hi,i just purchased this beautiful synth and im having some
issues.when i first got it i use the headphone output and now the
sound comes and goes.The poly output works fine,and you can hear the
synth section in the background,but its a constant drone.Sometimes i
will flip the on off switch a few times then press the keys and the
sound comes back,then slowly fades.After awaile the sound stays.does
anyone know the cause of this? thanks
