Maybe I'll try midi moose. I don't know how to set up but I guess it's possible.

Dave,
I have two inputs on my PA80 . When working in school music classes I would have my mic in one of the inputs and my guitar in the other. Does the PA 900 not have the same?
God Bless,
Don

Hi Don,
Sadly, that PA80 was the last one to feature the guitar input. I really miss the option. The 800, 900, 3x etc all have stereo ins that work DRY as a line in, but if you want to use the harmonizer, the second input is rendered dead.
It's weird too, because when the 900 came out, the input did NOT shut off when a mic was plugged in, but the Korg people disabled that function with a quick OS update. Rumor on the street is because they wanted to make it MATCH THE MANUAL DESCRIPTION. Geeeze...

Thanks Dave! That is unfortunate. All the more reason to hang on to my PA 80. I just put it back to work in the Everly style song. I just wrote.

With my new desktop Digitech VL3D working so well I might wait for Korg's next offering.

God Bless,
Don
