MU.LAB

Highlights

Reworked MUX front panel construction system.
Front panel components can now be layered and moved together and many more supported component types. The MUX front panels are the bridge between MUX' deep modular world and the effective use of synth and effect presets while creating music.

Tracks can now have individual heights.
Different track heights are also preserved while zooming in and out or calling vertical overview.

Collapsed sub-tracks are always shown, be it very minimal.
This avoids confusing situations that could occur with the previous behaviour of fully hidden sub-tracks.

New Oscilloscope module. The oscilloscope also includes a sync mode which allows to display dynamic synth waveforms. Also works for VST plug-ins.

Added an extra mode to the Audio Limiter module: Now it can work in Hard Mode and Soft Mode.
Previous versions always worked in Hard Mode which in the end really clips the audio. In Soft Mode the audio level is limited more in a soft way so that even for high audio levels there still is a difference in output level. In other words there always is some degree of dynamism preserved. This is more suited for general mixing use. The Audio Limiter now also has an Input Gain parameter and input and output level meters.

Improved MuDrum layout: Element 3 has been minimized so it only contains a display where you can choose the extra plug-in module for this drum pad. This results in a more simple and comfortable layout where the two sampler displays have more space now. Another advantage is that you can now directly use an extra VST plug-in layer for this drum pad without having to go via a MUX Modular.

The TanH Distortion module has been expanded to a much more flexible "Amp. Distortion" module.
It now includes a customizable curve display, which also makes it visually more clear how the distortion works.

New Piano Keyboard, Note Event Pad and Audio Level Meter modules.

VST editors now can have a focused parameter editor in their top control bar. This focused parameter editor is a handy bridge between any VST parameter and the MuLab / MUX user interface. Right-click the parameter for handy functions like Copy As Parameter Event or Copy As Envelope Point. You can easily create automation tracks for VST parameters by drag-dropping this focused parameter editor onto the [+] track button. It can also be used to monitor the value of VST parameters for VST's that don't show this in their editor. It can also be used to copy-paste VST parameter values even in VST editors that don't support such functionality. And more.

You can now drag-drop a parameter on an automation envelope editor, this will create a new point with the parameter value. Also works with the new focused VST parameter editor.

Added 3 extra fine grids: 1/256th, 1/512th, 1/1024th to support high precision editing.

MuLab Free: Empty tracks or pure automation tracks are not counted as track anymore.
So you can do a lot more in free mode without encountering a switch to demo mode.

More than 90 other important improvements, see details below.

Improved

Virtual Keyboard now has an Octave Shift which can also be tweaked using the Page Up and Page Down keys.
Scanning VST plug-ins: Now an explicit diagnostic message is given when there is a 32 bit 64 bit mismatch.

MUX VST: Improved propagation of the audio input and output names towards the host.
MUX VST: Support for defining the number stereo ins/outs.
First metronome beat is louder than the others.
LFO: When in tempo-sync mode, you can also input the frequency parameter as "1/4", "3/8" etc.
New "Delete Unused Racks" function. Via right-click the [+] rack button.
Drag-drop an audio stream or sample object on the [+] track button creates a new track.
Pure Delay now also supports stereo mode.
Improved handling of pitchbend events resulting in several advantages:
Pitchbend events now properly travel thru a rack, no blocking at the pre/post point anymore.
You can use pitchbend as a controller to a parameter and meanwhile also use it to keep on controlling pitch bend, if you want.
In case the focused VST parameter editor is off, VST editors now have a "Edit Last Tweaked Parameter" context function which pops up a temporary focused VST parameter editor, so al of its functionality can always be accessed, even when it is prefered not to have it up front.
Envelope points now also have Copy/Paste Value context functions.
Parameter editors now have a "Copy As Envelope Point" function.
Copy-pasting parameter and envelope point values are more compatible and support both normalized float values and percent values.
Parameter controls: When the parameter name is too long to be displayed, then the full name now is shown in the tool tip.
Added protection against inputting invalid parameter values via the parameter's input dialog.
Finetuned the automatic MIDI input focus behavior when activating module editors. (more relaxed behavior = less changes)
Modular area: when (re)connecting jacks, the tool tip could be in the way which canceled the drop. Fixed.
Browser -> MUX Presets -> Refresh List does not ask "Also refresh MUX preset cache data?" anymore, it will always do so.
Event graph editor: When changing multiple selected velocity bars, and they all have the same velocity, no more popup question "Change Absolute/Relative/..." anymore as it doesn't make sense in that case.
Note To Modulation Converter now has a Low and High Key which define the note key range. Notes lower than low key will generate the minimum value, notes higher than high key will generate the maximum value. If you don't want that notes outside the defined key range cause a modulation value update, insert a Note Filter before the Note To Modulation Converter.
Event Graph Editor: Line edits are now end point inclusive. And ensured that when drawing pitchbend/controller/parameter event curves that the end value is exactly as intended.
Event Graph Editor: When clicking a velocity beam while holding Ctrl, this will now do the value line.
Drum Note Processor editor window now is resizable.
Finetuned behavior wrt parameter automation parts when positioning the play cursor in a composition.
Improved defining the target module for recording the MuDrum pads and Drum Note Processor pads.
Constant Modulator module: Value parameter automations now are smoothed to avoid zipper noise.

