![]() 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."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.Includes a "tuning" control to affect the zoom ratio. A scope displays both the key signal and the output signal, so the use 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.A DC-offset switch corrects the input signal to improve tracking on rectified or offset signals.Since the peaks/crests of the sine(ish) waves of the filtered key signal slow their rate of change at the point where they begin to change direction, crossing at this point instead of at the quick zero-crossing of the original waveform results in smoother transitions with less harmonics. The signal is then flipped in polarity when the peaks hit zero. Here, the key signal is DC-offset so that negative peaks sit at zero amplitude. A different version of a flipper circuit is used for this mode. Mode B is a more complex circuit, and a more accurate simulation of the original Boss OC-2 pedal. This abrupt change in direction causes additional harmonics, and results in a brassy tone (although can be filtered out). Mode A (old version) flips the polarity of the key signal directly at the positive zero-crossings. Polarity Multiplier has two modes: A and B.In phase-multiplier mode, the full dynamics of the key signal are retained. 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.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. ![]() Option for two modes of operation: additive oscillators or phase-multiplier.Both on 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).Controls to all the typically fixed values for low-pass filters. ![]() It's unique from the Boss and other pedals, and other octaver plug-ins, in that it offers: It's based on the popular Boss OC-2 pedal, but with many more features and customizability far beyond what other octavers offer. Octaver OC-D2 is available for free download via Chris Hooker’s website (11.6 MB download size, ZIP archive, 32-bit VST plugin format for Windows, made with SynthMaker).OC-D2 is an octaver plug-in that generates a signal one and/or two octaves below the original. If you’re running 64-bit Windows and want a similar plugin for your setup, definitely check out the awesome Pitchproof harmonizer effect by Aegean Music. Sadly, the plugin is available for 32-bit Windows hosts only, due to the fact that it was made with SynthMaker. Essentially, Octaver OC-D2 makes it possible to dig under the hood of your virtual octave pedal and tweak it completely to your liking. For example, the filter and the dynamics section are commonly disabled with the goal of achieving a more artificial sounding tone from a guitar. The thing that the hardware Boss OC-2 pedal is often modified by the users in order in order to enhance its sound processing potential and the Octaver OC-D2 plugin actually emulates the feature set of the standard modded version of the pedal. These tools haven’t been implement simply for the sake of having more features, though. In contrast to the hardware Boss OC-2 guitar pedal which features only a bypass switch and three knobs the volume level of different octaves, the free Octaver OC-D2 plugin comes with an arsenal of built-in tools such as a noise gate, a filter, an envelope follower and a DC offset removal module, among other goodies. ![]() Since it’s a really neat freebie tool for guitarists and music producers in general, we’re featuring it in our news section even though it’s not technically a brand new freebie release.Īnyways, the plugin’s design seems to be heavily inspired by hardware guitar pedals such as the BOSS OC-2, however the plugin version implements quite a lot of added features which are there to provide additional control over the processed signal. The plugin was actually released earlier this year (back in January), but it somehow managed to stay under the BPB freeware radar up until this point. Chris Hooker has released Octaver OC-D2, a freeware octave guitar pedal style effect in VST plugin format for Windows based digital audio workstations.
