An audio input is used to pass high fidelity audio into a module. An audio input can be connected to at
most one audio or mod output. Unconnected audio inputs are actually attached to a special “null signal”
provided by the Harmonizer's operating system. The null signal simulates a zero voltage, noise-free audio
provided by the Harmonizer's operating system. The null signal simulates a zero voltage, noise-free audio
source. Audio signals range if value from -1 to +1, or full negative to full positive. Audio inputs are always
found on the left side of modules.

(as we saw the knob modules doing in the “Custom Interface” section)
. The range of values a control input can accept may
be set by a specifier, by fixed internal programming, or even by another control input. A few notes concerning
control inputs:
control inputs:
•
Control inputs are always found on the left side of a module.
•
The value of a control input cannot change the amount of resources used by a module.
•
The existence of a control input takes up processing and memory resources. In modules with a variable
number of control inputs (like the c_switch module), reducing the number of inputs reduces the amount
of resources used.
(In such modules, specifiers control the number of control inputs.)
•
Control inputs can be connected to only one control output.

A control output sends a numerical value to another module by connecting to one of the other module’s
control inputs. A single control output can connect to any number of control inputs. Control outputs are
always found on the right side of a module.

A mod input is used to pass a high performance modulation signal into a module. A mod input may be
connected to at most one audio or mod output. Unconnected mod inputs are actually attached to a special
“null signal” provided by the Harmonizer's operating system. The null signal simulates a zero voltage,

inputs are always found on the left side of a module.
Although mod signals are high performance modulation signals, they kind of stink at passing audio signals
(they were never really meant to! Remember, they act to achieve cornerstone two - to control the parameters of modules)
. An audio signal passed
through a mod in/mod out on a module will lose fidelity. This is because the sampling rate used for mod
signals is 1/4 that used for audio signals.
(Of course if you go for that retro, “aliasing." dawn-of-the-samplers kind of sound, mod
signals might be right up your alley!)
