Thanks guys...

My friend plays a Yamaha QY300,a QY700 and a PSR550...all in combination with a laptop. Also in this loop is a Digitech Vocal Harmonizer.

Bottom line is he's a steel guitar player (and a great one) who wants to be able to trigger all 4 of the above sequencer with his harmonizer.

Does he need some kind of junction midi box?

Does something like that exist?

I'm guessing his whole setup could be radically streamlined...
