The Octasynth is more than a simulation or an attempt to imitate analog synthesizers. It is an analog synthesizer. The heart and soul of the Octasynth are two different effects, both built around the ICs commonly used in analog synthesis. The first is an octave generator that converts your guitar into three square waves. The octaves then pass through a second effect: a resonant low-pass filter. 90% of the analog synthesizer tones you know are exactly that: Raw waveforms and resonant filters.
Dynamics - The Octasynth doesn't just track the note you play. It also tracks the dynamics to control the filter. Use the DEPTH and RESONANCE controls to create punch or resonant gurgles in your face.
The way you play a note has as much effect on the sound as the note itself that you play. The filter also shuts off completely when you are not playing, to eliminate noise that occurs with other octave effects.
The Octasynth's controls are designed to produce a sound quickly. No endless fine tuning is required.
Blend - A mixer control for 3 octave voices. To the left, two octaves lower. To the right, one octave lower. In the middle, a mix of all three voices.
Depth - The range of the filter. When this knob is turned to the right, each note you play pushes the filter cutoff frequency higher. This control can be a little sensitive, especially in the lower range. When turned all the way down, the filter stays below the audible frequencies (i.e., there is no sound at all). For each audible effect, it must be turned up at least a little bit. This design allows the filter to attenuate down to the ultra-low frequencies, which can cause notes to attenuate gracefully rather than splash out.
Res - resonance/feedback for the filter. Turning it to the right amplifies the cutoff frequency of the filter. Turning it all the way to the right brings the filter closer to resonance.
Level - Total output volume.
Use with bass guitar:
The most common questions we hear about the Octasynth come from bass players. In the past we have recommended not to use this effect with bass guitar, but many bassists use it and love it.
It really meets the expectations. The pedal was designed with the guitar in mind. The pedal can go a full two octaves lower, which might be too much for the lower registers of the bass guitar.
The Octasynth is monophonic, so you have to leave your diminished 9th Jazz chords at home. The Octaynth just wants rock'n'roll!
