Hi I have the 16v One and as of recently I’m having problems with my middle B “hanging” - but only when the key is played at high velocity. MIDI panic works, so it’s not a hardware error I guess? I updated to the latest firmware, but no change. Tried different settings in the midi panel, all pedals etc are plugged out - still the note hangs. Anybody has had the same issue and/or have any ideas for what I might try? The synth is pretty useless right now 😬 Best, Lars ---

Sorry for you! I suppose this to be a key-bed related rather than a firmware issue assuming you are running v1.8.1 (which you stated). Before this update, I clearly would have blamed the firmware, but from what I experienced over the last week -since I did the update and thorough recalibration- for production with heavy sequencing over MIDI as well as for playing live on it, I would say it’s the middle B itself. Did you run the internal tests and calibration routines? I know this is a big pain, but sometimes at least shows what’s going on. For a quick analysis I would record the MIDI output during play, and once it hangs, look at the protocol.
