In my first post I tried to explain the 4 signals.
1. Dry (top white knob); applied equally to the Okto (left) and the Nøjs (right) side, hence engaged with either footswitch.
2. Okto: standard synthy octave down. It has its own volume control and a tone knob (static low pass filter) (bottom two white knobs). Engaged with left footswitch.
3. Octavia style gated fuzz: This is the spitty synthy at-pitch fuzz which produces an octave up when playing high up the neck. Has a gain, tone and level control (top three black knobs). Engaged with right footswitch.
4. Octave-down fuzz: this is basically like feeding the octaver into a fuzz in series. Has a level and tone control (lower two black knobs). Engaged with the right footswitch.
The left and right side run in parallel.
So you get series and parallel signals together.
