Thanks a lot for testing that @monospace0 🙏 That really helps narrow it down.
It looks like devices that require MIDI power on boot can sometimes trigger Reliq’s DFU mode when connected to MIDI OUT 1 before startup. Unfortunately, we don’t have an immediate fix for this right now, but as you mentioned, using MIDI OUT 2 or 3 is a good workaround.
We’ll also make sure to add a clarification about this in the next manual revision. Thanks again for helping track this down!
