Section 2
Airy Choir
In this section we are going to create a “choir” sound. In reality
we will be using previous techniques to take advantage of what
we believe would make up the basics of a choir, but leave
enough room to make what
might best be called a “Vocal
Pad”.
As always, start with the Initial
Patch, and follow the Action
List shown in Figure 11.6.
With this first TONE we are
heading towards a solo voice
type of sound. That is,
something like a solo tenor
singer, or soprano.
There are some key points to
this first TONE:

singer (of course, you are always welcome to try other
waveforms).
1. We have combined some Pulse Width Modulation with a
negative Pitch LFO to create a distinctive “vibrato”.
2. We have added a very obvious “scoop” to the pitch, much like
a singer struggling to reach the notes.
3. As in the Electric Piano, from the previous section, we have
used negative envelope for the Filter.
As always, all the settings are merely suggestions. Please feel
free to experiment and search for your perfect vocal sound. In
particular, you will find that there is a very strong relationship
between the Pulse Width setting and the Cutoff Frequency.
Subtle changes can create different “vowels”.
