BV512 VOCODER

321

Setting up for basic

vocoding

This tutorial describes how to connect and use a typical vocoder setup. We assume

here that you have a MIDI keyboard connected. For details on the parameters, see

page 324.

1. Make sure there’s a MIxer device in the rack (with at least one free channel).

2. Create the instrument device you want to use for the carrier signal.

This could typically be a synth or a sampler. In this example we choose a Subtrac-

tor synthesizer.

3. Set up the carrier device for a sustaining, bright sound.

It’s important to have high frequencies in the carrier. On the Subtractor, a simple

but effective carrier sound would be based on a sawtooth wave, with the filter fairly

open. For more about choosing carrier sounds, see page 326.

4. Select the carrier device and create a BV512 Vocoder.

If you flip the rack around you will see that the Vocoder is automatically routed as

an insert effect for the carrier device (using the Carrier Input jacks).

5. Press [Shift] and create the instrument device you want to use for the modu-

lator signal.

Pressing [Shift] will add the device without auto-routing it to a mixer - this makes

sense since we want to route it to the Vocoder in this case.

For a modulator device you would typically either want a sampler (with vocals or

speech samples), a drum machine or a Dr.Rex device (with vocal or rhythmic

loops). For simplicity we use a Dr.Rex device in this example.

6. Flip the rack around and route the output of the Dr.Rex to the Modulator In-

put jack on the BV512.

7. On the BV512 Vocoder, turn the Dry/Wet knob fully to the left (“dry”).

This will let you hear the unprocessed sound of the modulator device only - useful for the next step:

8. Load a loop into the Dr.Rex device and click the Preview button to start play-

back.

For example, you could simply choose one of the Dr.Rex Drum Loops in the Fac-

tory Sound Bank.

9. Turn the Dry/Wet knob on the vocoder fully to the right (“wet”).

Now you won’t hear anything - since there is no carrier signal.

10.Route MIDI to the carrier device by clicking in the MIDI symbol column for its

track in the sequencer.

11.Play a chord or a note on your MIDI keyboard.

What you hear now is the vocoded sound, e.g. the carrier sound processed to

have the same tonal characteristics as the modulator.
