Ok... I gotta get in on tis too....
Korg (of course) Oasys 88 key as a controller
PA1x-pro as the arranger (already have that)
OpenLabs Neko for use in the studio
This set up I could use the 2 Korgs as the live set up and then set them up next to the Neko in the Studio.
I think that would be ultimate....
Don't know about a mixer or other outboard gear......
