Modular has MIDI integration built in. Modular receives MIDI information and can be controlled by external or virtual MIDI devices.
Setting up MIDI is simple.
In the settings menu, select the MIDI channel that you wish to control modular. Then, tap the MIDI Learn button. You will be returned to the workspace and you will notice that every knob can be mapped to a MIDI control change message.
There are two ways to map a MIDI control change message to a knob.
The first is to tap the up or down arrows to the desired MIDI CC number.
The second is to tap the highlighted knob area an then send the MIDI CC value to the app, which will automatically map the control.
Note: You can map multiple knobs to the same MIDI CC number which allows you to turn all of the mapped knobs with a single control.
