Midi
From Virtools Wiki
Virtools allows for a multitude of ways to interface with the MIDI protocol. A number of developers have created BB's specifically for MIDI as well, including midi OUT from Virtools.
The simplest midi structure for a variable control surface (knob, slider) is:
Read MIDI BB (Must select "Edit Settings", and turn on, "Ask for all commands")
Link this to a Test BB. Pass the Note from the Read MIDI to the Float A Test BB. You can then pass the Attack from the Read MIDIBB to another BB post-TEST. Generally a Bezier Transform is useful at this point, to get the midi Attack into a useful format. This schematic shows a basic read-midi structure.
