OR Manual
Installation
This module is designed to be mounted within any standard Eurorack-compatible case. It
requires only 2HP of width, and because it’s a passive module, it requires no power.
Operation
At its most basic, an OR circuit looks at two or more incoming signals, and if the
voltage of at least one of those signals is high, then the voltage at its output is also
high. In Boolean logic terms, only one input needs to be “true” in order for the output to
be “true.”
Intellijel’s OR is divided into two sections — upper and lower. Each section is its own
3 IN x 1 OUT OR circuit. Plug up to three triggers, gates or waveforms into the upper
section’s top three jacks
[1]
and OR sends the OR’d result out the upper section’s
bottom jack
[2]
. Similarly, triggers, gates or waveforms patched into the bottom
section’s top three jacks
[3]
are OR’d out the bottom jack
[4]
.
The output
[2]
of the top section is normalled to the first input on the bottom section.
So if nothing is plugged into the top section’s output jack
[2]
, then OR acts as a
6 IN x 1 OUT OR circuit, where all three top inputs
[1]
and all three bottom inputs
[3]
are OR’d to a single output
[4]
.
Usage Example: Logic Functions
Logic operations are the most common use for OR circuits. Assume one gate
sequence triggers a kick sound, and a second gate sequence triggers a snare sound.
If you run each of those gate sequences through OR, you’ll get a third gate sequence
that contains a trigger every time
either
the kick
or
the snare sounds.
