When you hold down a note on the Sirius Keyboard you automatically start the envelope generator.
During the ATTACK time the sound will increase until it has reached its maximum level. After that
the DECAY time sets in, and the volume of the sound decreases until it reaches the adjustable SUS-
TAIN-level. This level remains until you release the note, when the sound can either stop immedi-
ately or fade out. The duration of the fade-out is determined by the RELEASE time.
The VCA-EG-MACRO-control gives you access to the 127 pre-programmed envelopes. The amplifier
section also has a RELEASE-Key which automatically applies a release-time with a length value of 64
for these VCA envelopes.

The modulator section allows you to set the type, intensity, frequency and destination of the modula-
tor. Every Part of the Sirius contains a low frequency oscillator (LFO) with which you can programme
automatic pitch changes (vibrato), sound colour changes (filtersweeps) and volume changes (trem-
olo). You can also synchronise the LFO to a MIDI-clock.
This page determines the waveform used by the LFO. The following waveforms are available to you:
Sinus (SIN), Sawtooth (SWU), Inverted sawtooth (SWD), Square (SQR), Triangle (TRL) and Random
(RND).
On the following page you can set the frequency of the LFO. The higher the value, the faster the rate
of modulation. If you turn the VALUE/TEMPO-dial or the MOD-RATE-control almost all the way to
the right you can choose the resolution of the modulator when the LFO-frequency is synchronised to
a MIDI-clock (1/4 note. 1/8 note etc.).
