Connections
The back panel of the BV512 offers the following connections:
Individual band levels
These are CV outputs and inputs.
• The upper row outputs CV signals generated by the envelope followers for each frequency band.
• The lower row are CV level inputs to the individual bandpass filters through which the signal is processed (the
“vocoder filters”).
Connecting a CV signal to one of the inputs breaks the internal signal path from the corresponding envelope fol-
lower (in other words, that frequency band is now controlled by the CV signal you’ve connected - not by the corre-
sponding frequency band in the modulator signal).
• If 16 band mode is selected, each output/input pair corresponds to a separate frequency band.
In 8 band or 4 band mode, only the 8 first or 4 first output/input pairs are used. In 32 band mode, each output is
a mix of two adjacent frequency bands and each input controls two bands. Finally, in FFT (512) mode each out-
put/input pair corresponds to several frequency bands.
There are several interesting uses for the Individual band levels connectors: you can cross-patch frequency bands so
that e.g. low frequencies in the modulator signal controls high frequency bands in the vocoder, you can extract CV
signals for controlling synth parameters in other devices, you can base the vocoding on CV signals from other devices
rather than on a modulator signal, etc. See “Using the individual band level connections” for details.

Description
Shift (CV in) This allows you to control the Shift parameter from an external CV source. A sensitivity knob determines how much
the Shift setting is affected by the CV signal.
Hold (Gate in) When a gate signal is sent to this input, the Hold function is activated (see “Hold button”). Hold remains on until the
gate signal “goes low” (falls to zero). By connecting e.g. a Matrix to this input, you can create “stepped” vocoder
sounds, sample and hold-like effects, etc.

Description
Carrier input This is where you connect the instrument device that provides the carrier signal (or the device to be processed in
Equalizer mode) - typically a synth or sampler device. The vocoder can handle mono or stereo carrier signals.
Modulator input This is where you connect the instrument device that provides the modulator signal, in mono. This connection is not
used in Equalizer mode.
Output In Vocoder mode, the outputs carry a mix between the vocoded signal and the modulator signal (as set with the
Dry/Wet control on the front panel). In Equalizer mode the output is the carrier signal, processed through the equal-
izer filter.
Note that the output will be in mono if the Carrier input is in mono, and vice versa - the BV512 does not process
mono into stereo.
