Hey, thanks for the reply. Yes, I am just using the Analog Keys and nothing else connected. I will try to be a bit more precise here: the sounds stop reacting to velocity from the internal keyboard, not from the velocity assigned to note trigs of the sequencer. This can happen in a completely new project when doing various stuff such as just playing the keys and switching to a different track, rehearsing sounds from the +drive or changing patterns. Using the internal keyboard or an external MIDI controller does not make any difference. The internal keyboard also spits out velocity information normally.
So, to address your reply, the issue sort of requires me to “intervene”, namely just play the AK as a live instrument. Hence also why it is so hard for me to figure out what could cause it.
BTW: I’ve found out that, when, let’s say the sound of Track 1 on Pattern A01 stops responding to velocity, then switching to Step Record mode and creating a note trig by using the keyboard suddenly causes the sound to react to velocity again, at least for a while. It does seem like some weird firmware bug to me, but since I am apparently one of the only ones with this issue I think my unit might actually be defective.
