Thanks @whofferbert,
I think I get it now. I just got my FCB1010 hooked up and yup, I tried to midi learn a sooper looper toggle control and it would only trigger it on, not off, so I get what you are saying now. I just ordered the Eureka EEPROM and am really looking forward to finally getting to play with a looper!
Once I get it installed and tinkered with I’ll probably ask you a follow up question here.
Thanks
