Updated to Rev 1.
This is a hack that uses the stand-alone StreamByter to feedback selected MIDI messages to the input to enable advanced control relationships that are not otherwise possible.
With the feedback, you can construct logic that takes in to account and affects control settings, MIDI input and output.
The layout has examples of new constructs possible with this feedback.
The pdf explains the hack and provides logic and annotated StreamByter code for the examples.
This layout also requires stand alone StreamByter, MIDI Fire, or another MIDI routing and filtering app.
