Envelope Section - Red Sound DarkStar Owner's Manual

OPERATION OPERATION

ENVELOPE SECTION

This section of DARKSTAR is used to shape the sound over a period of time with two envelopes available. The first
envelope is fixed to amplitude (or volume) and decides how quickly the sound starts, sustains and then fades away.
The second envelope can be used to control the filter frequency, pulse width or pitch modulations to alter the
character of the sound.
ENVELOPE SELECT button
This large button switches between envelope 1 and 2. When the indicator is OFF, envelope 1 will be selected.
When the indicator is ON, envelope 2 will be selected.
ATTACK
This control sets the time period for the envelope to reach its maximum after a note is played. At the fully anti-
clockwise position the response is virtually instantaneous giving a percussive edge to the sound. As the knob is
moved in a clockwise direction the time to reach maximum gradually increases giving a softer start to the sound. At
the fully clockwise position the attack time will be at its maximum.
DECAY
This control sets the rate at which the envelope falls to the [SUSTAIN] level after the maximum [ATTACK] level has
been reached. At the fully anti-clockwise position the response is virtually instantaneous. As the knob is moved in a
clockwise direction the decay duration gradually increases until, at the fully clockwise position the decay time will
be at its maximum.
SUSTAIN
This control sets the level of the envelope after the decay element is completed and until the note is released. At
the fully anti-clockwise position the envelope will continue to decay to zero without interruption. As the knob is
moved in a clockwise direction the level at which the decay ends gradually increases until, at the fully clockwise
position the sustain level will be at its maximum.
RELEASE
(VELOCITY)
This control has two functions determined by the [SHIFT] button.
When the [SHIFT] function is
reach zero once the note has been released. At the fully anti-clockwise position the response is virtually
instantaneous giving an abrupt end to the sound. As the knob is moved in a clockwise direction the release time
gradually increases resulting in a softer, more natural end to the sound. At the fully clockwise position the release
time will be at its maximum.
