Metro LX

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.
- Software audio through was not working properly in some cases where there was no audio data on the track.
- 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.

- 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.

- Some problems with subsections have been corrected.
- RNotes (Random Velocity Notes) are supported correctly in the new note edit dialog.
- Changing different plug-ins when in continuous efx automation views could fail to refresh properly in certain instances.
- 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 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: Groove Quantize to user defined grooves was not always working correctly.
- Fixed: Saving chord progressions was recently broken.
- Fixed: The cursor type was being erroneously reset when the cursor was over certain plug-in windows.
- Fixed: The input popup menu would erroneously popup in the remote control window after clicking in a different field in some rare instances.

- Fixed: The Intel version was not mixing or rendering 24 bit source audio data to 16 bit audio data correctly when the sample rates of the source and destination audio were the same.
- 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: An option to turn off the audio input source of an audio and MIDI track.
- 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.

- Fixed: Transport's float setting was not being saved properly in preferences and when in non-floating mode would activate inappropriately.
- Fixed: All notes would incorrectly be selected when the Graphic editor window was deactivated.

New: Metro no longer limits its compensation of plug-in latencies to audio packet sizes. Latency compensation is now sample accurate. However for technical reasons, Metro will still not compensate plug-in latencies on aux busses.

- New: A check is performed for audio input selections that out of range and a message is presented if this occurs. Previously an incorrect error message would occur after trying to record. The input select could become out of range if an audio port was changed.
- New: Support for AU's new metering parameter such as the one in Apple's peak limiter in Tiger (10.4).

- Fixed: A recent prerelease introduced a problem with USB audio devices such that audio recording would produce huge and incorrect latencies. This problem has been corrected.
- Fixed: a crash could occur when mixing or rendering a 24 bit source audio file to 16 bits and the sample rate was less than 64k.
- Fixed: A hang could occur if the user selected modify outputs and busses without stopping in certain rare circumstances.
- Fixed: Plug-in latencies were calculated incorrectly when more than one plug-in in a given plug-in chain reported latencies greater than zero.
- Fixed: The jukebox had a problem parsing artist names and album names from the directory path when the path was a volume (e.g. an audio CD).
- Fixed: If presets were mapped to programs for a given plug-in and program changes occurred within a track, the presets were selected at the wrong time when mixing/rendering.
- Fixed: In rare circumstances, software audio through was not always being enabled properly.
- Fixed: Parsing audio files by selecting a jukebox folder was not working properly when in certain cases.
- Fixed: Recording multiple MIDI tracks from different sources may not have been allocating the correct amount of memory.
- Fixed: If multiple MIDI tracks are record enabled and one is switched to audio some weird problems could occur.
- Fixed: When recording while synced to an external clock source the first few events were not always being recorded.
- Fixed: When waiting to record while synced to an external clock source the record button was not flashing appropriately.
- Fixed: special AUDIO + MIDI tracks were not recording audio.
- Fixed: Tempo changes were not always occurring properly the first time upon playback if there were audio tracks (or Soft-synths) and the sync was set to internal in the transport window. The easy work around, setting the sync to audio, is now uneccessary.

New to this version:
- New: All MIDI tracks can now be routed to accept input from a particular MIDI input controller (keyboard).
- New: Multi-MIDI thru allows all MIDI record-enabled tracks to be routed from their input to their output. Automatic MIDI thru must be enabled for this feature to take effect.

- Fixed: Soft-synth compatibility improvements including better support for when the Synful orchestra plug-in is placed on an aux buss.
- Fixed: Group Normalize was not working properly on 32 bit audio files.
- Fixed: Master volume automation was not being chased properly. This could result in the wrong volume being set for MIDI or soft synths if Master Volume Automation was in use.
- Fixed: Many improvements in regard to Quicktime Movie support including eliminating a potential crash when using undo.
- Fixed: Miscellaneous minor cosmetic issues.
- Fixed: Notes are no longer eaten during the end of count-off.

