dog whistle styled mpc

hello. im having a **** up problem whit my mpc 1000. when ive sampled something and playing it back it ads a high pitched noise in the background, its almost out of my hearing range, like a dog whistle.
its torture garanted!

im sure its not the turntable, mixer or any other equipment but the mpc, 100%
in record mode its all fine, but when i go to trim or program or whatever the sound is there

anyone had this or know what it is? cus this shit sucks!

is your MPC brand new?
does it occur with other sources?

if it's new, I would take it back, but try finding out what is causing it... Is it only occurring on the wave form?

i moved my all my gear some days ago and hooked it up in a potheaded behavior, it was just acoustic feedback sorry

ahhh... ok...

glad to hear you are back on track...
