I have an MPX16 which I take live. i use it for the keyboard parts of 'in the end' by linkin park, its small and fits on my stand. i also used it at christmas to fill out 'stop the cavalry' and for a few other single shots. i have a single shot on my dwarf as a sound in 'baker street', and I have an organ sound that I play with my 12 step for 'brick in the wall'. The MPX and Dwarf/12 step are not connected.
So I thought it would be nice to get the things together and bought an MPC-One. Loved that, played around with it but thought if I am gigging it was a bit more of a faff, so I upgraded to an MPC Live II, which were luckily cheaper as the Live III was rumoured.
I haven't had a chance to get round to getting together what I want to get, but I do want to be able to trigger sequences, as well as playing the synth stuff through that - first goal is to get 'Power of love' on the footpedals through it, which I can't do on the MPX, as that is a pure sampler, and some of the synth parts on the power of love are the same chords but held longer.
I am aware I could do that with a soundfont on the dwarf, but havent' got that far yet!
