choices choices

okay heres the thing im choosing btn the 4000 and the 1000 the 2kxl seems not to be factor since the 1000 seems to be th 2kxl killer if your buying them new. seems to make the 2kxl a match you have to spend almost 2 g's when you get the 1000 the only thing missing from being the 2kxl is the 4 outs compared against the 8 outs of the 2kxl which cost you more so 4 for free seems ok. also chromatic assign(i think thats the right term) i would love that in the 1000 and i wonder can the mpc 1000 do midi dumps to accomadate my s3000 (non xl). also what about the multi program use 9which may not matter to me i had a 2000(non xl) and just loaded what ever programs and pick the sounds i wanted and gave the program the songs name. are ther anyother things that 2kxl had that the 1k doesnt have or vice versa. if not im gonna get the 1k until i can afford the 4000. and is it possible to get akai to upgrade to certain features by asking them?
