As we shall see, the BV512 Digital Vocoder is a great voice synthesizer. But first and foremost it is an equalizer (and a very fancy one, at that).
Insert an EQ by selecting an instrument or effect and choosing Create > BV512 Digital Vocoder (Figure 8.94).
Check the back panel to make sure that the input signal you want to equalize is going to the left/right carrier inputs and that the left/right outputs are going to your Mixer (Figure 8.95).
Set the Vocoder/Equalizer knob to Equalizer.
Use the Band Count knob to choose whether you want 4, 8, 16, or 32 equalization bands (Figure 8.96).
Play your track and drag the yellow faders in the Frequency Band Level Adjust section to shape the tone (Figure 8.97).
Use the Shift knob to shift the EQ settings up or down the frequency spectrum (Figure 8.98).
