Output Problem?

I just had this thing working fine from the day I bought it to about 4 days ago, now only my kicks are outputting sound and I have to put the main volume way up. Anything else plays extremely low in volume, almost inaudible, even when I pump the MPC and the mixer up.

Only thing I've done recently is attempted to record a synth, but I was only getting input from the left side.

Any idea what the problem could be?

If it matters to anyone, my MPC is blue. Seriously worked fine just a few days ago, so this is pretty random. Any help is greatly appreciated, this has me kind of bummed out, I really need to work on some stuff this weekend.

EDIT: Now if the main volume slider is at around 80% I can hear snares/claves/hihats/etc. but they're clipping extremely hard. So I'm either in the red or completely inaudible.

None of this is unusual, and you gave to little info to tell anything. Maybe make sure you ain't got any copressor set as an effect. What's your master output level on mpc? are you using your own programs? what OS you got?

No effects, master output is at 0db, it's a mix of my own and stuff I've found. All have the same issue, anything bass-y plays somewhat normal, everything else is either clipping or inaudible. OS is 4.99

I don't know dude, is it from all outs? maybe route pads to 1/2 or 3/4 mix out,
also check it with onboard 16 MB RAM only.
