI notes while recording. Since the data is immediately moved directly to the track this feature results in an improved loop recording experience as well.

- Effects window GUI rack is complete with new 'Del' (delete) buttons. This new GUI is switchable and can be turned off from the effects window contextual menu popup.
- Effect window plug-ins rack color can be specified by control-clicking the name in the effects window. Colors default to the corresponding specified category in the plug-ins window.
- Effects window contextual menu item 'show in plug-ins' finds the currently instantiated plug-in in the plug-ins window.

- On older systems it was possible that the G4 vector unit would not be recognized causing Metro to quit even though it was running on a G4.
- Pressing the 'esc' key while Metro is loading causes it to stop searching for plug-ins. Previous to this version it would also permanently remove items from the Graphic Editor's plug-ins menu.
- Better ReWire error messages.
- Since 6356 certain windows would not be deactivated properly.
- The cursor changes more appropriately in the drum editors.
- Miscellaneous cosmetic improvements.
- Dragging at the sample level has been improved.

- A crash could occur when loading a plug-in with an odd number of outputs (> 1) on a track.
- Metro no longer sends the selected bank select message more than once when looping.
- The Ultra Rhythm Explorer Phrase Arpeggiator algorithm has been substantially improved.
- The find program dialog has been improved.
- When attempting to apply an offline effect on an Audio + MIDI track, Metro would erroneously report that no audio tracks were selected.

New: Multiple outs for track insert plug-ins. This makes it possible to assign multiple mixer channels to a single plug-in. Documentation on this new feature will be posted soon.

- New: Automation only tracks. This track type will affect the volume and pan of a sound generating track if it is assigned the same Metro output as the sound generating track (or multi-out) and the sound generating track has no automation of its own. Automation tracks can have independent track lengths and loop settings.
- New: Sample accurate automation for AudioUnits (AU) if the AU plug-in permits.
- New: Miscellaneous optimizations.
- New: Software Audio Thru now works for 1/2 duplex audio devices. A 1/2 duplex audio device is one, such as some USB audio devices, that has un-synchronized input and output.
- New: The last selected controller or automation parameter is correctly remembered for each track.
- New: The Intel version (not LX or SE) now uses Intel's SSE vector processor to optimize Metro's performance.
- New: When zoomed into the sample level it is now possible to right click on the sample to edit the sample numerically. It is also possible to edit 32 bit floating point sample data now.
- New: A popup in the Metronome dialog now allows the user to route the Metronome sound to a particular Metro output.
- New: Clicking on the output dots in the effects window (after the plug-in name) brings up a popup allowing the user to configure AU plug-ins number of outputs.

