I am running the latest Norns update and I seem to be encountering some issues with dropped, delayed, weirdly advancing notes. I am using a Korg SQ-1 sequencer > DIN MIDI out > Roland UM-ONE MK II MIDI USB interface DIN MIDI Out > Roland UM-ONE MK II MIDI USB connector > Norns USB.
If I disconnect the MIDI USB interface from the Norns and from the SQ-1 and plug it back in to any of the USB inputs on the Norns the dropped, delayed, weirdly advancing notes occur as the sequence continues to advance. Also returning from sleep, if USB MIDI interface is fully plugged in, this issue occurs.
It seems like the only way I can resolve it is to restart Norns without the MIDI USB interface connected on either end, load e.g. Molly the Poly, plug in the MIDI interfaceand the issue goes away. But when I try this procedure to “fix” it it doesn’t seem to always resolve the issue (but it could just be me trying too many things…).
Is this Norns? Something specific to the MIDI USB interface? Or how the SQ-1 sends out MIDI?
Any advice on how to resolve or address is greatly appreciated
