I've been a Roland R-8 drum machine user for some time (about 13 or 14 years). I recently purchased an MPC4000 and found it to be loaded w/ about 2 or 3 gigs of sounds. I was wondering, has anybody used this device ? If so, are there any tricks or pointers that would be helpful? It seems nobodys' into the midi stuff. Any logical reply would be appreciated.
