You can also control the Bands of the Vocoder with an external sequencer. All dial movements
can be recorded in the sequencer and then automated. This way you can for example create impres-
sive automatic phasing effects with the Vocoder.
You will find the filterbank-programs on the Number-keys 15 and 16. When they are used the Sirius-
Vocoder behaves like an equalizer with nine Bands. Because of the steepness of the filter you can
make both subtle sound changes
obtain some very extreme effects- filter sweeps, which only
work in the middle ranges, or impressive "formant-modulations". If you (and your neighbour) wish,
you can also mercilessly overload the filter Bands. You will get the most wonderful LoFi-sounds -
pumping bass drums, grinding HiHats, wicked 303-sounds.
There is one pre-requisite for selecting the sound source: the filterbank will only effect the Parts
which are set as the Carrier-signals. The selected Analyse-signals will not be affected.
As usual you can set the volumes of Bands 2-9 in the MIXER-panel. Hold down the Vocoder-key and
turn the controls in the MIXER-panel at the same time. Use the picture at the top of this page as a
guide. The location of the Bands you can see in the diagram below:
Let´s select basic programme no. 16 "BboostFB" (hold down Vocoder-key and press Number-key 16.
Select a Synth-Part as Carrier and for this part choose a Synth-bass (for instance C03 "Acid Mod").
The Part is now located at the entrance of the Filter bank. Now hold down the Vocoder-key and
close the dials 1-5 and 8 completely and open up dials 6 and 7. Also play with Cutoff-control and Q-
factor: Aceeeeed!
Naturally the Band volumes of the filter bank are sent and received in MIDI so that you can con-
trol the filter movements with an external sequencer.
