Thanks for this suggestion and your help here. Yes the pedal is looking for a specifc CTRL assignment - No. 20. I think that it will ignore any MIDI signal other than this. I'll try this and your suggestion from the other thread. Sorry to have two threads on this - I started with the one that mentions the Replica - but I figured that people who actually do know how to do this may be put off by the mention of the equipment in the title. So I started another question. Apologies for any confusion.
