Note: Exact values are shown in the help tags when adjusting parameters.
As soon as a modulation source is chosen from the via pop-up menu (Ctrl A in the image below),
a movable slider appears on the mod ring. Drag this slider to set the maximum modulation value
that can be reached through use of the via source (0.90 in this example).
The mod and via controls indicate the minimum and maximum values that the modulated
parameter can attain, in comparison to the default value.
In the example, the Cut(o) frequency of the lter is set to a default value of 0.50. The mod
source (Env 1) drives the Cut value up from 0.50 to 0.70 during the sound’s attack phase and
back down to 0.50 during the decay phase.
When the via source (Ctrl A) is introduced, the following occurs: when Ctrl A is at its minimum
value, nothing changes; Cuto continues to be modulated between values of 0.50 and 0.70 by
the envelope (Env 1). A maximum value for Ctrl A causes the envelope generator to vary the
parameter between the values of 0.50 (the default Cut value) and 0.90 (the via amount).
You can see the degree of maximum inuence on basic parameters by the mod and via
modulation sources—the area between the mod and via points shows the amount that the
modulation depth can be further altered by the via modulation source. In the example, the
Cuto can reach values between 0.70 and 0.90, depending on the value being sent by Ctrl A.
Another example:
Cuto is again set to 0.50, Env 1 now drives the value down to 0.25, and a maximum Ctrl A value
reduces the Cuto frequency down to 0.
