mod knob takes you from three octaves down to two octaves up.For some, the search for the perfect fuzz is a lifelong quest. Instead of the Octasynth’s blend control which only allowed for one or two octaves down, the oct.

Manual mode: This is most similar to our original guitar synth pedal, the Octasynth, but with the most requested feature added. mod knob manually controls the octaves from several octaves down to several octaves up. In ↓ modes the output pitch will get lower and lower as you play higher up the neck. You can play up the neck forever and arrive at the same pitch whether you are playing an open low E or the high E string on the twelfth fret. When set = modes playing one octave higher will produce the same note. Shepard Tone: As you work your way up the guitar neck playing higher notes, the octave cross fade descends. The octave mod knob controls the envelope’s overall influence. The octave mod knob controls the LFO speed.Įnvelope: Playing dynamics modulate the octave cross fade. In random Mode the filter follows the LFO. In the triangle, square and double square modes the filter follows the internal ADR and the freq knob.
LFO: This is where you’ll find the chiptune sounds, especially with the square and double square wave modes. LFO modulation, envelope modulation, shepard tone, or manual mode. When in filter priority the internal ADR envelope is fixed with infinite decay time. (The same way envelope filters work) The depth knob controls how much influence the the input envelope has over the filter. Turning the knob up allows for longer decay times.įilter Priority (green marker): In green marker modes the filter follows an envelope generated by the strength of the input. This allows you to make notes decay quickly and gracefully. In these modes the filter also follows the ADR envelope at a fixed depth.

(AMP – synthspeak for modulating the oscillator output level.)ĪMP Priority (white marker): In modes with the white marker the decay knob gives you full control of the AMP decay. While lacking full external ADSR control an internal ADR (Attack/Decay/Release) envelope is generated to control the oscillator output level. Filter priority and envelopes.ĪDSR envelopes are a mainstay of synthesizers. If you keep the filter frequency low you can give your synth tones some growl. To be fair many of those filter oscillation sounds can get shrill or overbearing. They think you can’t handle so much raw power.
Most guitar synth pedals won’t let you go there. Like the MS20 the resonance knob can push the Octave Theory into oscillation. Resonant filter inspired by the Korg MS20. The Octave Theory strikes the perfect balance giving you the power to create your own sound without endless knob tweaking or (gasp!) a tedious menu driven interface. While many guitarists enjoy tweaking and honing their tone most of us don’t have that level of patience for fiddling with a matrix of interactive settings. Sometimes the weird noises weren’t the weird noises you expected. Of course, on some settings the synthesizer wouldn’t make a sound, would go into uncontrollable oscillation, or make weird noises. This gave you the power to create a wide range of sounds. With great power…Īn array of knobs covered many early 1980s synthesizers. like 8 bit chiptune sounds, classic guitar synth, super sub bass tones and the world’s first ever shepard tone guitar synthesizer. Paired with an awesome filter this creates a multitude of possibilities. So what the heck is octave modulation? The octave theory seamlessly crossfades between octaves. The first ever guitar synth with octave modulation
