Cassp... just wondering if you ever play with SMFs...?

76 keys makes life a LOT easier (full piano parts, more room on splits, three zones, etc.) as long as you are not tying up your LH just playing chords in a 2 octave section...

Although these things are 'primarily' arrangers, they have close to full workstation capabilities, and unless you are a 'strict' arranger only performer, I've LONG held that ONE 76 can be as good as two 61's, and far superior to just one 61...
