ATTACK
DECAY
SUSTAIN
RELEASE
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.
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.
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.
This control has two functions determined by the [SHIFT] button.
When the [SHIFT] function is
(SHIFT LED Off) this control sets the time taken for the sustain level to
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.
When the [SHIFT] function is selected (SHIFT LED Flashing) this control sets how much the selected envelope is
affected by the velocity level. Firmly struck notes will open the envelope to its maximum level whilst softer strokes
will produce a lesser result, dependent on the velocity setting. The eight VELOCITY LEVEL indicators show the
velocity setting for the selected envelope. To change the setting, first press the [SHIFT] button and then move the
[VELOCITY] knob. The indicators will show the value, as shown in the following example:
At the fully anti-clockwise position [indicator 0] there will be no velocity effect, with soft and hard notes each
producing the same, maximum result. As the knob is moved in a clockwise direction [indicators 1 to 6 ] the
envelope will open less and less when softer notes are played until, at the fully clockwise position [indicator 7] the
softest notes will not open the envelope at all. On envelope 1 this maximum setting will make soft notes sound very
quiet whilst on envelope 2 this will result in much less pitch, pulse width or filter modulation.
