used a iConnectivity Mio, which failed every time until i remember i had previously read some models had the ‘midi in/midi out’ labels swapped on the inputs. i swapped the in/out and it worked first try, so just an FYI for any with a Mio; if it doesnt work, swpa the in/out!
HOSA USB to MIDI did not work. MOTU MIDI Express XT did through MAC. Thank you, going to try sequencing the Emu SP1200 like a TR 909. I will report back. – MH
