I could use some advice for this setup.

I have a S900 sampler and the disk drive doesn't work. If I can replace it this is what I want to do:

I was thinking about buying a mpd16, numark pt01, and somesort of 12-track digital muli-track recorder.

How does that sound?

sounds like you would still need a sequencer...

sell the s 900 to me for real cheap and use the dough to cop a software sequencer...

Good try! I just gotta find an old teac floppy drive with some jumpers and i'm set.

Do any multi-track recorders have sequencers in them?

cubase, nuendo, pro tools, ableton live, tracktion, logic......

I replaced mine with one off of Ebay, "instrumentechs" was the seller.
I think he is on these Forums alot, it worked perfectly.
Don't know if he has anymore, just hit him up.

You can sequence using the s900 and an old atari computer with a certain version of cubase.
