Hey! I bought my first MPC2KXL at the week and it have problems.

1, Problem
At sampling, trimming and programming randomly crashes without any reason.

If i press the top line pads (13-16) with too much power then the mpc freezes

Floppy reader is removed, cuz’ it didnt work.
1.14C OS (I’m about to update, but i need to buy a floppy reader)
SMPTE Card Removed
New pad sensors from MPCSTUFF

Any solutions? :worthy:

As a 1st step: remove the memory expansion and check if the XL reacts the same.
If the Simms are located below the pads (I couldn‘t quickly find a view), there‘s some probability they loose contact by bending.

Parts of contacts may have aged
vertical Simm size (there are many variants) might be too high
solder joints of the memory section aged, inspect by a magnifier

Also check Simm contact area for corrosion.
If you find needle-point like traces, it may help to insert the modules in different order.

best of luck
