OC-D2 is a mono octave divider plug-in that
generates signals one and two octaves below the original. It's based on the
popular Boss OC-2 pedal, but with many more features and customizability far
beyond what other octavers offer (both pedal and plug-in types).
Overview:
-
Control the tracking accuracy.
-
Control the oscillator tone.
-
Control the dynamic envelope.
-
Tap the audio at any stage.

Full Feature List:
-
Controls to all the typically fixed values for low-pass
filters - both on the oscillator outputs (changes tone from full square wave
to pure sine, or anywhere in between) as well as on the detection circuit (which
can fine-tune the accuracy of the octave-divider's tracking).
-
Option for two modes of operation: additive oscillators or
phase-multiplier.
-
The additive mode simply mixes in the octave down signals
(via user-adjustable levels and wet/dry balance), whereas the phase-multiplier
mode flips the phase of the key signal, following the state of the selected
oscillator.
-
In additive mode, dynamics for the oscillators can be
controlled either by a noise gate or an envelope follower, both keyed off the
input signal. In phase-multiplier mode, the full dynamics of the key signal
are retained.
-
A DC-offset switch corrects the input signal to improve
tracking on rectified or offset signals.
-
A scope displays both the key signal and the output signal,
so the user can see how the plug-in is operating, and help identify what
controls need to be adjusted in order to track more accurately or produce the
intended sound. Includes a "Scope Tuning" control to affect the zoom ratio.
-
"Listen" radio buttons allow the user to tap the audio at
any stage to hear what's happening behind the scenes, and bypass certain
sections if desired.
-
Many users of the Boss OC-2 pedal seek to add a hardware
modification that disables the output filter and dynamics sections in order to
produce a more synth-like tone. This plug-in has the capability to easily
reproduce this mod, by adjusting only a few parameters.
Included are some presets that run through the capabilities
of the plug-in.
