Hi Peter/Ryan,
I was just thinking. If you want to connect UNO drum midi out to UNO synth midi in (for the midi clock), is it possible to use a (modified) cable to directly connect the 2.5 mm midi out jack from the drum to the 2.5 mm midi in jack of the synth just to avoid all the cable clutter with real midi cables and the two midi dongles?
If there is some opto coupler needed, maybe it is an idea for IK Multimedia to sell the cable, or publish the schematics and wiring?
Just a wild thought really.
Regards,
Albert
