The Modulo is a fully analog four voice synthesizer optimized for discovery.
Its architecture of six audio oscillators, a three-stage wavefolder, and a state-variable filter moves effortlessly between precision and chaos. Two of its voices form complementary modulation pairs (hyper-modulation) while all four share a frequency-modulation network that connects them in subtle or volatile ways.
The Modulo’s illuminated buttonboard spans seven octaves and provides a tactile performance surface free of menus or presets. It also accepts 1 V/octave, gate, and velocity inputs for external control. A built-in three-band color-organ represents the signal optically, producing triggers that can drive lamps or other analog systems.
The Modulo invites the player to wander, to listen closely, and to find coherence within complexity. It’s not an emulation of the past but an analog environment for those who still believe sound is something to be discovered, not recalled.

| Function | Description |
|---|---|
| Voices | 4 (monophonic) |
| Oscillators | 6 × 4-waveform (sine, triangle, square, saw) |
| Wavefolder | 3-stage, each with dedicated LFO |
| Envelope | ADSR + delta (rate-of-change) output |
| Filter | 2-pole state-variable (low-pass, band-pass, high-pass) |
| LFO | Dual sine oscillators with mutual modulation |
| Interface | Lighted 1-octave buttonboard + 3-button octave selector (7 octaves total) |
| External Control | Gate, CV, and Velocity inputs (0–5 V) |
| Outputs | Main Audio, Individual Oscillators, 3 Color-Organ Triggers |
| Portamento | Independent per voice |
| Modulation Network | Global FM bus summing all voices; the bus output can FM each voice |
| Hyper-Modulation | Two voices feature complementary oscillators with mutual FM; together with the modulation network this forms a two-layer hyper-modulation system |
