results, the sound of the Carrier should be similar to that of the human voice. Safe bets are the Sirius-

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.
Tip: 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).
Using other external sound sources for the Vocoder:
It can of course be very interesting to send sounds other than speech or singing through the
microphone into the Vocoder. The Sirius offers the tempting option of also including your other
audioequipment in the Vocoder. So you also just bought a full Stand-Alone-Vocoder!
