Chapter 24 Ultrabeat 375
Back to the example; the frequency of the filter is set to the mean value of 0.50. When
the Mod source Env 1 enters the equation, the Env 1 envelope generator drives the Cut
value up from 0.50 to 0.70 (during the attack phase) and back down to 0.50 (during the
decay phase).
Note: You can view the exact values in the help tags that appear when you grab the
individual handles of various parameters.
If the Via source Ctrl A is introduced, the following interplay occurs: when Ctrl A
remains at its minimum value, nothing changes (yet); Cutoff continues to be
modulated between values of 0.50 and 0.70 by the envelope. A maximum value for Ctrl
A causes the envelope generator to vary the parameter between the values of 0.50 (the
mean value) and 0.90 (the Via amount).
You can see, at a glance, 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.
Here’s 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.
Here is another example that illustrates the simplicity and speed of Ultrabeat’s
modulation options:
In this example, you won’t just be changing the modulation intensity of Env 1 (which
affects Cutoff) with the dynamics of your performance (Vel), but you’ll also control its
direction as well. Try this setting in Ultrabeat to create some extremely interesting
sounds.
