I have an MPC 1000 with a 32MB ext. Memory card and 128MB int. Memory. I bought a sample back from Primeloops in the form of wav. files and all the samples play on my computer, but once I have transferred them onto the MPC they do not play when i press F5 (on the load screen) and when i press F6 (do it) it says "Wrong File!". Could anybody help because this is getting really annoying.
