PATCH EDITOR
GET COMFORTABLE BY DOING
Let’s make a patch, OK? That way you’ll get a feel for how the Patch editor works, and you’ll have a much
better understanding of things when you read about the details later.
better understanding of things when you read about the details later.
The patch we're going to make will be an audio compressor. A compressor reduces the audio gain when
louder signals are input. The compressor we will build is constructed from a single “ducker” module.
Here is an excerpt from the Modules Section of this manual describing the module:
Here is an excerpt from the Modules Section of this manual describing the module:
The ducker module is the basic building block for most dynamics control patches.
It is essentially a dynamic range compressor with separate inputs for the signal
whose gain is to be processed and for the detection (sidechain) input.
By connecting sidechain to the output, a basic compressor is built. By
connecting a dry signal to the sidechain and a processed signal to the input, the
processed signal can be ducked (have its gain reduced) during louder passages
of audio.
Ducking is often used by radio talk show hosts such that the host’s audio
overrides the guest or telephone caller. Each time the host talks the caller’s
audio is dropped down such that the host’s audio is much louder. If the host
talks loudly, the caller’s audio disappears altogether.

Since we’ll be using the ducker module as a compressor, we’ll loop the
output
audio back to the
sidechain
input
. Try the following tutorial out on your Harmonizer:
To start, go to the
PROGRAM
area and load the
Thru’
program
from the
Programming
bank.
Next, go to the Patch Editor area by pressing and holding the
PARAMETER
key. We're looking at an empty slate. The only
things we see are the IN and the OUT modules, which exist in
every patch. The IN module is where audio signals come into your
program, and the OUT module is where audio signals exit your
program. In its current configuration, the DSP running
program, and the OUT module is where audio signals exit your
program. In its current configuration, the DSP running
Thru’
should be passing audio unchanged, just as the patch display
shows.
To start creating the compressor, insert a ducker module. Press
the
the
<insert>
SOFT KEY
. You will get a list of things to insert.
We want a ducker, which is in the “Dynamic” group of modules.
You can either turn the
KNOB
until you see the little arrow pointing to ducker, or you can save a little
