I was wondering if anyone knew the controller numbers so I can select different patches. I have a Sound Blaster 16. Any help would be appreciated.
Instrument patches can be set initially with the Playback Instrument dialog (Staff menu).
Later in the staff, you can modify patches with Insert | Instrument Patch ("I" from the keyboard).
AFAIK, NWC won't let you arbitrarily set controllers, though the Insert | Multipoint Controller
lets you fiddle with volume, tempo, pitchbend, breatcontrol and stereo pan.
If you'd like to tweak other things, send a wish to the Wish List (elsewhere on this site).
