This mpc v. mv debate is hilarious! I've only seen a handful of objective opinions from either camp, what's a potential buyer to do?!
Akai is a proven beast, which is why I really wouldn't mind buying the 2500 (5000 is to "big" for my needs) but you have to admit that the vga monitor and mouse idea on the mv is pretty goddamn slick.
The first company to implement an option for external monitor (monitors...?) mouse, solidstate drive, flexible "piano-roll" style midi editing and basic multitrack recording with resampling capability, phantom power, a trigger out or 2 for some pre-midi gear, and a DI for guitar and bass has my hard-earned cheese. Oh and plenty of outs, I have a few noise mangling boxes on the sends of my Mackie (brand name drop!) I loves me some software (
NI Reaktor 5 in particular, BOOM another one!) but I have a lot of hardware toys I like to play with and sometimes I just want to bang out some noise with out turning on the pc.
Maschine is intriguing, but it still requires a computer and all the potential distractions that come with a device connected to the interwebs.
My mc505 paired with an axiom25 is a decent enough sequencer. It's made my daisy chained goodies feel like a whole instrument, for the most part. But i'd to combine 3 or 4 pieces of kit together to clear up some space, y'know?