Fixed in this version:
- The Metronome has been updated to version 1.0.3. There was a problem when counting off with certain plug-ins loaded where the Metronome would produce noise during the count off.
- Zipper noise when moving Mixer faders.
- Muting or soloing a track insert soft-synthesizer now works as expected. Previously certain plug-ins would produce sound even when muted in case other tracks were sending MIDI to the plug-in.
- If a realtime edit was performed while looping over the end of a track the playback bar could possibly be positioned incorrectly.
- When cueing, automation starts at the right sample number.
- The mixer's mute status was not being honored in certain cases.
- Was crashing on initial paste of continuous data into blank audio track.
- Effect automation data display in the graphic editor was sometimes displaying values out of range.
- Changing audio devices would sometimes leave the default audio device as invalid.
- Some error messages have improved.
- Better support for aggregate devices.
- Crash could occur when using the offline effects processor on 32 bit audio tracks.
- When creating drum sets on the fly it was possible that the custom drum name entered would be ignored.
- AU timing accuracy as reported to the plug-in is improved especially when count-off is enabled.
- Was leaking memory for certain AU plug-ins.
- Workaround for Intel Macintosh Apple OS bug where the cursor position is off by one pixel.
- The internal version number was not being calculated correctly on Intel Macs. This could allow newer versions of Metro documents to attempted to be read instead of an error message presented. Caution should be used to not open newer documents when using previous versions of Metro on intel Macs.
- Better defaults in the Modify outputs and busses dialog.
- Selecting a folder in the jukebox during playback no longer messes up the play back position display of audio tracks.
- Clearing velocity data when no MIDI data exists on a track no longer results in a crash.
- Copying automation data was not possible from the graphic editor when a Software Instrument was selected in certain cases.
- When pasting and the clipboard contents contain a track insert Software Instrument, the Software Instrument will be restored only if the destination track has no MIDI data.
- It is now possible to paste automation data on to a completely empty track.
- MIDI files are now written correctly on Intel Macs. Please delete any MIDI files written by Metro prior to this version on Intel Macs as they were invalid.
- The Normalize output faders feature has been improved.
- When closing a pane in the graphic editor, it was possible that the other views could change improperly.
- Was possibly drawing the wrong data if two MIDI controller views were active in the graphic editor.
- Stop was flashing in the Transport when audio device was changed in certain cases.
- VU's in the mixer window would get stuck in certain rare cases.
- The Input and Output contextual menu popups are improved.
- Changing the Transport window's floating state would sometimes change the size of the Transport window and would also prevent help tags from working.

New to this version: 6.3.5.6
- New: Normalize Faders function in the special menu. This function mixes audio for all track for the current selection and based on the resultant peak sets the mixer faders so that the mix does not clip in most cases.
- New: View plug-ins by manufacturer or category. View all and view recently instantiated plug-ins. All this functionality in a simple menu and submenu interface directly from the graphic editor.
- New: Metro will interpret the enclosing folder name of any (Mach-O) VST plug-ins as the manufacturer name.
- New: When "manufacturer" is the selected plug-in sort field Metro will sort plug-ins by name if the manufacturer names are equal.

Fixes in this version:
- On Intel Macs, strange errors or crashes could occur after opening a Metro document saved prior to version 6.2 that contains audio.
- Intel Mac could crash after cueing an empty audio track.
- Intel Mac could crash after clearing an audio track while playing.
- Turning the power off in the effects window did not work consistently.

- Certain Virtual Instruments (VI) would become quiet if a Metro output was reassigned during playback.
- A problem with pitch-preserving fast forward on multi-output audio devices was corrected.
- If a core audio aggregate device was created and named 'built-in' a problem could result with subsequent recording.
- Using an arrow on a note of Bb in the key of Ab minor would stick at Bb, instead of going to Cb.
- Dragging a sample, when zoomed all the way in the graphic editor, now displays the sample value in the upper left.
- After saving a .ins file the currently selected bank name is no longer replaced with the name of the .ins file.
- Trim outputs was not preserving audio outputs that were the destinations for Virtual Instruments.
- In certain cases the availability status of menus were not being set properly.
- A new fatal error message was added if the user attempts to run a version of Metro that requires a G4 processor on a G3 or earlier processor.
- A possible crash could result if the jukebox was empty and remote control was active.
- The jukebox slider now indicates the time within the currently playing song as it is dragged.
- Typing the name of the song in a long list of jukebox entries now works more reliably.

- Mixing down to 24 bits on an Intel Mac could create pops and clicks in certain scenarios.
- Pasting note data or adding data to a VI track while cueing would not set the playback position for that track correctly.
- Port change dialog no longer defaults the destination to a non existent core-audio port.
- Better enabling and disabling of menus when the offline effects or progress dialogs are in front.
- A problem whereby making changes to section events could affect track effect automation data detrimentally.
- It was possible that a newly opened Metro document set to show effects automation using a AudioUnit plug-in would not initially show the correct information because the scale of the displayed parameter can not be determined until after the plug-in is loaded.
- Dragging files into the tracks window would occasionally leave ugly blue lines.
- Expand By Drum was not setting the correct resultant track type to MIDI.

