USBMIDI from computer not playing notes on device

Using the most recent firmware, I’ve been sending notes to minichord over USBMIDI from a couple different devices and I don’t get any notes playing?

Tried both ports (which show up properly) from my M1 mac. Also no luck from norns or a DIY host device.

minicontrol works as expected from my computer. Notes show being sent in midi monitor.

Am I just missing some setting somewhere?

Is it a new issue for you? When did you update the firmware? The last modification to the MIDI code was a delay to help out with some specific devices (see Compatibility with USB host mode compliant devices · Issue #72 · BenjaminPoilve/minichord · GitHub). Maybe it had unexpected consequences..

More and more USB midi proves to be a major headache, TRS will be so welcome!

I did a fresh download of the firmware hex from github. Not sure what build that is.

I didn’t have a chance to really debug yet, but I’ll dig into the code later today and build it myself from source.

EDIT - looking at the source now and USBMIDI into minichord isn’t handled at all. I mustve forgotten this from hacking earlier.

So - to clarify - I am attempting to use minichord as a sound module, controlling it from another device.

I could add this capability but I’m unsure which functions would handle note-on/note-off

Oh indeed that is not something that was implemented! It is not impossible to do so, I just did not see that use case initially.

can you give me an idea of which functions I should be looking at for note-on/note-off?
