I am looking into buying a MIDI/USB controler keyboard with knobs? Any suggestions either 49 or 61 note. I have looked at Ediorl, Evolution and MIDIMAN all seem good but I am having diffcluty decideing which one too buy? I know Midman's oxygen 8 is cheap but it has a small keyboard, and the pitch bend knobs are on the top of the front pannel not on the left side of the keyboard. Also will the work with any virtual synth?
