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.   
 
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: 
 
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 
Thru’ 
should be passing audio unchanged, just as the patch display 
shows.   
 
To start creating the compressor, insert a ducker module.  Press 
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
