Hammer...i would agree with you about the microarranger....just bought one last week and already used it with my mox8 on a single gig...my duo i use a yamaha psr s910 with a pa50sd...i find i get along find with the small keys especially playing organ tones on the microarranger...I'm waiting to see when the pa600 comes in i'll probably trade the pa50 in on it since the microarranger offers the same styles and sounds...stevec
