I was spamming the A4 with sysex which was targeted to it⌠so what happened here was not a bug, but an accidental triggering of a certain debugging commandâŚ
I did see some odd behaviour with the machine though when sending waaaaay too much CC messages at once to itâŚ
lagging UI / weird blinking lights⌠so yeah imo what can happen is some sort of race-condition / overflow when too much/too fast MIDI is sent, which may make the OS barf, and in your case it somehow messed with the voice calibrationâŚ
conclusion:
- do not send waaaaay too much CC messages to the A4 at once.
- do not send sysex commands to the A4 unless you know what youâre doing.
that said, the A4 MIDI is usually rock solid.
