BV512 VOCODER

322

12.Try the different filter band options and note the difference in sound.

13.You can also adjust the vocoder sound by clicking and dragging the bars in

the lower display.

Each bar corresponds to a frequency band, with low frequencies to the left and

high frequencies to the right. You adjust the level of a band by dragging its bar up

or down. Clicking and dragging across the bars allow you to change the levels of

several bars, much like drawing an eq curve.

The upper display shows the spectrum of the modulator signal, for display only.

D To reset a band to ±0 dB, press [Command] (Mac) or [Ctrl] (Win) and click

on it.

You can also reset all bands to zero by bringing up the context menu for the Vo-

coder device and selecting “Reset Band Levels”.

14.If the vocoder sound is “muddy” or indistinct, try raising the “HF Emph” knob

on the Vocoder.

This parameter (High Frequency Emphasis) boosts the high frequencies in the car-

rier signal.

15.Try out the other parameters if you like.

See page 324 for details.

That’s it - a basic vocoder setup!

Vocoded vocals

The most common usage for a vocoder is probably the typical “singing” or “talking

synth” sound, using vocals or speech as modulator. Since Reason doesn’t support

live audio input you cannot sing and play in real time - instead you need to use sam-

pled speech or vocals (with e.g. an NN-19 or NN-XT as the modulator device). The

procedure for this is roughly the same as in the tutorial above, but this time you need

to record or enter some notes in the sequencer for the modulator device (since the

samplers don’t have pattern or Preview playback). Here’s a quick guideline:

1. Create the carrier device.

2. Select the carrier device and create a BV512 vocoder.

3. Create the modulator device (typically an NN-19 or NN-XT sampler device)

and route its output to the Modulator Input on the BV-512.

4. Load the vocals or speech samples into the sampler device and assign them

to keyzones as desired.

For details about using sampler devices, see the respective device chapter.

5. Record or enter some notes on the sequencer track for the sampler device,

so that the vocal samples are played back where you want them in the song.

To hear the unprocessed sound of the sampler device, set the Dry/Wet control on

the BV512 to “Dry”, as above. When you’re done, turn the control back to “Wet”

to get the vocoded sound.

6. Route MIDI to the carrier device.

7. Start sequencer playback and play notes or chords on your MIDI keyboard.

The result will be the classic vocoded vocal sound.

8. At this point you may want to record the notes or chords you play for the car-

rier device.

As MIDI is already routed to the carrier device track, all you need to do is start re-

cording and play along.
