I'm a guitar player. I already have a Firewire Solo, but am looking for a keyboard with weighted keys. I don't 88 keys. I played around with the M-Audio keyboards at Apple, and the 61 felt okay, the 49 felt like crap. Is there anything like the 61 key keyboard that they keep on the floor in their stores, but perhaps with better weighting? I don't want to break the bank. I do want something that I'll be happy with. I also don't want to have to buy any sort of newfangled interface for my Mac Pro, and don't want to patch through the Firewire Solo. That's for my guitars and microphones. Any and all advice about the capabilities of different keyboards is welcome as well.
