OK, I have the non usb version.

I have the pc version of band in a box.

What the heck do you mean use it with band in a box?

Most folks use a mixer, run the output of the virtual band, lets say drums, keyboard or piano, bass, and you on the 'horn'.

So you play along right?

That's the point of the software, to provide backing tracks.

If you want to make sheet music of what you play there are other apps for that.

I messed around with trying to play keyboards through band in a box, and with some work it's ok. But why? My Korg keyboard has better sounds. I use the internal sounds from the EWI if I play that. I mix them all and my mixer is usb so I can record on my pc without problem.

Band in a box describes what the program does. Rock Band, Country Band, jazz band, whatever. Pick other instrument, layers of them, turn them off at bar x and on at bar y. Change the drummer, change the bassist..the sky's the limit.

I suspect you need to describe exactly what you want to do and see if there is a potential match.