- New: It is now possible for the user to name audio input and output streams under OS X. This makes it possible to work around the fact that many audio drivers are not publishing names for the different streams of their devices. This makes it possible to have names like SPDIF-1 or ADat-2.
- New: A stop delay setting has been added to the device options dialog for Core Audio. This prevents glitching on stop for certain audio devices (e.g. Gina).
- New: The audio fade dialog box has been enhanced to include fade in and fade out buttons.
- New: Many more menu items are now available while playing. Selecting them, however, will cause playback to be temporarily halted.
- New: Jukebox now recalculates the bit-rate when the user gets info on the file.
- New: Jukebox now moves the currently playing item to the beginning of the file list when the shuffle button is checked.

- New: Subsection edits are now undoable.
- New: Instrument definition for the Korg Triton Extreme included.
- New: Minor audio optimizations.

- Fixed: A very serious bug involving sub-sections was introduced with multiple-undo. It could cause a crash when attempting to undo a subsection drag procedure. This has been corrected.
- Fixed: It was possible that a lengthy high-resolution MIDI file, when imported, would be incorrect due to integer math overflow. Such a MIDI file could easily be written by programs such as propellerhead's reason (Thank you Todd Rundgren for finding this).
- Fixed: It was impossible to record in stereo on certain audio devices that published multiple streams such as Echo's Gina.
- Fixed: Changing the output in real time now works correctly for audio outputs and aux sends.
- Fixed: Change ports was not changing the output's unique. This would cause Metro output ports, but not their names, to revert to old settings mysteriously.
- Fixed: The default core audio input and output device were not being restored properly when Metro was restarted if they were not the same device.
- Fixed: The factory setting Metronome was missing beats and behaving erratically in certain situations. Usually when the audio packet size was small. It was also not following the time signature and tempo changes if section events were set to loop.
- Fixed: When externally syncing the Metronome could tick once even though it was not on (this problem was introduced in 6.2.3).
- Fixed: There is no need to stop and resume playback after the jukebox output is selected any more.
- Fixed: Using the continuous data dialog on the Master fader only worked for 'Set to'. This has been corrected by completing the implementation.
- Fixed: The note display in the graphic editor was not being drawn behind EFX automation.
- Fixed: Double clicking in the tracks window would not always bring up the correct display in the graphic editor.
- Fixed: When audio outputs were dragged or pasted in the mixer window, the vu's would not be correctly reflected until playback was stopped and then resumed.
- Fixed: Enhanced AU plug-in support.
- Fixed: The preset popup item "Save AS" in the Effects window is now correctly grayed out if the plug-in has been specified as handling its own presets.
- Fixed: Scale time was not working properly on mixed audio and MIDI tracks. This could even have caused a crash when dragging bar lines.
- Fixed: It was possible to have the Metronome included when mixing audio. It was also possible that a count off would occur when mixing. Now the Metronome is always disabled when mixing.
- Fixed: Notation was unable to insert notes when an audio track was the only existing track.
- Fixed: Change ports also changes the default audio output. This helps the internal Metronome playback to make sound on the default audio device.
- Fixed: There was an incorrect latency calculation when recording using core-audio direct as the input selection.
- Fixed: Output vu's would on rare occasions stick.

