i'm just getting started with midi...have been creating tracks with fruity loops using my mouse and think its time to step up to a midi keyboard/control interface type thing. i was wondering what is recomended around here as a good beginner keyboard. i was thinking for springing for a 500 dollar yamaha i found at best buy but i dont have midi on my m-audio mobile pre soundcard so usb is pretty much needed. and midi control is probably more important to me right now than an actual keyboard. ive been looking around at musicians friend and zzounds and have found a few different cheap m-audio models...such as the oxygen 8..the o2, the radium, and keystation. they are all around 100-150 dollars and i cant tell the difference between any of them really besides number of keys. i would probably prefer a 49 key one, but the compact size of the 25 keys are also appealing..so either one i would be fine with. i'm just looking for a decent quality. also i hear of a couple other brands that make good inexpensive ones. any recomendations? i'd appreciate it.