Improved MIDI Sync: Upon looping a relevant MIDI Song Pos event is sent out.
Improved stepping the play cursor forward in a composition with an active loop.
The intensity of the panel surface texture now is a preference.Setting it to 0 results in pure clean panels, setting it to eg. 12 adds a bit of vintagy to the panel looks.
Event Graph Editor and Envelope Editor: In case of bipolar curves/envelopes, there now is improved behavior wrt the middle zero line.
Modular Editor: While holding [Shift] clicking the background does not clear the selection anymore. This makes it easier to multi-select cables.
Modular editor: Right-click module jack now only pops up context menu when relevant.
MUX Modular: In and out jacks now have same name as the respective in and out modules in the modular editor of that MUX.
Finetuned display position of the window title text, avoiding the text to go under the window buttons. Especially relevant on OSX where the title text is centered.
Finetuned the dialog for the "Sequence -> Change ..." functions: The buttons are replaced by a tree list.
Soloing a rack also takes any racks into account that are sending/outputting to that rack. This is important wrt the use of racks as busses.
Improved previewing strategy: If you add a mixer strip or rack in the Project Modular Area and name it "Preview Monitor" then all previewing is routed thru that mixer strip or rack, and so you can finetune the level there.
Changed the "Quantize 50%" function to "Quantize N%" which uses a popup dialog where you can enter the percent value.
Multi-Wave Oscillator: New "Multi-Waveform CPU-RAM Usage" preference which allows you to better balance between CPU and RAM usage.
Added a "Choose From Library" function in the waveform context menu.
When choosing a waveform from the library list, the current waveform is highlighted.
VST editors: MuLab now gives keyboard focus to the VST child window.
MUX Modular VST: Clicking in the main MUX VST editor window makes it grab the keyboard focus.

The "Show Preview Monitor" function now automatically creates a new "Preview Monitor" rack if necessary.
Added protection against inputting invalid parameter values via the parameter's input dialog.
Improved stepping forward the play cursor in a composition with an active loop.
Multi-Point Envelope editor window now is resizable, and can be zoomed in more so to comfortably make very precise edits.
Added "Show Preset File Path" function to the Presets function group.
MuSynth, MuDrum and MultiSampla effect slots now have edit and options buttons at the right.
Optimized the horizontal overview function for envelopes. (previously the result could be much too wide in case of short envelopes)
MuDrum and Drum Note Processor: The pads now also light up when playing very short notes.
More efficient animation of the MuDrum pads, generally resulting in a more snappy UI, especially on slower systems or upon high CPU usage.
VST plug-in -> Show Info function now shows more detailed VST specific info. This extended info is also included when doing "Export Consolidated Project".
Export consolidated session: VST plug-in list: VST plug-ins that are used multiple times are only listed once now.
Improved a sonic aspect in the MultiMode and TF Lowpass filters wrt cutoff frequency and key tracking so to ensure that even low keys get the highest possible cutoff frequency.
Several detailed improvements wrt importing/exporting MIDI files.
More relaxed auto-delete for unused sequences and samples. (less auto-deletes)
Finetuned positioning of popup edits, eg. browser -> rename file, but also several others.
Added more editable skin colors.
Improved color picker.

Sequence functions: Quantize, Quantize 50% and Quantize Lengths all take the sequence start locator into account wrt defining the grid.
Sequence editor: When targetting a rack with a synth module that is using note key names, the mouse cursor info display was not showing the key names. Fixed.
Sequence editor: When targetting a rack with a synth module that is using note key names, choosing a mask for the Event Graph Editor didn't show the key names. Fixed.
LFO: Loading projects/presets made with versions prior to M6.4 now properly defaults the new End Fade parameter to the same value as the Start Fade parameter for sound compatibility.
Fixed a sonic bug when changing synth parameters while no notes where playing, then a little quick fade from the previous value to the new value could be heard. Fixed.

