Once you have experimented with the different Carriers you will notice that not all Carrier-sounds
are suitable for use with the human voice. In order to obtain the best results, the sound of the Carrier
should be similar to that of the human voice. Safe bets are the Sirius-waveforms SpectrAE, Mal-Choir,
SuprStrg or VS_VOICE. With some waveforms you can create brilliant and original choirs, others are
more for monophonic playing. Here again: EXPERIMENT! Check out the possibilities. Generally the
intelligibility of the voice decreases with increasing pitch because the low frequencies within the
voice are lost. The speech is generally better understood the lower down the Carrier-sound is played
on the keyboard.
: In the Edit-VOCODER menu you will find some more useful parameters which help you to
avoid feedback and to increase vocal intelligibility. Here you can also mix in the original signal of the
microphone in order to use the SIRIUS as a mixing desk with built-in effects units (see page 92).
It can of course be very interesting to send sounds other than speech or singing through the micro-
phone into the Vocoder. The Sirius offers the tempting option of also including your other audio-
equipment in the Vocoder. So you also just bought a full Stand-Alone-Vocoder!
: The use of external sound sources is only recommended once you know the basic func-
tions of the Vocoder really well.
It does not matter whether it's a synthesizer, drum-computer like the RAVE-O-LUTION 309 or CD-
player, tape player, mixing desk …simply connect the audio source to the relevant 6,3mm (1/2") jack
socket on the rear panel of the Sirius: A sound source that is to be used as the Carrier-signal should
be connected to the CARRIER-IN socket. A sound source that is to be used as the Analyse-signal
should be connected to the ANALYSE-IN. The following diagram shows an example of one such con-
figuration.
