M8 Docs   MuDrum

The MuDrum is a super-flexible drum module capable of creating almost any drum sound, both sample-based or virtual analog or any hybrid combination of that.

The left side of the MuDrum shows the 12 drum pads each of which can generate a drum sound. These 12 pads are triggered by the 12 notes in the octave, independent from which octave you play in. So e.g. each E note will play the 5th pad.

Below the 12 pads there are 4 racks. Each of the 12 pads can be routed into 1 of these 4 racks. These racks work very similar as standard racks, see the rack doc page.

The right side is the editor for the focused drum pad.


  • Click a pad to play it. The more you play on the center, the louder the pad will sound.
  • Clicking a pad will also select that pad and the relevant pad editor will appear at the right side.
  • Double-click the pad name to rename a pad.
  • Below each pad there are [M] and [S] buttons for muting/soloing that pad.
  • At the bottom of each pad there is a jack. Click-drag this jack to connect the pad to one of the 4 racks:

  • Drag-dropping a sample onto a pad will set sampler element 1 (see below) for that pad to the dropped sample.



  • These MuDrum racks work similar as other racks. For detailed info see the Rack doc page.
  • The MuDrum has 4 stereo outs. When the MuDrum is plugged into a rack, only output 1 is used. Outputs 2-4 are only usable when MuDrum is plugged in in another MUX, where you can see and connect the different outputs in that MUX' modular area.

Focused Pad Editor

Each pad consists of 3 elements: 2 sample players and an extra MUX Modular layer in which you can create your own drum sound and use VST plug-ins.

The sample players work like this:

  • To load a sample, click on the sample display.
  • You can also drag-drop a sample file onto that sample name display or on the audio display.
  • Once you've loaded a sample, you can use the previous/next sample buttons to step thru the samples on your system.
  • You can choose a start, loop and end marker and a loop mode. Note that by default a drum pad is set to infinite release so that samples are played to full length. But if you combine that with a loop the sample keeps playing forever. In such case lower the release or set it to no loop.
  • Managing these markers is done via the audio editor's time bar, see the audio lab doc page for more details.
  • Note that you can also use markers that are in reversed order for reversed playback!
  • Semi: Changes the pitch of the sample in semitones.
  • Cent: Finetuning of the sample from -50 to +50 cents.
  • Gain: Volume of the sample.
  • Pan: Panning of the sample.
  • VS: Velocity Sensitivity of the sample from -100% to +100%. If you set sample 1 to +100% and sample 2 to -100% you get a velocity crossfade.
  • Att: Attack time of the volume envelope.
  • Dcy: Decay time of the volume envelope.
  • Rls: Release time of the volume envelope.
  • D.Tm: Delay time. Will delay the sound by up to 300 ticks.
  • D.Rnd: Delay random. This will randomize the delay, for making more natural sounding flams.
  • The first of the 3 plug-in slots also receives the incoming events so you can use these events in a MUX that you plug-in there!

The "MUX Layer" is a different beast though. You can insert any MUX preset here, and edit it as you want with all MUX modular power like synthesis modules, LFOs, envelopes, ... (multi)samplers, VST/i's, ... almost endless modular possibilities! For detailed info on the MUX, click here.

The audio from both samplers and the MUX layer flows thru the 3 effect slots at the bottom in which you can put insert effects like EQ, compressors, etc. The first of the 3 plug-in slots also receives the incoming events so you can use these events in a MUX there! You can also set volume and pan for the whole drum pad as well.

Each of the 3 MuDrum elements has it's own process On/Off LED and options button. This also means that you can save each element to itīs own preset for later reuse!

Each drum pad, i.e. the combi of all 3 elements together with their common effects can be copied/pasted and loaded/saved separately, so you can exchange MuPad patches between different MuDrum sets, even inter-project.

And of course the whole MuDrum set can also be loaded/saved as a preset. This can be done via the control bar at the top-left of the MuDrum.
