life of memory

This is probably a stupid question but can't find any info on it sorry. Please let me know, are the sticks on MPC4000 forever good or fail after a lot of loads and deletes. If the letter, is it better to delete memory prior to powering the unit down or just turn off the MPC without deleting te ram?

No thats not how it works. Theres no need to delete prior to turning it off, and they dont get worn out from loads and deletes. They will function until they fail and that has nothing to do with how you operate your mpc.

in most cases the RAM should last as long or longer that the MPC.

good luck
