CHAPTER 12. ROUTING AND I/O 165
Routing a Speech Signal
Into a Vocoder's
Sidechain Input.
Some vocoder plug-ins include a built-in synthesizer to generate the carrier signal. In
this case, the only difference from the above procedure is that the vocoder instrument is
dragged into a MIDI track. Feeding the side-chain audio input works as described above.
Layering Instruments
Suppose that we have a MIDI track containing an instrument playing a string sound, which
we would like to lubricate by adding a brass sound playing the same notes. This can be
easily done by adding a MIDI track that contains an instrument playing the brass sound and
setting its Input Type chooser to tap the string track's Post FX signal.
Using an Auxiliary MIDI
Track to Layer
Instruments.
Perhaps you wonder why this works, given that the string track's output is audio and not
MIDI. When routing MIDI in from another track, we are tapping the MIDI at the latest possible
