BV512 VOCODER
(RECORD+REASON)
829
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.
D Connect the gate outputs on a Redrum to individual band level inputs.
With this connection (and no device connected to the Modulator input), the Redrum will serve as a pattern se-
quencer, opening and closing different filter bands. To adjust the gate times, set the drum sounds to Gate mode
and use the Length parameter. The result is totally different from using the audio signal of the Redrum as modu-
lator.
The vocoder bands are now solely controlled by the gate signals from the drum channels - the modulator input isn’t used.
Note that you can use a Spider CV Merger & Splitter device to split a gate signal, sending it to several bands. Also, note that the
velocity of the programmed drum notes govern the level of the corresponding filter bands.
