I recently bought a used Motif XS8. It is now giving me strange sounds once turned on - scratching, hissing, occasional screeching. If I play “through” this, or wait 10 minutes or so, all the strangeness disappears. Help? Any ideas?
Additional Info - if it has been “on” for 1/2 hour or so, and I turn it off, and back on, I do NOT have the strange sounds.
