That's the thing see, if I was loading the mpc up with clips I'd made in live to arrange into a track, usually at that stage, I have no idea when or if I may need to be adding filters, efx and whatever until I come to arrange it. I'm probably gonna end up settling on a laptop to be honest, as it seems the best bet to carry on with some tracks whilst away from home.
Man, I wish there was something like the mpc around with features like some of the old e-mu samplers. I love the specs on the e-mu 4xt ultra:
32-part multitimbrality (2 sets of MIDI connections).
3.2Gb Hard Drive.
Dual 24-bit effects processors.
21 filter types.
8 Balanced analogue outputs.
Word clock & AES/EBU I/O.
240 x 64-dot Custom Backlit Display.
9 bundled CD-ROMs (over 2Gb of sounds); PC/Mac editing software.
great machine at a fair price.
$599 not so bad. http://www.ebay.com/itm/E-MU-4XT-Ultra-Sampler-Great-Shape-/371286887949
