// This effect can convert a stereo insert-only effect to a bus effect.

// To work correctly it needs 4 track channels, and the following FX chain:
//
// 1. This effect in Input Mode, which will simply duplicate track channels
//    1/2 to 3/4.
// 2. The insert-only effect, which should process track channels 1/2 only.
// 3. This effect in Output Mode, which will subtrack track channels 3/4
//    from 1/2, and output the results on channels 1/2.
