This article provides a list of pedals compatible with Osmose, describes how to calibrate them, and explains how sustain works with the internal sound engine of Osmose.

pedal compatibility and recommendations

There is no established electrical norm for pedals in the industry, so, unfortunately, there will be several pedals that don't work well with Osmose. Here are the ones that we found to work flawlessly:


Behringer FC600 [RTS assignment]
Clavia Nord Single Sustain

Dunlop Volume X Mini

Korg XVP-10

Lead Foot LFD-2

Moog EP-3 [mode: other, knob at max.]


M-AUDIO EX-P [mode: other, knob set low]
Nektar NX-P Universal Expression Pedal [switch set to "2"]

Roland DP-10 [Switch]

Yamaha FC3A

Yamaha FC4A

Yamaha FC7


Don’t hesitate to share a recommendation with us if you find a pedal that works great but isn’t on the list yet.


⚠️ When playing the Internal Sound Engine, we recommend using expression or half-damper pedals instead of on/off switches with Osmose. This is due to how the sustain works in the EaganMatrix:


In the EaganMatrix, sustain/sostenuto holds the actual pressure of a sound as if you keep your fingers in that position. If a preset is programmed to not only change the intensity of the core sound but also produce an additional sound aspect when the pressure value is changed, e.g. some strings scratching or other mechanical noises, this noisy portion of the sound will be triggered in a possibly unnatural sounding way when using an on/off switch type pedal where values jump between min and max. 

Using an expression or half-damper pedal will avoid glitchy noises and produce smoother results.


the calibration procedure

Turn Value Encoder 1 to select the pedal input your pedal is connected to and then click to start the calibration process.


First, select whether you have connected an on/off switch (pedal sustain) or a continuous or half-damper pedal (pedal expression).


Make sure your pedal is at minimum position (or not pressed for on/off switches), then press ‘next’.


Make sure your pedal is at maximum position (pressed for on/off switches), then press ‘next’.


The last page of the calibration process lets you check whether you are able to go through values from 0 to 127 smoothly. Click on confirm if all is okay.
