1. What is a Formant Motion?

Basically, the Formant Motion function records and saves the vocoder's
"analysis" of a changing modulator signal. This saved formant motion
data can be used to produce vocoder effects without having to vocalize
into a mic each time you perform. In its internal memory, the R3 can store
sixteen sets of formant motion data, each up to 7.5 seconds long. Vocoder
programs (programs for which the [VOCODER] button is lit) can use this
data. When the R3 is shipped from the factory, bank O (FORMANT
MOTION) contains preloaded programs that use formant motion data.
You can select and play programs from this bank to hear the formant
motion effect.

2. Recording formant motion data

[MIC] switch to XLR.
