Modules are the magic that make the Harmonizer shine.  They are signal processing “nuggets” that are 
interconnected (via the signals discussed above).  Before we discuss aspects of the typical modules like the 
delay

 module, the filter module, the pitch shifter module, etc., we need to look at the more 

specialized IN and OUT “modules." 

Orville’s programs are loaded and run one at a time on a given DSP.  The DSP running the program 

provides the program with four channels of input audio 
(where that input audio comes from is a function of the 

routing configuration, see the Harmonizer’s User Manual).  
The DSP running the program also takes the four channels 

of output audio from the program (where it is subsequently 
sent is again a function of the routing configuration).   
 

 

The DSP7000’s programs are loaded and run on its single DSP.  The DSP provides the program with two 

channels of input audio and takes two channels of output 
audio from the program. The remainder of this manual will 

show Orville-style four channel processing, but the idea is 
the same with the DSP7000’s two channels. If you send a 

program that has more than two inputs or outputs to your 
DSP7000 from VSigfile, it will not be accepted. 
 

The input audio and output audio connections to the program are handled through 
a pair of pre-defined modules called IN and OUT.   

The IN module has up to four signals to send to the program, labeled 1, 2, 3, and 
4.  Since these signals are coming from the module, they are called 

outputs

 of the 

module.  A small amount of confusion might result because the IN module has 

outputs

.  Similarly, the OUT module has 

inputs

 labeled 1, 2, 3, and 4.  This 

difficulty is minor compared to the gain in consistency created by using the word 

output

 to refer to all signals that come from a module, and using the word 

input

 

to refer to all signals that go into a module. 
 

In the simplest of conceivable programs, the IN module’s 

outputs

 are connected directly to the OUT module’s 

inputs

 

(this is the 

Thru’ 

program in bank 0).  Normally, other, optional 

modules are inserted in-between the IN and OUT modules.   

The IN and OUT modules always remain as part of the program.
