Hi Bernie,
can't see why you couldn't use it.
As you said midi out to sd2, midi in korg ( via your laptop)

I haven't used my V arranger for a while ( I mainly bought it so I could get my ketron styles into midifile format).
I'll double check, but I think you'd just set your microarranger to sequencer or single instrument mode? Can't remember off the top of my head what setting I used with my PA3x. I'll check it out when I get a chance.

You'll have a perfect little setup going there. Korg, Varranger ( ketron/psr styles) & hopefully one day soon Roland.

So far,there shouldn't be a problem as I can control vArranger with my touch screen, and KB just sending note messages. The question is how fast I can switch midi off and play MicroArranger by itself ?

Not knowing Korg well enough, I am wondering if there are too many hoops to jump in live play.