New to this version:
- New: The Jukebox now supports playback of MP4 files, lossless audio and other variable bit rate (VBR) formats in OS X. This makes it even more convenient for using the Jukebox as a library for quick access to all your audio files.
- New: The Jukebox now support batch audio file conversion. Any quicktime supported audio format can be batch converted to either AIF, MP4, Apple Lossles, MP3 (with LAME component, available separately), WAV, MOV, and more. Simply shift or command-click to select multiple items and then ctrl (or right) click to select the batch conversion options.
- New: The controller popup of the graphics editor now contains an asterisk next to all controllers that exist within the current track. This makes it easier to find controller data.
- New: Better support for Audio devices stream names if the audio driver supplies them.
- New: If a core audio device returns an invalid stream while recording Metro now stops.
- New: Better copy and paste support for dual audio and MIDI tracks. It is now possible to copy and paste the current view without affecting the other view.
- New: Clicking on the search icon in the jukebox window now deletes the current search field.
- New: removed workaround for IK Multimedia's T-RackS because these plug-ins are fixed as of 1.2.1. Please update to version 1.2.1 of T-Racks if necessary.
- New: For insert or delete time, holding down the option key now forces the operation across all tracks. This makes it very easy to insert or delete time within the current sequence from the graphic editor.
- New: Better support for mixing audio with VST 2.0 plug-ins that watch if the transport is playing. This makes it possible to mix across the end of a track and have playing stop during mixing.
- New: Mix down audio now works across subsections.
- New: If enabled, a playbar is now drawn in each pane of the graphic editor.
- New: The shift-key will make all plug-ins shown in the graphic editor's plug-in popup.
- New: Repeating multi-part time signatures.

- Fixed: Wait 4 note recording mode now works properly for audio and soft-synths and if honoring core midi time stamps.
- Fixed: Apple's alias manager (under OS 10.3.x at least) sometimes does not find a file in the same directory that this file was opened from. Metro now does simple file searching before calling the alias manager.
- Fixed: Enhanced support for VST 2.0, including better compatibility with Sonic state's MicroTonic.
- Fixed: Several problems with notation have been corrected.
- Fixed: if a tempo change occurred at time 0:0:1, meaning there were duplicate tempo changes at that time, time was miscalculated. This would manifest itself as digital audio waveform overviews being incorrect or selections acting strangely.
- Fixed: a problem where continuous audio or effect automation would occassionally not insert maximum values.
- Fixed: double clicking in the tracks window would select a graphic editor view but that view was not always being remembered properly.
- Fixed: so that if sampletime != MaxSampleTime it is now honored and not re-discovered by looking into
- Fixed: the current play time is calculated properly when a new track is created in real time.
- Fixed: A possible crash when creating aux busses, if the port was set to off.
- Fixed: A problem where the jukebox scroll position was set wrong after filtering.
- Fixed: A problem causing deferred remote control events to record at a very wrong time!!!

- Fixed: a problem so that cutting a portion of a sequence with only one track does not cut sections events as well.
- Fixed: a problem with vu meters in the mixer window staying on after mixing audio.
- Fixed: Rendering audio does not remove MIDI data any more upon completion. This should be done manually to avoid doubling if the entire track is not rendered.
- Fixed: a problem whereby changing the graphic editor view from, for example notes to controller, would leave the notes selected.
- Fixed: Loop recording audio or soft synth tracks.
- Fixed: Better support for Audio Unit Music Effects.
- Fixed: A possible problem when asking for an audio directory.
- Fixed: Miscellaneous display problems.
- Fixed: Jukebox recent folder items were not being resolved properly in some cases.
- Fixed: Aux send automation was not displaying properly.

- New: 'wait for note' mode now works with audio and soft-synths.
- New: Optimization should improve drawing speed of audio overviews.
- New: Files dragged to the tracks window are now accepted.
- New: Plug-in editor windows are marked with their section and track location in the windows menu.
- New: Soft-synths installed after other soft-synths in an effect chain are now flagged and an error message appears.
- New: Metro now only saves program names to .ins files. The long standing reason why metro was not doing this was because there was no mechanism for storing sysex in .ins files. Sagan Technology has developed its own solution to this problem by adding a MIDI stream (MIDIS) command to the .ins file specification. We are hoping that Cakewalk with ratify this change soon.
- New: The plug-in popup, when selected on an aux buss, now shows all plug-ins not just soft-synths.
- New: The jukebox can now read iTunes information written into .aif files such as title, artist and more.
- New: Context-sensitive help can now be invoked using your local file system (OS X only). To do so you will need to download the Manual.sitx file from our web site. Unstuff it and place the resulant folder named 'Manual' in the Metro folder. Then from the help menu turn on 'local help'.
- New: Help tags can be turned off and on via the help menu.
