well, I guess there could be too many reasons behind “voices don’t work in a specific kit” for people to chime in
synth voices? sample voices? any trig mutes you didn’t consider? track volume all the way up? any scenes active that could mute the sound? Which OS (there were some issues regarding dead voices in 1.45A if I remember correctly)? … You get the idea, right?
There isn’t any hardware - related error going on, considering that the pads do respond when you load a new kit, I guess
So, I guess you could copy the sound of the corrupted kit into a new, working kit to check out if it is sound related, maybe? Definitely do the upgrade to the latest OS if you haven’t done so by now.
Well, if we two would be havin’ a beer and discussing this specific issue, I would just say that if the corrupted kit isn’t the only one that matters on the whole machine and all others are working perfectly fine as they should, then I would forget about it
But that’s just my 2 cents and I hope the “but it is a very expensive machine and everything should be working perfectly” - party won’t be all over me for this, but I tend to see things pragmatically as long as my purchases deliver overall satisfying results.
cheers and sorry for not being able to help you out, I hope the rytm is giving you some nice beats nonetheless
