Envelope generator associated to the filter
The envelope generator associated to the filter can be adjusted with the “Attack Time”
knob for the attack time, and the “Decay Time” knob for the decay time, and the
“Sustain Level” knob for the level of sustain.
Unlike other envelope generators, there is no separate setting for the time to return to
zero. This time is the same as the decay time but can be activated or deactivated with
the “decay” switch situated on the left of the keyboard. When it is deactivated, the return
time to zero for the generator is practically zero.
The two “Keyboard control” switches allow the use of a key follow at the filter cut-off
frequency.
When they are set to the “OFF” position, no key follow is connected.
When the first is “ON”, the key follow allows the modification of the cut-off
frequency by a major third for an octave.
When the second is “ON”, the key follow is of a fifth for an octave, and when both
are “ON”, the filter cut-off frequency exactly follows the keyboard. It should be
noted the pivot note is F0.
A supplementary key follow can be connected with the modulation matrix. These two key
follows combine. The key follow connected by the modulation matrix has a maximum
slope of two octaves, which can be set with the amount knob of the matrix.
When a key follow is connected, the cut-off frequency is equally influenced by
portamento, when it is active.
5.4 THE OUTPUT VOLUME AND ITS ENVELOPE
The output level of the Mini V is managed by a voltage controlled amplifier (VCA) where
the setting changes are made with the “Volume” knob in the “Output” group of the
synthesis panel.
Setting the output level
This VCA is also controlled by an envelope generator which is set in the same manner as
the envelope generator associated to the filter.
