Compression ratio.
This algorithm is much the same as E-4 Stereo Compressor above, except that the gain reduction is
driven not by the audio signal itself, but by a side-chain input. Refer to the description of E-4 for
explanation of the common parameters not detailed below.
The Z knob/CV is the side-chain input. If you're using an audio signal here, you'll want to set the
knob to its central (un-illuminated) position first. However, you can also use Z with any CV to
control the gain reduction directly.
Parameter 5 sets the compression ratio, with a range from 1 (no compression) to infinity (effectively
limiting rather than compression).

Side-chain mix.
This algorithm implements a mono compressor with side-chain input.
X is the audio input; A is the audio output.
Y is the side-chain input, which drives the compression amount applied to the audio signal on X.
The B output provides a CV reflecting the amount of gain reduction being applied.
The Z knob/CV sets the compression ratio, from 1 (no compression) at fully counterclockwise, to
