29 Pro 2 Operation Manual Filter Envelopes 1 & 2
A: The gate generated by pressing, holding, and then releasing a key
(or through use of the sequencer or arpeggiator).
B: Corresponding DADSR envelope behavior with Delay on and
Repeat off.
C: Behavior of the same envelope with Repeat on.
Amount: -127...127 —(In the
env amount
tab in the display) Sets the
amount of modulation from the filter envelope to the filter frequency. The
modulation amount can be positive or negative, allowing for inverted
envelope control.
The cutoff frequency setting may limit the effect of the envelope on the filter. For
example, on Filter 1, if F
requency
is all the way up, a positive envelope amount will
have no effect on the filter since the filter is already completely open.
Velocity Amount: 0...127 —(In the
env amount
tab in the display)
Enables keyboard velocity to modulate the
filter envelope amount
. It
doesn’t use keyboard velocity to directly control the filter cutoff. To do
this, see the note below.
To create a program in which velocity controls the filter cutoff, turn filter enve-
lope
amount
down and turn
velocity amount
up. To achieve the best results, it may be
necessary to set an initial level using Envelope Amount. Just remember that once
Envelope Amount is set to the maximum, no modulation from velocity—or any other
source—will cause the filter to to go higher than that.
