This is a strange one, I can give the AX-48 4 stars in every category yet there are faults in the design of this, the biggest being where, as a piano player, do I put my sustain pedal? The feet get in the way and as yet, my little brain hasn't worked out a way round this (ideas are welcome). It sets up easily (after a minor scratching of head moment) feels solid and looks very cool but I would now only buy this is I were playing 1 or 2 synths and didn't need to have a piano sustain pedal under my foot all the time.
