That helps a lot. Montana is a guitar state and the few music stores don't have much in arranger keys. I bought the WK3700 online after reading all the good reviews. I admit i've had to change the way I play with it and I could use it as a glorified drum machine. I even took it a part to consider making a module out of it. The only high end arrangers around here are Clavinolas. Ate the top line Clavs simular to the Tryos?
