Hey all.
Current firmware is v2.15.1
The issue is demonstrated in this video:
https://drive.google.com/file/d/1AmVza7 ... sp=sharing

My MPC One has been freezing up if I play a part too fast. it seems like a sort of buffering issue.
It locks up for about 10 sec, during which time pads register when hit but no sound comes out.
After 10 sec. the note continues where it left off and freezes again. The only way I've found to fix it is to reload the project, which is, of course, not possible in the middle of a track during a set.

I have had this problem for more than a year and across several firmware upgrades.
Almost all of my projects consist of drum programs, loaded up with various custom samples.
In the video, it's a lead guitar program.
The Program settings have the pads all set to Note On and Poly. I tried Mono, 2, 3, etc. with no change.
CPU is at 86% in the example in the video.

Any advice is greatly appreciated. Thanks for your time.

If your kits have fx chains per-pad you can "flatten to pad". It will auto-resample all the layers assigned to a pad and sum them into a single sample using the selected fx chain applied to the pad. once it is done flattening, it will clear the fx chain and reassign the single summed sample to the pad you "flattened". I am hazarding to guess maybe you've over loaded your kits a bit?

Thanks, Lampdog and Ultros. I fixed it. I had been applying effects extremely inefficiently on a per pad level. Changed that to Send/Return and solved the freezing issue completely.
