BV512 VOCODER582
D Connect the gate outputs on a Redrum to individual band level inputs.
With this connection (and no device connected to the Modulator input), the Redrum will serve as a pattern se-
quencer, opening and closing different filter bands. To adjust the gate times, set the drum sounds to Gate mode
and use the Length parameter. The result is totally different from using the audio signal of the Redrum as modu-
lator.
The vocoder bands are now solely controlled by the gate signals from the drum channels - the modulator input isn’t used.
Note that you can use a Spider CV Merger & Splitter device to split a gate signal, sending it to several bands. Also, note that the
velocity of the programmed drum notes govern the level of the corresponding filter bands.
“Playing” the vocoder from a MIDI keyboard
! To route MIDI notes to the BV512 in Reason Rack Plugin, you need to put it in a Combinator and turn on "Re-
ceive Notes" in the programmer (see “About the Receive Notes/MIDI Performance Controller check boxes” in
the Combinator chapter).
If you have routed MIDI to the BV512, playing notes from C1 and up will control individual filter bands. For example,
in 16 band mode, C1 controls band 1, C#1 band 2 and so on up to D#2 (which controls band 16).
• The level of the bands is proportional to key velocity (how hard you play).
• A band will be “open” until you release the corresponding key.
• Bands to which you have connected a CV signal (using the individual band level inputs on the back panel) will
not respond to MIDI keys.
Note that with this function, you “play the modulator bands”. However, you still need both a carrier and a modulator
signal to get any sound. Typically, you would first record the notes or chords for the carrier device in the sequencer,
then create a sequencer track for the vocoder and “play” it from your MIDI keyboard while playing back the recorded
carrier notes and at the same time inputting a signal on the Modulator input.
q An interesting application of this is to patch the vocoder as an insert effect for the whole mix (the output of the
main mixer connected to the carrier input), and “play the vocoder” while inputting a signal on the Modulation
input. Only the frequency bands for which you press keys will be attenuated. Use the FFT (512) mode for best
results.
