Midi CC 50 Solo Ableton and OT MKII

Hey Elektronauts,

I’m working on an Octatrack MKII, and I’ve been following this tutorial: It's Not Overbridge for the Octatrack, but It's Close Enough | Emil Smith - Creative Tech Lead

I’m having an issue with the Solo function using MIDI CC 50. When I trigger it with a low value of 2 and a high value of 127, it plays the selected track just fine. However, after one play, I can’t mute that track. Even if I mute it directly on the Octatrack, it keeps playing.

As a test, I tried using MIDI CC 49, and it works well for muting each track when I select the corresponding channel in the “MIDI To” section in Ableton.

I’m using a Roland Um-One MIDI interface to send and receive MIDI. Has anyone else encountered this issue, or does anyone have any suggestions on how to resolve it?

Thanks in advance for any help or advice!

Does the low value need to be 0 so it’s off?
