The first line in the menu will display the control name – e.g. “Drive”. The second line displays the currently assigned MIDI controller. When no control is assigned it will show the Learn option. When Learn is selected, the menu will disappear but the control will wait for the first MIDI event that it detects. Once you change any control in your MIDI controller, this control will be assigned to the corresponding Stomp control.
Once the control is assigned, right clicking on the control will show the linked MIDI control ID below the control name as follows:
Linking Toggle Action controls to Notes works the same way and the assigned MIDI Note ID will show as follows:
The third line displays the Clear option. Selecting Clear will clear any current assignment and the control will be assigned to “None” as its MIDI controller.
