Back to the Worksong Nr 2 "Voc Grov":
When you press the ANALYSE-key the lit Part-keys tell you that the drum tracks of the Sirius are the
Analyse-signals of the Vocoder. When you hold the CARRIER-key you will see that the Synth-tracks
are selected as the Carriers. With playing the sequencer try and switch off the Analyse- and Carrier
function of each Part separately so that you can hear the original signal. This example of Vocoder-use
is somewhat classic: The pads of the Synth-Parts are rhythmatised by the Percussion- and Drum
sound, creating a rhythmic pad.
Maybe you have already tried this - the Sirius gives you the option to use a Part as
the Analyse-Signal and Carrier-signal simultaneously. Your imagination will decide how to use this op-
tion!
To use the Goose-neck microphone of the Sirius as Analyse-Signal you merely have to switch-on the
MICRO.-key on the Vocoder-panel. Press the key again and the Analyse-function of the microphone
is switched off.
If you use a microphone and an audio-unit such as a stereo system or instrument ampli-
fier, please note the following to avoid feedback problems.
- allow sufficient distance between microphone and speakers
- use the lowest possible volume-levels
- during live-performance make sure the microphone is not pointed directly towards the PA-
speakers.
Before you switch on, set the Gain-control to the right of the rear panel of the Sirius to the middle set-
ting (12 o´clock position). If you are using an audio-unit such as a stereo system or instrument ampli-
fier, turn down the volume control of the amplifier to minimum. Then turn on the microphone with
the MICRO.-key as Analyse-source and carefully turn up the volume control while you speak into the
microphone. Bring your mouth as close to the microphone as possible. Should you still not be able
to get a regular Vocoder-sound, carefully turn the Gain-control on the rear panel to the left (when fac-
ing the rear panel), until your signal is balanced. Try to avoid overloading.
The use of the human voice is particularly well suited to illustrating once more the way the Vocoder
works. First select a suitable Vocoder-basic programme, for instance Nr.2 "ChoirVoc". Turn the MI-
CRO-key on and select a Synthesizer-sound as Carrier: For example use a soft string-sound. Play a
note on the keyboard and at the same time speak into the microphone. Now play a melody. You will
hear that you can control the pitch of your voice with the keyboard. If you press several keys at once
you will suddenly sing with several voices.
This principle can be used in a different way: You can have a choir singing your lead vocal.
