BV512 VOCODER

325

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 follower (in other words, that frequency band is now

controlled by the CV signal you’ve connected - not by the corresponding fre-

quency band in the modulator signal).

• If 16 band mode is selected, each output/input pair corresponds to a separate fre-

quency 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 output/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 con-

trols 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 page 328 for details.

Connection

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 acti-

vated (see page 324). 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 ef-

fects, etc.

Connection

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 Equal-

izer 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 sig-

nal, processed through the equalizer 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.
