Here’s what’s new in MuLab 6:


  • Docked part editors that auto-follow the focused track.
  • Direct buttons for showing/hiding the browser, mixing desk and session modular area.
  • New “Export Consolidated Session” function for making a complete session folder for export to another system.
  • New “Export Tracks As Audio Files” function which exports each main track as a separate audio file.
  • All rendering-to-audio functions can now be interrupted by pressing ESC.


  • Audio parts now give you full control over the fade-in and fade-out curves and show these curves on the audio data.
  • Audio parts: When changing the gain or stereo pan in the part property panel, this is applied to all selected audio parts.
  • Sequence parts: When changing the transpose or velocity in the part property panel, this is applied to all selected sequence parts.
  • New “Add New MuSampla Track” function.
  • New “Insert Time Slice” and “Delete Time Slice” functions.
  • New “Select Similar Sequence Parts” function.
  • New “Increase Tempo”, “Decrease Tempo”, “Half Tempo” and “Double Tempo” shortcut functions.

Part Editors

  • Sequence editor now has two tools: The standard arrow tool (cfr M5) and the pencil tool which makes it easier to quickly insert and delete notes with a single click.
  • Sequence editor now has an event property panel for quickly changing the (selected) event values in an alternative way. With optimized undo/redo support so to avoid redundant undo/redo steps!
  • New “Transpose -1”, “Transpose +1”, “Transpose -12”, “Transpose +12” sequence shortcut functions.
  • Envelope editor now has an envelope point property panel, similar to the event property panel in the sequence editor.
  • Audio-, sequence- and automation editors now much more clearly indicate the active/inactive region.
  • Improved Event List Editor: Better layout + events that are outside the actual play region are grayed
  • Event Graph Editor: Support for individual note keys, which is handy to select the velocities of a certain key.

MUX Modular

  • New MuSampla version 2.
  • Improved MuDrum:
  • Improved mix-racks.
    • MuDrum sampler plug-in slots now also have an explicit On/Off button.
    • MuDrum: Pad editor is switched also when playing the pads.
  • MultiSampla now has 4 stereo outputs so you can route specific zones to a separate output
  • Modular Feedback Delay now has a “Invert Feedback” switch.
  • Rack slots and module buttons now include a process on/off switch.
  • Multi-sample editor: Zone editor now integrated as a docked sub-editor.
  • Added support for note key names e.g. for when a target module defines C3 as “Kick”, D3 as “Snare” etc
  • All embedded sample displays (e.g. in MuSampla and in the multi-sample zones) are fully functional now.
  • New “Focus Previous Rack” and “Focus Next Rack” shortcut functions.
  • These functions make it possible to also use MuLab as a stage rack with a bunch of preset racks that can be selected via MIDI.


  • Improved curve editing: Curve edit fields (e.g. in the Audio Balancers) now support direct editing i.e. (alt+) drag up/down to change the curve without having to open the curve editor. Opening the curve editor is done via double-click. Plus other detailed improvements wrt curve editing.
  • Improved and extended browser functionality.
  • Added support for saving/reloading the sample markers near the source sample file.
  • Optimized audio engine which should result in less drop-outs when high CPU load on certain systems.
  • Many more preferences so to tune MuLab to your flavor.
  • Improved look and feel.
  • Improved factory library.
  • Many more improvements which all together make a big difference. See below.


  • Added support for a factory Start.MuSession which is opened and auto played on initial startup.
  • Support for a ‘Focused Track’.
  • “Add Automation Sub-Track” now also includes Controllers, Pitchbend and Aftertouch.
  • MultiSampla now also has a Pitch Bend Range control.

  • Fixed a problem when dropping a MuClip on the sequence editor.
  • When adding racks while the music is playing could result in hanging notes. Fixed.
  • Event Graph Editor: When drawing a line to draw/edit a curve, the line color was always black even on dark backgrounds. Tuned.
  • Event graph editor: Fixed a problem with selecting velocity beams in certain specific cases.
  • When double-clicking envelope points, the popup editor didn’t take the part start time into account. Fixed.
  • A single click on an envelope point does not create an undo step anymore, as that was a redundant undo step.
  • Sequence editor takes some extra space at the right into account so to easily manage any markers (e.g. loop-end) at the end of the sequence.
  • “Auto Collapse/Expand Racks” now is a standard context function and not only accessible via shortcut and right-click on the collapse/expand rack button, but also via right-click on mixing desk background.
  • When focusing modules (e.g. racks), also the modular area reflects that by solo-selecting the focused module.
  • When switching presets for rack slot modules, in certain situations the rack was not properly updated. Fixed.
  • Fixed a problem with the User/Settings sub-folder after having manually deleted the User folder as a kind of setup reset.

  • When splitting a unique sequence part and the “Standard Copy Part Is Shared Copy” preference is 1 (= yes = true) then the split will use shared sequences.
  • Ensured that the preferences window never needs horizontal scrolling to read the description.
  • The “External Audio Editor” setting has been moved to the Preferences.
  • Optimized composer part management.
  • Importing MP3 audio files now is interruptible by pressing ESC.
  • Fixed a nasty crash bug when copy-pasting a MUX device (e.g. MuSynth) inter-session when such MUX device was using samples as well as using effects in the device FX slots.
  • When using “Save Preset”, “Save Preset As” and “Delete Preset”, the browser now is automatically refreshed.
  • When recording parts and the part is put on a collapsed track then that track is automatically made visible.

  • Changing the pre/post switch could result in a lot of audio clicks while dragging the pre/post indicator. Tuned.
  • More visible log details when scanning VST plug-ins.
  • When the user settings can’t be saved, an alert box is shown which optionally also opens the relevant doc file.
  • Saving color presets now uses a more simple name dialog instead of a full featured file browser. This avoids that color preset files are saved on a irrelevant place.
  • “Main Editor Grid Contrast” and “Piano Key Lanes Contrast” preferences moved from Edit Looks to Edit Preferences.
  • Browser: “Where” field now shows a tool tip when the text is not fully visible.
  • Clicking the timebar in the automation envelope editor now snaps the new play position to the selected grid.
  • When there are tracks with no target module, then moving the play position could result in unexpected controller/parameter changes. Fixed.
  • Floating windows bar now always shows the option button so that you can close the bar if it’s not needed anymore.
  • Inserting/removing a modular input/output did not redraw the parent MUX modular area. Fixed.
  • You can now also drag-drop audio files on the [+] track button which will add new audio/sample tracks.

  1. I have used a lot of DAWs and always end up back with MU-lab. The modular environment for designing sounds and creating complete tracks is simply brilliant. It enables a creative flow that I have never experienced in the other DAWs and it is so open ended you end up taking tracks in directions you could not have imagined.
    It has a very straight forward GUI that makes for good work flow and the new additions make this even more CPU efficient, easier to navigate and even more of a creative/ sound design tool.
    I advise anyone to at least try the free version. Give it a few hours (especially the modular environment) and you will experience a DAW like no other.

  2. Amazing how little known Mulab is!
    It’s the only DAW with which I actually finish ANYTHING..
    So simple, so cheap, and there’s so much to do in Mulab free anyway.
    Go on, give it a try! This little company truly deserves more recognition.
