I think an S950 and an MPC 1000 would be a killer combo. I've been looking to buy an S950 for a while, but decided an Mpc 1000 would be the first to get (sequencer, etc.) I used to have an Sp1200, and wanted to sequnce with that and an S950. I have to say, though, that the Bit Grunger Effect on the MPC 1000 was NOT what I expected. If I'm using this feature correctly, it sounds as if distortion is added to the sample. I was hoping to get that Sp-1200-ish or S950-ish sound using that effect, but now I know that nothing can really emulate the sound of the 12-bit samplers.
Anyways, back on topic, the MPC 1000 could hook up with MIDI to the S950. Then, using the S950 as the sampler, record your sounds and then before or after (whatever you choose) making your beat, I would re-sample the sounds into the MPC1000. That way, you don't have to go out and buy a bunch of floppy disks to save your sounds. To be safe, only keep a few on hand to save samples as you go along, in case of the unit's malfunction. Just save the sequence, the sounds, and everything else into your MPC1000's CF-card, and then ultimately back it up into your computer using USB. I love the flexibility of this. Get the warm, 12-bit sound and the flexibility and ease of use that the MPC1000 offers.
Hope that answered your question. peace.
