Unfortunately, I've noticed that some computer programs add their own extentions on to the file name - and this is something that you can't see.
I recently discovered that when I "render" audio files in Ableton Live on my computer(this is their way of saying save to wav.)they will not read in my MPC.
Get this: after that I simply opened the files in Audacity, and resaved them as wav.s - they work in the MPC. This tells me that Ableton must be putting something on the wav. file that the sampler doesn't read.
