Inconsistent channel value on midi note-on

Hi all. I’ve encounter a piece of gear the my MnM can’t seem to talk to (a Bastl MicroGranny)

I hooked the MnM to my PC so I could monitor the midi messages it sends and I’m seen most of my note messages are being sent to channel 1 instead of my selected channel.

On the MG this results in lots of stuck notes and notes not playing. Weirdly , this same midi data has been fine in every other synth I’ve hooked to the MnM.

Is there something about midi channel and note on messages that I (and maybe the bastl folks) don’t know?

Thanks.

Did you ever get these issues ironed out?

How have you liked the MG lately as I’m thinking about buying one soon?
