yeah actually ive used reason a lot (i did maybe about 100 beats on it last year and the year before). there's something really dull about the sound of it (the spring reverb on the new reverb module is way nice tho). i love how it works but the sound quality is just garbage.
like i could take a sample i just recorded from a nice mic thru a nice mic pre, i know how the thing sounds you know? i put it into reason and it sounds dark and lifeless, even with no mixer, no fx or anything.
the mpc sounds really good to me. frequently a little bit dark, which i dont like, but the low end is so tight that i dont mind everything not being explodingly bright all the time. maybe i was just used to working on a mac where everything is super duper clean digital sounding (i did all my stuff on macs before getting the 1k). the mpc's bit grunger is really nice... using the 6 outputs and mixing from my analog mixer is getting me the best results so far, by a lot.
