Multi-octave synth oscillator
Dubterranea is a multi-octave pitch-tracking oscillator, capable of generating classic synthesizer waveforms in three octaves simultaneously. When combined with the Xerograph Deluxe filter, the pair form a full subtractive synthesizer, allowing a bass or guitar (or voice, saxophone, etc...) to create a wide variety of thick electronic timbres - all with an immediate, intuitive, one-knob-per-function interface.
The pedal contains two synth voices - one playing in unison with the note you play, and a second that can be switched between one octave up and one octave down. Waveforms can be selected independently for each of these voices, each with its own distinct timbre - triangle, sawtooth, square, and narrow pulse.
Additionally, there is a third voice based on classic octave-down pedals. This voice's tone is influenced by the sound of your original note, with a dedicated Timbre knob that removes harmonics at one end - for an extremely deep, smooth, almost sine wave sound - and then progressively adds harmonics at the top end, for extra gritty, harmonically rich sounds perfect for feeding into the Xerograph Deluxe filter.
A second foot switch turns the synth voices on and off, allowing the pedal to be used both as a traditional octave down pedal, and a synthy oscillator, without adjusting controls. The synth voices also have their own dedicated effects loop, so that effects can be applied only to these voices, and an entire synth chain can be switched on and off with the Synths stomp switch.
Building on the concept of the original Subterranea, the Dubterranea is an entirely new, original design from the ground up, designed in collaboration with engineer Don Stavely.
