EXi: MOD-7 Waveshaping VPM Synthesizer
340
PROGRAM > MOD-7: EG
The MOD-7 has nine assignable EGs, in addition to the Amp
EG. Each of these can be used as an AMS modulation source
to control a wide variety of parameters.
By default, EGs 1–6 are assigned to Output Level on VPM
Oscillator 1–6, EG 7 is assigned to Output Level on the PCM
Oscillator, and EG 8 is assigned to Filter A Cutoff.
These EGs are similar to those of the AL-1, but with slightly
simplified AMS modulation,
Sustain Level modulation, and
a new parameter: Trigger at Note-On .
8–1: EG 1
The EGs, or Envelope Generators, let you create complex,
time-varying changes to AMS-modulatable parameters. The
controls on this page specify the shape of the EG. Among
other things, you can:
• Create the basic EG shape by setting the levels and times
of each segment.
• Control the curvature of each EG segment, for subtle
control over the sound of the EG.
• Set up complex modulation of EG levels and times.
• Set up an AMS source, such as an LFO, to restart the
EG.
One thing that you can’t do on this page is to control how
much effect the EG has on the parameters it modulates. To
do that. you’ll need to adjust the AMS intensities on the
pages for the individual parameters.
8–1a: EG Reset
AMS [List of AMS Sources]
This selects an AMS source to reset the EG to the start point.
For instance, you can use a tempo-synced LFO to trigger the
EG in a repeating rhythm.
For a list of AMS sources, see “Alternate Modulation Source
(AMS) List” on page 901.
Threshold [–99…+99]
This sets the AMS level which will trigger the EG reset.
Among other things, you can use this to adjust the exact
point in an LFO’s phase at which the EG will be reset,
effectively controlling its “groove” against other rhythmic
effects.
When the threshold is positive , the EG triggers when
passing through the threshold moving upwards. When the
threshold is
negative , the EG triggers when passing through
the threshold moving downwards.
Note: With some LFO shapes, and with faster LFO speeds,
the LFO may not always reach the extreme values of +99 or
-99. In this case, setting the
Threshold to these values may
cause inconsistent behavior, or may mean that the EG
doesn’t reset at all. If this happens, reduce the
Threshold
until the EG triggers consistently.
Trigger at Note-On [Check-box]
On means that the EG will start automatically at note-on.
This is the default.
Off means that the EG will only start when triggered via the
selected AMS source. This is useful for delayed EGs, or
triggered effects such as those described below.
Note: Even when this is set to Off , if the selected AMS
trigger source is above the threshold at note-on, then the EG
will trigger instantly.
