I usually use a Vector sequencer with a MIDI TYPE swap cable to get it to talk to the PolyC. I am aware of the Type A and B midi situation and have had this working in the past. I tried to use the PolyC today though and it didn't work via midi. Pressing the trigger button creates a sound, as does the GATE IN jack. MIDI Troubleshooting so far:
I have tried all midi outs on the Vector and they're working as expected.
I have swapped cables to ensure it is not a cable thing.
I have tried multiple type A to B converters
I have connected to my Moog Subs37 as a midi keyboard to send midi to the Poly C with and without a MIDI TYPE converter in place.
I have followed the factory reset instructions in the PolyC manual.
I have reinstalled FW 2.10
I have emailed Knobula but was hoping someone here might have a solution.
This ended up being a USER issue at my end. I am not quite sure WHAT I did wrong but now everything is working great. Thanks also Jason for responding to my case email and being so helpful. You are fantastic.
