I don’t know why, but the ZAQuencer can’t seem to send expected MIDI to my Pittsburgh Modular MIDI module (old version). I have checked that it sends fine and correct to MIDI in on my computer, and I have checked that I can send a MIDI sequence from the computer to the Pittsburgh module correctly (via Nodal; this works just fine), but when I send a note-pitch-randomized 32-step sequence from the ZAQuencer to the Pittsburgh, I generally get just a drone of a single note that may change occasionally. On the software end, MIDI Monitor shows that the ZAQuencer is sending note on at 127 velocity followed by note off at 0 on channel 1, which looks right to me.

I’ve tried setting the ZAQuencer to all of 16 MIDI channels, both the A and B physical outs (with A, B, and AB out settings for the sequence). I’ve tried recording a MIDI sequence in Logic and replaying it to the Pittsburgh — this has exactly the same effect as sending directly, so I don’t think it’s a purely electrical issue, but instead, a disagreement about the MIDI data.

Do you have any idea what might be going on here?
