Synthesis Machines
Oscillator
General information
The Oscillator Machine exposes the same set of oscillator algorithms as the Synthesizer, but stripped of every downstream stage: there is no Filter, no Drive, no DCA, no envelopes. The oscillator output is sent straight to the Mixer at the voice's Volume level.
Use this Machine when you want a clean, raw oscillator — for example to feed an external Eurorack filter through one of the CV outputs, to use the module as a paraphonic pitch source, or simply to save CPU when the full Synthesizer chain is overkill.
Tip: because the Oscillator has no built-in envelope, the voice will sound for as long as the gate is held. Use one of the Modulators (e.g. an ADSR or a Shape sequencer) on the Volume parameter to shape the amplitude over time, or hand off to an external VCA.
Tab structure
The Oscillator Machine has fewer tabs than the Synthesizer:
- Tab 1 — OSC: Model, Frequency, Transpose, Volume (always present)
- Tab 2+ — Model-specific: shape and parameter pages of the active model. The label and number of these tabs change with the selected model.
There is no FILTER tab, no AMP tab, and no FLT ENV / AMP ENV tabs.
OSC tab
The OSC tab is identical to the Synthesizer's first oscillator page.
| Model | Frequency | Transpose | Volume |
| Select the oscillator algorithm. | Fine-tune the oscillator (±24 semitones). | Tune the oscillator in semitone increments (±48 semitones). | Output level. 100% is unity gain; up to 200% to drive the Mixer. |
When the Model is Wavetable, a "File browser" entry appears in the long-press (burger) menu of the OSC tab — use it to load wavetables from the SD card.
Models
The Oscillator shares its model list with the Synthesizer — see the Synthesizer page for the full description of each model and its parameters.
| Model | Where to find its parameters |
| Wavetable | Tab 2 (page 1) for Position / Transition / Quality; Tab 3 for Width / Phase / Transform / Depth. |
| Saw | Tab 2 — Sync, PhaseMod. |
| SuperSaw | Tab 2 — Density, Spread, Fade. |
| Square | Tab 2 — Simple<>Dual, PW. |
| Fold | Tab 2 — Fold, Decimator. |
| Fold2 | Tab 2 — Fold, Sine<>Triangle, Transform, Decimator. |
| RingMod | Tab 2 — Ratio, Twist, Timbre. |
| CZ | Tab 2 — two Wave / DCW pairs. |
| Noise | Tab 2 — S&H, Color. |
| Chip | Tab 2 — Chip Type, Param 1/2/3. |
| FM 2Op | 2-operator FM (one sine modulator + one full-featured carrier). Tab 2 — Type, Wave, Ratio, Depth + Feedback. |
| VOSIM | Vocal/formant oscillator (Utrecht 1970s technique). Tab 2 — F1 (50–5000 Hz), F2 (50–5000 Hz), Shape. |
| FM1–FM8 | 4-operator FM. Tab 2 (Type) — per-operator Type; Tab 3 — per-operator Wave; Tab 4 — Ratio; Tab 5 (when present) — Depth + Mix B<>A; Tab 6 — Feedback. |
Because there is no Drive, no Filter and no Amp envelope on the Oscillator Machine, sounds are sharper and louder than the equivalent patch on the Synthesizer at the same Volume — the signal isn't shaped or attenuated by the downstream chain.
