The Amp Module
The Amp module is relatively simple, and has only three parameters.
Control knob Parameter Range Description
6 LFO 2 amount +/- 64.0 Sets amount and polarity of LFO 2 amplitude
modulation
7 Velocity +/- 64.0 Adjusts amplitude velocity response
8 Amp Level 0.0-128.0 Controls pre-FX level of patch
How the Parameters Interact
All three of the parameters in the Amp module work together. The LFO 2 amount and Velocity
parameters operate within the limits set by the Amp Level setting.
LFO 2 Amount
This parameter adjusts the amount and
polarity of the eect LFO 2 has on the
Amplitude of the patch. It uses the current
value of the Amp Level parameter as its
starting point.
A negative value for LFO 2 Amount literally
inverts the phase of the LFO waveform. For
example, if the LFO 2 wave is set to Saw Up, it
will behave like a Saw Down wave when the
LFO 2 Amount is set to a negative value.
The Amp Level setting also sets the upper limit
of the amplitude modulation. In other words,
a bi-polar LFO waveform will not cause the
amplitude of the patch to rise higher than the
Amp Level value. This helps prevent unwanted
clipping of the signal as it heads into the
Eects section.
Velocity
The Velocity parameter determines how much
the amplitude stage will respond to note
velocity. Negative values invert the response,
so that an increase in velocity reduces the
amplitude.
When Velocity is set to 0 there will be no
velocity response at the amplitude stage.
However, other parameters might still respond
to velocity, depending on the settings in the
Mod Matrix and elsewhere in the signal path.
As the Velocity value is increased the
amplitude will decrease if a note is played at
less than maximum velocity. What the Velocity
parameter does is create “headroom” for the
velocity-to-amplitude response.
In other words, the Amp Level parameter sets
the upper limit for the velocity response. That
way a note cannot push the amplitude of the
patch higher than the Amp Level value. This
helps prevent unwanted clipping of the signal
as it heads into the Eects section.
Amp Level
The Amp Level parameter is the boss, or
at least “middle management”; it sets the
maximum output level for the signal path
before it heads into the Eects section. This
helps prevent a situation that could cause the
Amp Level output to exceed an value of 128
and cause clipping in the Eects.
Another way to think of the Amp Level
parameter is that it can be used to
compensate for quieter or louder output from
the oscillators and lters.
