So, I've been lusting after the illustrious Akai MPC for longer than I'd care to mention, and now I'm moving into a gaff with a decent sized studio space I thought I'd buy one! Firstly - who uses one? Which model do you use? I've been looking at the MPC500 as it's less than £350 and runs from batteries (great for my commute to work). However, I know that the MPC2000XL is the 'standard' and, according do some die-hard users, it 'feels different' to the new machines. Is there any real difference in the groove quantize, or sound of the machines? I think that you can get a decent 2000XL for about £500 from eBay; is the cost difference really worth it? NB* I don't need an all-singing-all-dancing production suite, as I use a PowerBook w/ Reaktor & Logic Pro as my main writing tools. It's the hands-on beat creation that I'm really interested in; that, and the ease-of-use in a live environment (I'm a drummer, see). Cheers, yo.
