| AM/RM Crossfader | knob | -10V – 10V | Blends between the dry wavefolder signal (left) and the amplitude- or ring-modulated copy of it (right). Fully left gives the unmodulated wavefolder output; fully right gives only the four-quadrant multiplier output.1069 |
| AM/RM Switch | switch | — | Selects between amplitude modulation (upper position, two-quadrant/unipolar modulator) and ring modulation (lower position, four-quadrant/bipolar modulator).1069 |
| Coarse Frequency (Green) | knob | 27.5Hz – 7040Hz | 1069 |
| Coarse Frequency (Yellow) | knob | 27.5Hz – 7040Hz | 1069 |
| Coarse Frequency Lock (Green) | button | — | When pressed, digitally samples and holds the Coarse Frequency knob voltage, preventing accidental detuning. The oscillator's pitch then responds only to external CV or internal FM. Press again to unlock; if the knob moved, the new position takes effect.1069 |
| Coarse Frequency Lock (Yellow) | button | — | 1069 |
| Exponential FM Attenuator (Green) | knob | — | 1069 |
| Exponential FM Attenuator (Yellow) | knob | — | 1069 |
| Fine Frequency (Green) | knob | -1semitone – 1semitone | Finely adjusts the green oscillator's pitch by more than one semitone in either direction. Not affected by the Coarse Frequency Lock.1069 |
| Fine Frequency (Yellow) | knob | — | 1069 |
| FM Deviation (Green) | knob | -10V – 10V | 1069 |
| FM Deviation (Yellow) | knob | — | 1069 |
| Frequency Scale Switch | switch | — | Selects between audio-rate and LFO-rate operation for the green oscillator. In Low mode, the frequency range is approximately 0.15–40 Hz, about 176 times slower than the audio-rate range.1069 |
| Linear TZFM Attenuator (Green) | knob | — | 1069 |
| Linear TZFM Attenuator (Yellow) | knob | — | 1069 |
| Modulation Bus Level | knob | -10V – 10V | Controls a VCA that sets the amplitude of the green sine wave (or external signal) routed to the four timbre CV inputs. Leftmost closes the VCA (no modulation); rightmost reaches unity gain routing the full green sine to the timbre inputs.1069 |
| Pulse Shaper | knob | -10V – 10V | Shapes the harmonic content of the PWM pulse wave: left emphasizes low frequencies, noon reproduces the PWM wave most purely, and further clockwise progressively emphasizes high frequencies until around two o'clock where they peak, after which low frequencies are re-emphasized with inverted phase.1069 |
| Pulse Width | knob | -10V – 10V | Sets the comparator threshold that determines the ratio between the positive and negative halves of the PWM pulse wave. Center position produces approximately 50% duty cycle (square wave). Moving left or right creates positive or negative asymmetry.1069 |
| PWM Source Switch | switch | — | 1069 |
| Square/Shaped Pulse Switch | switch | — | 1069 |
| Sync Switch | switch | — | Three-way switch on the green oscillator selects between no sync, Lock Sync, and Flip Sync relative to the yellow oscillator. The yellow oscillator's sync mode is set via a back-panel jumper.1069 |
| Triangle Shaper | knob | -10V – 10V | Morphs the yellow oscillator's triangle wave between a sine (left), triangle (noon), and logarithmic waveform (right). Output feeds both the Source crossfader and the PWM comparator.1069 |
| V/oct Integrator Level | knob | — | Routes the yellow V/oct CV to the green oscillator with a variable slew/glide time. Fully left means no signal reaches green; fully right applies the exact same voltage instantly; intermediate positions introduce glide proportional to the knob position.1069 |
| Wavefolder | knob | -10V – 10V | Controls wavefold amount. The first dotted section (leftmost to clean-waveform icon) controls amplitude from 0 to unity gain with no folding. Rotating clockwise past that point introduces progressively more folds up to the maximum at the rightmost position.1069 |
| Wavefolder Ping Decay | knob | — | Sets the nonlinear decay time of the wavefolder ping envelope. The leftmost position gives the fastest decay; turning clockwise produces a significantly longer decay.1069 |
| Wavefolder Source | knob | -10V – 10V | Crossfades between the Triangle Shaper output (left) and the Pulse Shaper output (right) as the signal fed into the Wavefolder. Noon gives a 50-50 blend; fully right retains a small amount of the Triangle Shaper signal.1069 |
| Wavefolder Symmetry | knob | — | Adds a voltage bias to the wavefolder input to create asymmetric folding between the positive and negative halves of the waveform. Noon is perfectly balanced; clockwise emphasizes positive-half folds; counterclockwise emphasizes negative-half folds.1069 |
