You should insert a group channel, panning modulator to one side of the group and carrier to another, experiment with synthesizer presets and similar joyful things to get usable results. If a vocoder doesn’t have an integrated internal syntheszier then setting it inside the DAW can be a bit tricky. The quality of the vocalized voice is in close connection with its carrier source, the type of sound that you choose for a carrier. The end result is a blended sound of a voice and a synth line.
A series of band pass filters analyzing the modulator signal in real time control the frequency spectrum of synthesizer sound, letting only the frequencies that are presented in the modulator to get through the filters. In vocoder vocabulary, an audio clip (usually containing human voice) is a Modulator, while the sound from the synthesizer is a Carrier. You can transform a human voice into a robotic one, or even change the pitch of a recorded voice, giving the effect of some sort of singing synthesizer. I presume you know what a vocoder is and what it can be used for. Did you know that Vocodex comes also in VST form? It’s simple, not too expensive, yet still a very effective tool for making your synth sounds pop or adding some robotic nuances to your music.
