BV512 VOCODER

214

BV512 parameters

On the front panel of the BV512 Vocoder, you will find the following parameters

and displays:

| Parameter | Description

Bypass/On/Off

switch

In Bypass mode, the carrier signal passes through the de-

vice unaffected and the modulator signal is disregarded. In

On mode, the device outputs the vocoded or equalized sig-

nal. Off mode cuts the output, silencing the device.

Level meters Show the signal level of the carrier and modulator signals,

respectively.

Band switch Selects the number of filter bands (4, 8, 16 or 32) or FFT

(512) mode.

Equalizer/Vocoder

switch

Determines whether the BV512 should work as a vocoder

or an equalizer. In Equalizer mode, the Modulator input is

disregarded (see page 213).

Modulation level

display

The upper display shows the spectrum of the modulator

signal.

Frequency band

level adjust

The lower display allows you to adjust the level of each fil-

ter frequency band, by clicking and dragging the corre-

sponding bar. In vocoder mode this affects the vocoded

sound. In equalizer mode, this is where you cut or boost

frequencies. To reset a band to ±0 dB, press [Command]

(Mac) or [Ctrl] (Win) and click on its bar in the display. To

reset all bands, select “Reset Band Levels” from the device

context menu.

Note: when FFT (512) mode is selected, each of the 32

bars in the display corresponds to several frequency

bands, with bars to the right in the display controlling pro-

gressively more bands (due to the FFT bands being linearly

distributed over the frequency range).

Hold button Clicking this button “freezes” the current filter settings.

While the button is lit, the modulator signal doesn’t affect

the sound - the carrier signal is filtered with the settings as

they were the moment you activated Hold. Click the button

again to turn off Hold. Hold is also automatically reset

(turned off) when you stop sequencer playback - just like

the pitch bend and modulation wheels on synth devices.

This function can be controlled via CV or MIDI, for sample

and hold-like effects.

The Hold button is not available in Equalizer mode.

Attack This is a global attack time control, affecting all envelope

followers (see page 210). Normally you probably want this

set to zero, to make the vocoder react as quick as possible.

Raising the Attack time can be useful for “smearing”

sounds, creating pads, etc.

Not available in Equalizer mode.

Decay Similarly, this controls the decay time for all envelope fol-

lowers, i.e. how quick the filter band levels drop. Adjust this

according to taste and context.

Not available in Equalizer mode.

Shift Shifts the carrier filters up or down in frequency, drastically

changing the character of the vocoded (or equalized)

sound. This parameter can be controlled via CV, for

phaser-like sweeps and special effects.

HF Emph

(High Frequency

Emphasis)

Boosts the high frequencies in the carrier signal. This is

sometimes desired to get a clearer vocoded sound. The

reason is that a carrier signal should theoretically contain

roughly equal energies in all frequency ranges for best re-

sults - in a typical synth sound the high frequencies are of-

ten weaker than the low frequencies. Raising the HF Emph

control will rectify this.

Not available in Equalizer mode.

Dry/Wet Determines the balance between modulator sound (dry)

and vocoded sound (wet). To get the pure vocoder sound,

set this to wet (turned fully right).

Not available in Equalizer mode.
