Playing live, I get to solo a LOT, and playing a decent variety of different genres in different bands, the range of sounds they need is pretty much up there.

About the only thing I'm NOT comfortable soloing is guitar, and I'm even worse trying to emulate rhythm guitar..!

Playing these solos on an arranger, in arranger mode, is another kettle of fish. To be honest, if I can't use the bender, that pretty much rules out horns and winds, fiddle, pedal steel, and basically the large percentage of sounds other than keyboard ones (organ, Rhodes, accordion, piano etc.). If I can't bend it and the real thing DOES, I'd rather not play it at all.

In those circumstances, I'll make an SMF from the arranger output, and free up both hands. I miss my chord sequencer!
