Using a MPC as a sound module?

I want to trigger about a dozen or so select sounds from a sound source. I know most of you will say get a sound synth/module such as a Motil, Fantom, ect. But I don't need that many patches, and I would like to get very specific with the sounds that I choose from various software libraries. Could I use a MPC to store these select sounds in the memory bank to then trigger them live with the pads and with an external midi keyboard controller?

I want to use this setup for a heavy touring group that focuses on live playing with a lot of acoustic instruments. If we get into sequencing in the future it would be minimal. Most importantly, I just need to be able to have some customized pristine drum, percussion, bass and keyboard sounds ready to be triggered.

If this could work with an MPC, which model should I consider first? The smaller and more roadworthy is a priority.

Or, am I looking at the wrong machine for what I want to do?

I do not have a mpc yet. I'm trying to figure out which one would do me right.

Would the MPC-500 work well enough? How many sounds could it hold? Polyphony?

Download the 1k & 500 free manual and read through them.
Also look into any addendums, OS changes and so forth cause everything single capability may not be in the manuals.

1k is small and powerful..

I am using the MPC1000 in much the same capacity. Most people seem to use it in their home studio for sequencing, but it works fine for live settings as well.

A friend of mine recently asked me to help him do live versions of his solo project, which was mainly created using VST instruments in Cubase; with the MPC we can import any of the MIDI sequences and sounds and pretty much recreate each track in a live capacity, allowing ourselves some room to perform piano solos or whatever...

In my primary band, I use the MPC as a loop based instrument, building up the rythm section live. I have two synths hooked up to it, usually one I'll use to build a bass loop, recording into the MPC and just play the other one live. Sometimes I'll sequence both and pick up my guitar....

For both projects I'm also planning to add a track of MIDI data which will trigger video samples, sometimes as a sequence, sometimes as a live performance.....

You could also use a laptop and software to achieve this sort of setup, but the MPC just feels a lot more hands on to me....
