hey guys. ill sample some sounds onto it and they will play back fine for a while but after several days some of the samples will playback with a funny distorted bug out noise at the end or they will barely even play back. i've noticed it doesnt do this in the internal banks. is this a card issue?

sounds like.
try a format.

yo sometimes restarting the 303 will fix this. mine does this too when too many samples playing at once.
