Every once in a while, once per session or so, my Ambika voices go silent. The LEDs still flash indicating notes are being received and played, but not sound.
If I go to the screen where you assign voicecards to Parts (where you see [1] [2] [3] etc) and “unclick” a voice and the “click” it again they come back on.
It doesn’t seem to ever happen within the first 30 minutes, but nothing feels warm enough to be a concern. And hours may go by before it happens again.
Not a good thing during a performance 
Any ideas?
thanks, Drew
