Finally took the plunge and got my OP-1 & PO-20 yesterday - having so much fun!
I put together a chord guide for the PO-20 - makes it easier to jam if you’re not a theory-head
Thanks for sharing, really useful and clean.
Typo error : the first is named “10” instead of “1”.
Long since sold my PO20, but this is still really useful! Thanks!
