Only the K2500 can do resampling, without leaving the machine. The only way that you could do that with a K2000 is to record something outside of the machine and then sample it back into the K2000.(posted 9344 days ago)There is a little trick though that could work for you: Build up your super big layered program. Go to the sample page. Play the keyboard, then hit the record button. You'll actually be able to record "some" of that sound. It may be just enough.
Have fun and thanks for using this users forum,