Highlights

Greatly improved LFO module:
All LFO shapes are fully editable now.
LFO shapes can be saved/retrieved using MuWaveShape preset files.
LFO now has a Start Phase parameter, which can also be set to Random.
LFO now both has Start Fade and End Fade parameters, both of which can function as a fade in or fade out. The end fade starts when a note off is received.
When Start Fade is an immediate fade out, then it is ensured that the LFO will start at the defined start phase on note-off. This way you can do a pure note-off LFO.
When in Tempo Sync mode, setting the frequency via a dialog bar now also supports a "Bpc" unit suffix meaning Beats Per Cycle. This way the conversion to "Cpb" (Cycles Per Beat) is done for you.
This improved LFO is also implemented in the MuSynth, MuSampla and MultiSampla devices.
New "Note Dispatcher" module. This module dispatches the incoming notes (events) to one of the outputs depending on the mode:
Random: Whenever a note-on is received, a random output is selected.
Round Robin: Whenever a note-on is received, the next output is selected. And when a note-on with Special Key is received, the output is reset to the first one.
Keyed: Whenever a note-on with Special Key is received, the next output is selected.
Key Range: The note-ons in the key range from Special Key to Special Key + Num Outs define the output.
New MIDI Channel Remapper module to remap the 16 MIDI channels to another channel.
New One Pole Lowpass module.
Renamed the term "Session" to the more familiar term "Project".
New Sinc-16 sample interpolation algorithm. Sinc-16 interpolation sounds much better when transposing samples which contains lots of high frequencies aka trebles.
When working with many tracks and audio parts, scrolling, zooming and editing the composer is (much) faster now.
Number MIDI inputs and outputs has been doubled from 8 to 16, resulting in up to 256 possible output channels.

Improved

Improved control over the sample interpolation mode: Anywhere sample play properties are defined there now is an extra [Options] button. By default all sample players use the global preference so interpolation mode can be easily changed for all sample players (including all multi-sample zones) that use the global preference.
New preference "Auto Loop Recorded Sequences".
New shortcuttable function: "Edit Tempo Changes" now is a shortcuttable context function.
Legato function now works to the next note anyway, independent whether the next note is selected or not.
A rack's own note key names now have priority on the note key names of the first synth in that rack.
Composition: Insert/Delete Time Slice function now also takes the tempo track and markers into account.
Multi-Point Envelope, Note Mapper and WaveShape editors now also have a preset name display and previous/next preset buttons so to easily navigate thru the library presets.
The "Select Previous Preset" and "Select Next Preset" shortcut functions now also work for Multi-Point Envelope, Note Mapper, WaveShape and all other types that use preset files.
Dropping a VST DLL file on the [+] track button now creates a new track for a new rack with that VST plug-in.
The Virtual MIDI Keyboard can now also be set to match a QWERTZ keyboard layout and also a fully user defined key setup is supported now.
New shortcut functions "Rewind One Step" and "Forward One Step".
Finetuned MuSynth UI layout.
Improved time bar and time grid layout for when in real time mode hh:mm:ss.
Parameter editors with only a label (eg in MuSynth) now have a "Edit Value" context menu.
Renamed the "Audio File" object type in RAM to "Audio Stream". This way there is a more clear differentiation between an Audio Stream (=Mu project object) and an Audio File (AIFF or WAVE file on disk). So the question "Delete audio file X?" now is about the file itself, whereas "Delete audio stream X?" is about the streaming object not about the file.
Pure Delay now has a samplerate-independent maximum delay of 2 seconds.
Increased the efficiency of several functions, e.g. when importing large MIDI files or having recorded ten thousands of events.
Also loading projects could be a bit faster.
Zooming in/out in the composer and part editors using a shortcut or the scrollbar buttons now focuses on the play cursor (if it's already visible) instead of the center of the editor.
Improved shortcut system: Less chance that a shortcut is not processed because of a UI focus mismatch.
New shortcut function "Set Play Position At Mouse Cursor".
Automation editor now also supports inputting parameter values in their specific format eg "2450 Hz" for a cutoff parameter automation.
Improved the sample playback engine when in backward or alternate loop mode so no double samples are played at the returning points.
Slightly improved sound quality of some of the Multi-Form Oscillator transforms.
When exporting individual sequences as a MIDI file, now the MIDI file extension always properly is ".mid".
New "Scroll To Play Cursor" shortcut function.
Sequence object display: If no sequence then right-click will also popup the relevant choice list.
Sequence object display: Tooltip only displayed when name is not fully displayed.
Creating the graphic overview data for an audio file is faster.
New preference "Create Audio File Overview Length Threshold" defines when to create a graphic overview .OVW file for an audio file.
Manage Audio/Sample Files: When you move audio files into the project's 'Audio' sub-folder, also the .OVW file is moved too. (if any)
Browser -> Samples: Support for multi-selected drag-drop.
Event Monitor now shows relevant info for MIDI clock events.
New "Update To Modified Audio Files" function which will update the audio file project objects to any changes applied to the source file. This function is only visible if the "Auto Check For Modified Audio Files" preference is off. (see next point)
Added new preference "Auto Check For Modified Audio Files". When switched on, then when an audio file has been edited externally and you switch back to the project window then a question pops up whether to to update to the latest changes. If this preference is switched off, you can still update to the latest changes using the new "Update To Modified Audio Files" function.
When switching a project off, all used audio files are closed, which makes them available for external editing. When a project is switched on again, all used audio files are reopened.

