// *** This section is a special case that is only applicable to Assetto Corsa *** //
// The on/off status of C5 (can be any MIDI signal) is read to produce a simple form
// of ABS. When C5 is on, wheels are locking so we reduce braking force, and vice versa.
// The on/off state of C5 is set by a Python script running as an AC client app, and
// uses the Python API's tyre slip values to detect wheel locking. Modification necessary
// if using real MIDI devices or multiple virtual ones. I use loopMIDI.
// Comment this section out if not using, and there are problems related to it
// (i.e., I don't know whether it *needs* to be commented out.
