Good luck programming that in SB. The last big Biamp job I wrote was about 1700 lines of S+ for a four way divisible ballroom system with 40 input plates with four inputs each, faders and bar graphs for each input... I hate the Crestron Biamp module; used it once, will never use it again. It's faster for me to roll my own in S+.

What exactly is the scope of the job? What aspects of the DSP are you trying to control, exactly?

You do not need to do anything to the box to enable control.

You may or may not see real time feedback depending on whether you use the SETL or SETLD command. You still have to parse out and scale the response either way.
