Thank you. That thought had slid by the very back of my mind...it is a usb to midi cable therefore if they are not midi sounds it ain't going out.

I do not have a 'mixer' per se but I do have a pre-amplifier and two stereo amps in the same place. Would I be able to output from the laptops stereo mini-jack to one of the pre-amp rca inputs and play through my stereo setup?

A related question would be is there a way to tell BIAB that I just want to use styles that have MIDI, and no realtrack instruments?

If I had a 'mixer'... like this:

...and that would allow me to put it together with the midi output to my (guitar) amplifier?

Thanks very much,
Jim Lee
