Term is used in reference to a synthesizer or sampler that uses sample data for the raw building blocks of the sound generation. It is a means to assign each sample to a particular key or range of keys. So a piano keymap would theoretically have each tone from the entire piano keyboard mapped to exactly the same keys on the synthesizer or sampler.

I have an edirol pcrm50 midi keyboard controller. I am trying to keymap samples from the mpc2000xl onto the edirol controller. How do I do this?
thanks..