A crash could occur when selecting a Metro output of a non-selected track in the tracks window.

- VST plug-in editor windows would come up blank on the second edit.
- New output is now always created when loading a soft-synth as a track insert.
- Master fader VU is no longer updated for softsynths since the audio level of the softsynth is king.
- Possible crash when stopping playback while direct-recording with software audio thru on.
- Possible crash when expanding subsections with a frozen audio track contained in the subsection.
- Program names loaded from the program names dialog on soft-synths ports were not being remembered correctly since Metro version 6.3.3.
- The Jukebox was creating an internal error if certain OS errors occurred.
- The Subsection edit dialog did not refresh the color swatch after it was changed.
- New plug-in option for plug-ins that cannot be re-initialized (USB:Ultrafocus). Accessed, as usual, by a right-click or control-click on the plug-in in the plug-in's window.

New to this version: 6.3.5.2

- New: A menu item 'Automation Record' has been added to the switches menu. With its corresponding key combination, the user can now invoke automation recording much more easily.
- New: An item has been added to the Effects window output selection popup to allow for a new audio output to be created.
- New: The qualification dialog has been rewritten to take advantage of OS X features.
- New: The Note edit dialog (control-click a note event in graphic editor window) and the program change dialog have been updated to take advantage of OS X features and are now movable.
- New: The pitch corresponding to the cursor position displayed in the graphic editor is now based on which slot the cursor is in.
- New: More robust automatic bank and program matching when a MIDI file is imported. Previously Metro would automatically match a bank selection only if both the LSB and MSB of the bank select (MIDI controller 0 and 32) were present and sequenced directly after one another. This restriction has been lifted.
- New: Automation has been improved for AudioUnits. This include new support for the "Gesture Type" callbacks in OS X 10.3 or greater.
- New: Optimizations for AU plug-ins provides better support for plug-ins like Ultimate Sound Bank's Ultra Focus.

- Fixed: A crash could occur if multiple sections were cleared during playback.
- Fixed: A crash could occur when trying to transpose, time stretch, or apply an effect to an archived audio track.

- Fixed: A crash when selecting the clef in the notation track setup dialog.
- Fixed: A problem caused the selection of certain popup menus within plug-ins (e.g. FabFilter Twin) to be ignored.
- Fixed: The master VU was not showing activity for MIDI data if the individual MIDI data VU's were not visible.
- Fixed: The implementation from 6.3.5 of having the Master Fader not affect softsynth MIDI faders was not completed properly. This would result in MIDI softsynth levels (controller 7) being erroneously sent to the softsynth plug-ins in certain circumstances.
- Fixed: Scale Time would occasionally set the tracks length incorrectly.
- Fixed: Clicking on a plug-in in the plug-ins window was not working in some rare instances.
- Fixed: When mixing or rendering to 24 bit audio data, the last sample was garbage and could cause a glitch at the end of the audio.
- Fixed: It was possible in some rare cases that edits made to effects automation would not show up unless there was MIDI or audio data on the track first.
- Fixed: If a Graphic editor slot was zoomed out and the track contained in that slot was selected from the tracks window it would not show up. This has been corrected. Now when the track is selected the zoomed in slot is zoomed out first and then the new track's slot is zoomed in.
- Fixed: It was possible that menus were erroneously being enabled when in certain modal dialogs.
- Fixed: Mighty mouse support was not working when the graphic editor was zoomed in to an audio sample level.

- Fixed: Dragging an item in the jukebox would sometimes change the selected file to be played incorrectly.
- Fixed: Some miscellaneous problems with reassigning soft-synth tracks to audio and visa versa has been corrected.
- Fixed: A problem whereby if "Paste And..." was previously performed, the Rhythm Explorer would not function correctly.
- Fixed: Double clicking in the tracks window erroneously did nothing in certain circumstances.
- Fixed: A problem whereby the notation was not being completed disposed of upon exit. This could leave orphaned printer description files in the directory /private/var/tmp.

