In the example, the Cut(off) frequency of the filter 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 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; Cutoff 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 influence 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 Cutoff can reach values between 0.70 and 0.90, depending on the value being sent by
CtrlA.
Another example:
Cutoff is again set to 0.50, Env1 now drives the value down to 0.25, and a maximum CtrlA
value reduces the Cutoff frequency down to 0.
The example below illustrates the simplicity and speed of Ultrabeat modulation options:
In this example, the modulation intensity of Env1, which affects Cutoff, is controlled with
the dynamics of the performance (Vel). The secondary via modulation also controls its
direction. Try this setting in Ultrabeat to create some interesting sounds.

This section outlines the creation of mod (and via) modulation routings. The following
applies to all parameters that offer mod (and via) modulation options.
