Sample Player ? Sequence Player ?

Hi,

I'm using Cubase (Studio 4) to program drums in Midi. The Cubase Midi tracks trigger drum samples on my hard drive. I would like to take these midi tracks and samples on stage but do not want to have a PC or laptop on stage. So I'm looking for a hardware sampler, sequencer, ... ? Let's call it "The Box".
The Box should enable me to do some very straightforward operations in my home studio: move the Cubase Midi tracks and drum samples from my PC to The Box. The Midi tracks would be split into sequences (intro, verse 1, verse 2, chorus, bridge, outro, etc). When the sequences are in The Box, I'd like to build the song in The Box (but using either Cubase or a dedicated software editor to do so).
On stage, The Box should just enable me to do the following operations:
- Start/stop the song;
- Hold a sequence in the middle of the song (for instance when a musician is soloing for an unknown number of bars);
- Jump to the next or previous (or any) sequence (for instance at the end of the solo).
I won't do any sampling with The Box, don't need any FX or sample manipulation toolds, etc. It should be just a basic sample and sequence player !
I did some extensive research and just couldn't find The Box that would fit the bill. I bought an MPC1000 but although it does a lot of the above, it has some serious limitations: it is a pain to program, there is no software editor, in song mode I can only jump to the next sequence, ...
Can someone help me identifying The Box that would fit my needs ?
Many thanks.

Guy

Thanks Lampdog.
Is your assumption is that I will make all seqeunce changes in real time? That will prove difficult. My main instrument is the keyboard and I just can't use my hands (or feet) to change each and every sequence. I just want the flexibility of changing sequences as need be (and hopefully that won't be too often). Hence, the Song Mode ...
