no stuck notes but stuck everything. the whole sd1 kept playing the last pattern. I was still able to play chords and solos but there was no response from any of the buttons and I think even the volume slider didn't effect the output (I'm not sure about that). I had these mixed displays one on top of the other, but everything is OK since I cleaned and bent the connectors.
I only have one problem with my instrument. some patterns have "hickups" and fall off the rhythm. it only happens in single (disk) styles , not in custom styles. anybody had this problem?