Fixed

Inputting certain parameter values (eg Multi Mode Filter Resonance) was not working correct.
Export Tracks As Audio Files: When multiple main tracks were connected to the same rack/module/plugin, only the last such track was available as an audio file.
Export Tracks As Audio Files: When a main track did not contain parts but its sub-tracks did, the main track was not exported.
When loading a new preset file into the Multi-Point Envelope the editor window title was not updated.
Note Mapper editor: "Input" and "Output" labels were not displayed right.
Fixed an issue when editing numeric pitch-bend values.
Sequence editor: When inserting a note, the property panel shows the data for that note, but when undoing the insert, the property panel was not cleared.
Sequence editor: Changing aftertouch and pitch-bend values via the property panel was not working correct.
Some MuSynth patches could contain a pitch/filter LFO with amplitude at 0%.
MuSynth: Fixed a problem with the polarity of the amplifiers sustain level.
MultiSampla editor: Pitchbend knob had a little vertical offset.
Sequence editor: When changing the editor grid, the event property panel now immediately takes that into account.
In rare specific cases editors could open with an improper size.
Pitch-bend automation editing: Couldn't type in a negative envelope point value eg -50%.
Fixed a sorting issue in the meta-parameter map table.
Fixed a possible memory leak when quitting.
Via right-click audio marker -> Edit it was possible to set the marker beyond the end of the audio.
Some parameter values were not displaying decimals while intended.
When deleting the audio file used by an audio part, the graphic was still shown.
Fixed a possible crash bug when reading MIDI files with long text meta-data.

Improved behavior when loading sessions with registered VST plugins of which the DLL has been moved to another location.
Session browser -> "MIDI Files" and "All Files" now also have relevant options for the Where field.
Optimized speed for certain sequence functions especially noticeable for sequences with thousands or more events.
Improved inputting of parameter values in the event list editor, logical selector, meta-parameter map editor, ...
Sequence Player module now has an On/Off switch.
Modulation Monitor now also includes a text display that displays the modulation value.
Improved the way how the display string and default value is defined for the modular meta-parameters. It's simple now: The defaults are defined by the first parameter mapping for that meta-parameter. To control this, the meta-parameter map editor now supports pushing a mapping to the top.
Top keyboard has scroll left+right buttons.
Clicking the time bar to set a new play position now has instant response.
Mixer strip modulation mode changed to multiplication.

Fixed

Fixed an issue with the tooltips while dragging objects around.

The level meter of a mixer strip (of a rack) now is draggable and represents the mixer strip module.
MultiSampla: Pitch and filter LFO & ENV Amplitude defaults to 100% instead of 0%.
Composer, note editor, multi-sample editor: Shift+click+drag upon a part/note/zone now starts a selection lasso.
Browsers: Clicking an object/file previewed it, but only once if it was not already highlighted. Now each click previews it again.
While moving markers in composer, audio- and sequence-editor, then the current marker position is displayed in the info box.
When saving a preset file using a file name that differs from the object name, the popup question alert now explicitly includes both these different names.
File browsers: More file browsers now memorize their last location.
Improved support for changing the samplerate or blocksize during a session.
MuLab: Finetuned behavior when doing Audio Setup.
Previously the whole session was reloaded, including all plug-ins, which also caused editors to close etc. Now the session stays intact and only when the samplerate has changed or blocksize has increased then all plug-ins are updated.
MUX Modular Plug-In: Demo version now properly fades to soft noise instead of fading to silence (almost silent noise).
MUX Modular Plug-In: Vst wrapper: More tight checks on the info given by the host. (eg avoiding negative tempo values from host)

Fixed
