I have a Titanium G4 Powerbook OSX with Garageband, Reason, and will grow into Logic. I have been shopping for a MIDI USB solution and have boiled it down to MIDI USB Keyboards or a MIDI keyboard with a Tascam US-122. The keyboards I've been researching are the M-Audio Ozone, Edirol, and Novation.
Does anyone have any suggestions? I'd like to get started with a budget of $250.
