You are probably already familiar with the envelope parameters. Menupage 2 shows
the envelope parameters for the filterbank amplifier. We won’t need these parameters
right now, but you should memorize that the filterbank has an additional envelope
controlled Amplifier for it's output. If the envelope amplifier bypass is not opened and
the filterbank is not triggered by the analog part, the output of the filterbank will create
nothing more than silence.
A later chapter will demonstrate how to create filterbank rhythms using noise, the
filterbank and the stepsequencer. The settings already done in this chapter are a good
starting point for this basic stepsequencer lesson. You may want to have a look into
the filterbank rhythms chapter in the stepsequencer section.
3.3.8 The envelopes of the Spectralis analog synth
In addition to the usual attack, decay, sustain and release parameters the envelopes of
the analog synth have an additional parameter hold-time, which directly follows the attack-
phase. You can get to the filter envelopes by pushing the
(EG-Depth)
button. The post
filter VCA- and VCF-envelopes of both analog filters are distributed on four parameter
pages.
As an addition to the envelope edit pages in the VCO, fixed filterbank and VCF sections,
we have created duplicates for all volume-envelope edit pages in a special envelope edit
menu located in the VCA section. Pushing the
(EG-Balance)
-button opens the envelope
edit page duplicates.
You may instantly notice an arrow symbol close to the decay parameter label. This
arrow indicates you can select an additonal menu page with the corresponding encoder
button. Depending on the selected envelope the message might look something like:
1/8: VCO1 EG
Hld:0 Byp:0
Using the additional parameter ”Hold” forces the envelope to remain at the maximum
level of the attack phase before entering the decay phase for an adjustable period of
time. This is a valuable parameter if you are trying to emulate the inconsistencies of
analog envelopes. The typical Minimoog envelopes for instance have a slight delay between
the attack and the decay phase, which can be simulated rather well with a hold value of
about 14 with the Spectralis envelopes.
3.3.9 Note priority and multitrigger settings
Monophonic synths like the Spectralis analog synth can only play one note at a time.
Depending on which note is played the pitch can be higher or lower. This is certainly not
news to anyone. What happens however, if two notes are played at the same time on
