The aMp MODule
The Amp module is relatively simple, and has only three parameters.
control parameter
range
Description
1
LFO 2 /- 64.0
Sets amount & polarity of LFO 2 effect on amplitude
3
Vel Env
+/- 64.0
Lets velocity set maximum range of Amp envelope
4
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 Envelope
parameters operate within the limits set by the Amp Level setting.
lfO 2 amount
This parameter adjusts the amount and polarity
of the effect 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 Effects
section.
Velocity envelope (Vel env)
The Vel Env parameter determines how much
the amplitude envelope will respond to note
velocity. Negative values invert the response, so
that an increase in velocity reduces the amplitude
envelope response.
When Vel Env is set to 0 the amplitude envelope
will not respond to changes in velocity. However,
other parameters might still respond to velocity,
depending on the settings in the Mod Matrix and
elsewhere in the signal path.
As the Vel Env value is increased the amplitude
will decrease if a note is played at less than
maximum velocity. What the Vel Env 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 Effects 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 Effects section. This helps prevent a
situation that could cause the Amp Level output
to exceed a value of 128 and cause clipping in the
Effects.
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 filters.
