Getting started
The Vocoder section:
This section controls the main functions of the Vocoder which are the switching on and off of the
Vocoder, selecting Vocoder presets, adjusting the volume as well as the routing of ANALYSE and
CARRIER signals. The Vocoder section works closely with the mixer section. To adjust the separate fil-
ter frequencies of the vocoder, for example, you would use the controls of the mixer while holding
down the VOCODER-Key. With the row of Keys on the mixer, the separate tracks of the Sirius can be
routed to the ANALYSE or CARRIER signal. You select the 16 vocoder presets using the Number-Keys
1-16 while holding down the VOCODER-Key.
The Microphone connector:
The Footswitch Socket:
This socket is for connecting the goose neck microphone. The microphone is auto-
matically activated when you select one of the 16 vocoder-presets. Please note that
the microphone socket is immediately de-activated as soon as you connect a cable
to the ANALYSE-IN socket on the rear panel of the Sirius.
Although this socket is not located on the front panel of the Sirius we would like to briefly go into it
at this point.
The reason for this is that a footswitch is a so called 'performance aid' with which the sound of the
Sirius can be influenced in real time. Other performance aids are the modulation wheel and the
pitch bender.
This socket requires a footswitch with an on/off switch. The footswitch should be connected prior to
powering up the Sirius. When the Sirius is turned on it will automatically recognise the polarisation of
the footswitch. Pedals which send continuous information (for example volume pedals) are not suit-
able for connection to this socket.
Once you have found the right footswitch you can try the following:
hold down a PAD on the Keyboard and step on the footswitch. If you now let go of the note you are
holding down on the Keyboard, the sound will keep on playing until you release the pedal. This is
called a Sustain-footswitch.
The second function of the footswitch enables you to transpose arpeggios. When you step on the
footswitch while the Arpeggiator is running and stay put, the Arpeggio will continue to play out nor-
mally. When you now press any note on the Sirius Keyboard the pitch of the whole Arpeggio will
change.
