The ASR Page
ASRs are three-section unipolar envelopes—attack, sustain, and release. The PC3A’s ASRs can be
triggered by a programmable control source, and can be delayed. ASR1 is always a local control.
ASR2 is local by default, but becomes global if the Globals parameter on the COMMON page is
set to On. ASRs are frequently used to ramp the depth of pitch or amplitude in a vibrato or
tremolo, enabling delays in those eects. The ASR page consists of two rows of ve parameters,
one row for each of the ASRs.
Parameter Range of Values Default
Trigger Control Source List Off
Mode Normal, Hold, Repeat Normal
Delay 0 to 30 seconds 0 seconds
Attack 0 to 30 seconds 0 seconds
Release 0 to 30 seconds 0 seconds
Trigger
This denes the control source that starts the current layer’s ASRs. The ASR starts when the
trigger switches from o to on. If the Trigger parameter is set to ON, a global ASR starts running
immediately when you select a program that contains it. A local ASR starts running as soon as
you trigger a note in the layer that contains it. Switch controls are better suited for ASR triggers
because of their binary (on/o) nature. A continuous control will trigger the ASRs when its
signal value is above its midpoint.
Mode
This parameter sets the sustain section of the ASR. The ASR’s mode determines what the ASR
does when it nishes its attack section. If the Mode parameter is set to Normal, the ASR will run
directly from its attack section to its release section (no sustain). At a setting of Repeat, the ASR
will cycle through the attack and release sections, then loop forward and cycle through again
until the ASR’s trigger switches o. If the mode is set to Hold, the ASR maintains its position at
the end of the attack section until the ASR’s trigger switches o. The ASR then goes into its
release section. If the ASR’s trigger switches o before the attack section is complete, the ASR
goes directly to its release section.
Delay
When the ASR’s trigger switches on, the ASR will start immediately if this parameter is set to
zero. Nonzero values will cause a corresponding delay between the ASR trigger and the start of
the ASR.
