The Vocoder
The Vocoder's 16 basic programmes can amongst other characteristics be distinguished by their
filtertype, the filter frequency and the decay-time for each of the 11 Vocoder-Bandwidth possibilities,
or 'Bands'. By the way QUASIMIDI will offer further Vocoder programmes in future.
After selecting a basic program we now feed different sounds into the Vocoder. You will soon be
convinced that the SIRIUS Vocoder is much more than just a voice mutator.
A turned off
Analyse-function
does not mean that
this PART is muted.
The PART is just
not sent to the
Vocoder anymore.
How can I
select
Analyse-
signals and
Carrier?
You already
know that the
sound of the Analyse-signal is transmuted into that of the Carrier-signal.
Four keys on the MIXER-panel decide which sources are to be fed into the Vocoder
(VocoderRouting): ANALYSE, CARRIER, CARRIER-EXT. and MICRO. The lit key indicates that
the respective sources are fed into the Vocoder. A lit ANALYSE- or CARRIER-key means that at
least one SIRIUS-part is selected as Analyse-signal or as Carrier-signal.
You have probably sensed already: The Sirius-Vocoder allows you to select several Analyse &
Carriersignals simultaneously. But most of the time you will obtain a better sound result when only
few parts are routed to the Vocoder. Like so often in music, less is more.
Caution: The Vocoder always requires sound sources on both inputs. When you have selected only
the Carrier-signal or only the Analyse-signal whilst in sequencer mode, you will not hear any
Vocoder-sound. This is also the case if Carrier and Analyse-signals are not being played out at the
same time.
Selecting Sirius-Parts as the Analyse-signal:
In order to select one or more parts of the Sirius as the Analyse-signal, first hold down the
ANALYSEkey of the VOCODER-panel. The lit keys under the dials will indicate which Parts have
been selected as Analyse-signals. While you still hold down the ANALYSE-key, turn on the key for
the Part or Parts which you wish to use as the Analyse-signal of the vocoder. That means you chose
