I have noticed that the touch panel has locked up on me a couple times now when adjusting the grain attack and delay in the live granular engine. Everything worked OK for a few minutes then touch became less responsive and then stop responding at all to any touch control, needing the whole unit to be switched on and off to get it working again.
The rest of the synth worked OK but the panel itself stopped responding to any type of touch. It happened twice now in quick succession but only when adjusting Live grain attack and delay, I tried to get it to do the same with other controls in different engines but I couldn't replicate it.
It occurred after the 1.3.0 update and panel update to the 0.3 panel firmware.
