Finally got an Answer to this problem...
This Ish! happens when you have done MAJOR changes to your sequences
and sound envelope's, without saving.
The crashing will appear when you "Stress" your MPC by playing your Song, with allot of Sequences
and samples that you just changed.
I You do not save! The MPC must keep/save them changes in its memory.... And will sometimes crash.
I also think that this problem has something to do with the quality
of the Memory chips, but thats just my opinion.
Its not a bad thing thoo, to save your worx more often
