I've moved towards the MPC, since my Mac Book Pro died (it didn't like coca-cola
). I've got a whole bunch of songs half finished but I'm trying to record, then cut and edit in the DAW, then prepare samples, snippets but also whole loops to feed to my MPC. With two purposes: improve my workflow in the studio and to prepare a live performance parallel to that. There's some non music related work in between but this summer I should make bigger steps.
The MPC has a nice workflow. I try to determine the key (& related pitches) and the tempo before starting the song, or change very early on. My sample library needs organising, and is growing steadily after I neglected it for some time.
I also take my old EMU Command station to jams with friends, it's become a good friend of the MPC, switching, syncing sequences.
IMO a live performance should be continuous and entertaining to avoid it becoming static. Also sounds need to be different, and there should be a progression in the set (to tell a "story").
