I want to drag a small-ish keyboard on stage with me to play some stuff while my lead guitarist is soloing. the main problem is finding some good sounds to go along with our "classic rock/prog" sound. cheap toy keyboards dont really do the job, at least not the ones we have come across. my question is this: is there a keyboard out there that I can import my own sound samples into? if there is, how cheap can I get something like that? I really don't want to drag my laptop with me to gigs.
