OP-1 Midid with Keith MacMillen midi expander

HI, does anyone have an experience with connecting the OP-1 to a Keith McMillen midi expander? I’m trying to connect it with other devices but i can’t make it send midi signal. THe midi expander works tho - if i connect a QuNeo controller I can successfully send midi signal to the midi expander. Wonder if there’s something i need to do to set up the op-1. tnx!

From what a understand the midi-expander only works with other keith mcmillen products, if you want to use anything else you’d need something like a iconnectmidi

Oh I see, thanks for the reply.
