Aah but then Gunnar if you turn off the autocomp (APC) it's no longer an Arranger Keyboard with the accent on Arranger...
And it's yet another thing again to use a sequenced or pre-recorded approach or to take it a step further and use a midi file - that really is faking it in terms of live playing - oops that'll set a few heckles rising!
Turn off the APC and correct me if I'm wrong but you've got an organ or a piano basically - is that want bands want?
