You need to do a one time setup (assuming you want to always use these patches).

1. From Opt|Midi Audio driver setup choose the Kurzweil K2000 from the Synthesize drop down (top right)

2. On the BIAB main screen, press the + button (next to the volume spinner). Choose the Open *.Pat button and choose the K2000 as the patch.

You are set. If you want to assign K2000 patches to a part, click on that part and press the + button. Choose your patch. The patch should get saved with the song.

To mute, use the Bar Settings (F5) at the bar of choice. Setting are in each part to mute/unmute.