New to this version: 6.3.5
- New: Full Mac Intel processor support.
- New: Mighty mouse support allows horizontal scrolling with the mouse wheel.
- New: Vastly improved remote-control event support. Support for RC output events. A preset fully supporting Frontier Design's Tranzport included.

- New: A new option added to the output assign menu allows a new Metro output to be created before being assigned to a track.
- New: Dragging the tempo ruler in the transports rounds the BPM to a whole number.
- New: The return and fast forward buttons in the transport now move all edit windows when not playing.
- New: Trim outputs to tracks menu item. This option rearranges in section, track order and also removes all unused outputs from the Metro document.
- New: Option for sending tempo changes to plug-ins early. This makes it possible for AudioUnit plug-ins like Stylus RMX to work correctly with multiple tempo changes. This is selectable for each plug-in by right-clicking or ctrl-clicking on the plug-in in the plug-ins window.

- Fixed: A possible crash could have occurred when closing one of the program names dialogs.
- Fixed: A possible crash could have occurred when clearing a plug-in.
- Fixed: Softsynth outputs MIDI volumes are now correctly unaffected by changes to master volume. In previous versions the MIDI and audio volume of softsynths were both being changed when the master volume was changed.

New: Support for format converter Audio Units. This is a special kind of AudioUnit whereby the amount of input audio data is not always equal to the amount of output audio data. In OS 10.4 (a.k.a. Tiger) Apple released an incredible Time/Pitch stretching audio unit that is completely supported. This AudioUnit, when available, is now used as the default for Metro's time stretching and transposition of audio. It can also be used for audio scrubbing as noted below.

- New: Audio Scrubbing under OS X is now functional. There are 3 types of scrubbing. With the mouse down in the audio area of the graphic editor and scrubbing enabled in the switches menu, the scrub mode can be selected with the following keys:
'A' - Normal Scrub. 'S'- Unity Scrub, this limits the playback speed to a maximum rate of normal allowing playback forward and reverse to follow the cursor. Option - Shuttle Scrub.
- New: The continuous data dialog now allows exact ranges of floating point values to be entered depending on the selected parameter. For AudioUnit and VST automation this makes it possible to set exact values.
- New: Locking fast forward, no pitch change fast forward (under Tiger only) and other options. Control-click the fast forward button for options. The setting here affects audio scrubbing as well.
- New: Minor cosmetic changes to the graphic editor audio display.
- New: Audio regions can have names and those names are now displayed in the graphic editor. To edit them, double click on the audio region.
- New: the meaning of bypassing a MIDI soft synth effect has changed so that the audio is bypassed and so are the
MIDI notes but program changes and other non-sounding events are passed through. Previously all events were filtered while bypass was enabled.
- New: This is the first version of Metro that uses Carbon Events. This should result in performance improvements.
- New: The graphic editor, tracks window and event list editor displays are updated quicker upon opening a Metro document.
- New: It is now possible to drag files from the jukebox or the plug-ins window without bringing the window to the front.
- New: Zooming in the graphic editor is improved as discussed in the Metro feature request forum.
- New: The cursor changes to a hand when in audio region editing mode in the graphic editor and a resize cursor when over the region drag handles.
- New: The offline plug-in menu is now sorted by the last sorted method in the plug-ins window.
- New: Dragging sections in the sections window will not save the sections to the undo history if the command key is held down. For huge files this could be very slow while it devours all of available memory.
- New: Double clicking on a pan knob or a volume slider in the mixer window returns it to its default value.
- New: Note pad actions are now totally undoable including typing, clearing, cutting and pasting.
- New: Changing the setting 'Plug in Manages Presets' in the plug-ins window now deletes all current presets until the plug-in is reinstantiated.

Many fixes and other overall stability and cosmetic improvements. For complete details see here.
