Craig,
When I sample guitars and or bass, I sample each string and each fret and then layout each string to its own MIDI channel... then with a guitar MIDI controller, one can play the EB bass just like a guitar...
Sounds better in creating realistic bass tracks (an open A string sounds different than the same note fretted on the E string, etc.).... slides between notes can be somewhat realistic and the player can control the timing of the slides, etc....
Comes out awesome by the way. Just a suggestion. You can create a keyboard layout or what I call a gMIDI layout of the samples in the RAMPLER.
