OB 12 Z-Domain Synthesizer
7. 5 VOLUME CONTROL (AMPLIFIER)
155
The amplifier controls the volume of the sound, varying it in relation to time when required. This
section allows you to set the envelope which will control the amplifier and the distribution of the
sound within the stereophonic panorama.
The Amplifier section is as follows:
•
[ATTACK]
(Attack Time)
: this slider allows you
to regulate the attack time of the amplifier
envelope, meaning the time the sound takes
to reach the maximum signal level once the
note has been played.
•
[DECAY]
(Decay Time)
: this slider allows you to
regulate the decay time, meaning the time
from when the signal reaches the maximum
level to when it reaches the Sustain condition.
•
[SUSTAIN]
(Sustain Level)
: regulates the level
of maintenance of the signal. The duration of
this segment is controlled by the Sustain Time
parameter, displayed in the EDIT FILTERS /
ADV-ENV display page (see point 8.5).
•
[RELEASE]
(Release Time)
: regulates the release time, meaning the time from when the key is
released to when the sound is no longer present.
See next the example of a typical ADSR (Attack, Decay,
Sustain, Release) envelope applied to the amplifier, which
therefore specifies how the level of the sound changes over
time:
•
[AMOUNT]: regulates the volume of the Timbre. Clockwise rotation provides higher sound
volumes. This control therefore allows you to set different volumes for the various Timbres
which make up a Program (the general volume of which can be controlled using the [MASTER
VOLUME] trimmer).
•
[LFO1 DEPTH]: this trimmer provides two specific
functions. When the LED of the [AUTOPAN] button is
on, the trimmer regulates the amount of signal which
will be affected by the Pan function. In the central
position, the sound will not move within the stereophonic
panorama. In either of the extreme positions, the sound
will be completely affected by the Pan effect and in
opposite directions (depending the chosen end of the
trimmer scale).
