Using Inputs with the Vocoder Effect
The Vocoder can use either input as a Modulator or Carrier. Set up the Input sensitivity with the “Trim” parameters as shown on
page 98. Simply selecting the Program B124 Vocoder Program will assign Input one as a Modulator for the Vocoder effect.
Alternatively you can set up your own Program.
The simplest way to set up a Vocoder type program is to use B127 Init Prog as a starting point ( This example will use internal
waves as a Carrier ). Select B127 Init Prog.
Press the Vocoder button in the Effects section, then press the Menu button in the Effects section.
Go to page 2. The display shows:
Set the “Voc input” parameter ( This sets the Modulator for the Vocoder effect ) to Input 1.
Now when pressing note(s) on the Master keyboard the Input signal should be heard.
If no signal is present on the Input 1 no sound will be heard.
If no MIDI note is sent to the Nova & the Constant gate parameter is set to Off no sound will be heard & if no signal is present on
the assigned Input at the moment the MIDI Note is played then no sound will be heard.
Now all that remains to be done is adjust the Sibilance level, Sibilance type & Width parameters to suit your taste.
To assign an input as a Carrier is similar to assigning an input to an effect (actually that’s exactly what you do as the Vocoder is an
effect! ). This can be done by simply “Passing” the input to the effects. Set up the Input sensitivity with the “Trim”parameters as
shown on page 98. To connect an Input to an effects chain in Program or Performance mode simply press the Dist/EQ/Config but-
ton in the Effects section then press the Menu button in the Effects section. Go to page 5 of the Effects sections Dist/EQ/Config
menu & the display will show:
Set the "Pass to effects:" parameter to either “Input 1”, “Input 2” or “Program & Input 1” or “Program & Input 2”. “Input 1” or Input
2” settings mean only the selected Input goes to the effects on the selected Program or Part & the sound assigned to the Program
or Part is mute. “Program & Input 1” or “Program & Input 2” settings mean that the selected Input & the sound assigned to the
Program or Part go the effects.
The Carrier should be a different sound source from the Modulator & therefore care should be taken to assign ONE of the inputs to
the “Voc input” parameter ( the Modulator ) & the OTHER input to the “Pass to effects” parameter ( the Carrier ).
The Filters can be also applied to the Carrier, but to do this the input that is to be the Carrier must be assigned to an oscillator as on
page 106. Additionally the Vocoder can be "frozen" allowing the user to "Capture" the Harmonic spectrum of the Modulator & sustain
it for as long as desired. To do this set the "Sustain" parameter on page 1 of the Midi menu in the Part edit section to "Voc freeze".
Now whenever a Sustain pedal "On" message is received the Vocoder will freeze & whatever harmonic spectrum was being used as
a modulator will be sustained until a Sustain pedal "Off" message is received & then normal operation of the Vocoder will resume.
This only freezes the Vocoder if the currently selected Part is supplying the Vocoder's carrier signal ( i.e. the Part is the same as
the Vocoder's "Insert" parameter on page 2 of the Vocoder menu ).
