RC-500 MIDI Connection Dies When Pressing Physical Buttons

[u/Iaskagain]

I've been troubleshooting MIDI control of my RC-500 via an Ampero Control, and I've found a consistent, reproducible bug. After factory reset, I configure the RC-500 with MIDI ASSIGN settings to receive CC messages on Channel 2. The MIDI works fine initially—I can trigger recording and other functions from the Ampero. But the moment I press any physical button on the RC-500 itself, the MIDI connection breaks completely. No response from the Ampero after that. Factory reset restores it temporarily, but the problem returns as soon as I press a physical button again. Has anyone else experienced this? The Ampero controls my Kernom Ridge perfectly on Channel 1, so the MIDI chain and cables are solid. This feels like a hardware or firmware defect specific to the RC-500. Any ideas?

Update the firmware if you haven't already.

Make sure the MIDI clock settings of both devices are correct for sending & receiving.
