Track(s) muted while playing pads intensive

Dealing with a problem right now. Got the free JJ OS on em.

I got a sequence running with multiple tracks. Got a small loop in one program and several drumsounds in an another program. Im running the small loop throughout continuously. Got like 5 tracks running with the drumsounds program, each playing an another sound. Now I'm trying to add some uptempo hihats from the drumsounds program. But everytime i try to add those hihats other tracks seem to automatically mute while playing. Ive Tried doing the same with other pads and they also seem to automatically mute other tracks while quickly hittin the pads. Even the loopsample in an another program mutes once in a while.

Seems like the MPC is reacting on hitting pads fast. What could be the problem?
All my programs are on poly, no voice overlaps etc..

Its regarding the 2500 btw

here, read this thread:

thanks, ive read the whole 32 voices question but that is not relevant for me. I use one loop from program1 and 5 drumsounds from program2. Even if only play the loop and 2 drumsounds and then rapidly hit another pad of program2 with the drumsounds, the problem occurs. Never had this problem with the mpc1000.

I definitely not using 32 voices.

have you looked at your polyphony meter? you'd be surprised.
