Hi Rik,

You can only have one MIDI controller at a time unless you get a MIDI merge device.

If you want ModFactor to change NovaDrive presets, keep the setup as-is.

If you want your MIDI pedal board to change NovaDrive presets then set ModFactor's MIDI Transmit/Thru Select to THRU. (ModFactor will no longer change presets on NovaDrive but MIDI pedal board will.)
