BV512 VOCODER581
• In 4 band and 8 band mode, only the 4/8 first output/input pairs are used.
• In 32 band mode and FFT (512) mode, each connection corresponds to two or several frequency bands.
This means that connecting an output to the input with the same number is not the same as using the internal sig-
nal path (no CV cable connected). You can hear this quite clearly in FFT (512) mode: connect all outputs to the
corresponding inputs and gradually remove the CV cables while listening to the vocoder sound - the sound will
progressively get more detailed.
Extracting CV from the vocoder
You can connect an individual band level output to any CV input on any device. This means you can use the vocoder
as an envelope follower, having elements in the modulator sound control a parameter in another device, e.g. an effect.
Note:
• The Attack and Decay settings on the BV512 panel affect the envelope followers, and thus the rise and fall
times of the CV signals from the individual band level outputs.
• If you are using the vocoder in a mode with many bands, but want a broader frequency range to generate the
CV signal, you can merge several band outputs into one CV signal - use a Spider CV Merger & Splitter device.
Controlling vocoder bands from an external source
Connecting a CV source to an individual band input breaks the internal connection from the corresponding envelope
follower. This way you can “manually” control the vocoder filters. Some applications:
D Connect the CV outputs for one or more envelopes in the carrier device to individual band inputs.
When you play the carrier instrument, one or more of the bandpass filters in the vocoder will automatically open,
adding an extra attack to the sound. Useful if you really want to “play” the carrier, rather than just hold a chord.
