MuTools updates MuLab and MUX Modular to v6.4


MuTools has updated MuLab and MUX Modular to version 6.4.


  • 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 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 e.g. "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.


  • 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.
