Poly Five 78

Poly Five 78 (VST3, CLAP, AUv2)

Poly Five 78 is a programmable polyphonic software synthesizer built around a 1978-style dual-oscillator signal path.

Each voice combines Oscillator A and Oscillator B with white noise before passing through a resonant 4-pole low-pass filter and amplifier. Oscillator A provides saw and pulse waves with hard sync, while Oscillator B adds saw, triangle, and pulse waves, fine tuning, a low-frequency range, and optional keyboard tracking.

Poly-Mod routes the filter envelope or Oscillator B into Oscillator A frequency, Oscillator A pulse width, and filter cutoff. A separate LFO offers saw, triangle, and square shapes, while Wheel-Mod blends the LFO with pink noise and routes the result to oscillator frequency, pulse width, or filter cutoff.

The eight-voice engine includes Unison, glide, separate filter and amplifier ADSR envelopes, keyboard filter tracking, a release switch, and an A-440 reference tone. The interactive panel provides 49 host-automatable parameters, a 49-key keyboard, pitch and modulation wheels, voice LEDs, filter-envelope feedback, randomization, and a scrollable browser containing 64 factory presets.

Highlights:

- Dual-oscillator subtractive architecture with white-noise mixing

- Saw, triangle, and pulse waveforms with pulse-width control

- Oscillator hard sync and multi-destination Poly-Mod routing

- 4-pole resonant low-pass filter with envelope and keyboard tracking

- Saw, triangle, and square LFO shapes with Wheel-Mod source blending

- Eight-voice polyphony, six-oscillator Unison stack, and glide

- 49 host-automatable parameters and 64 factory presets

- 49-key keyboard, performance wheels, voice LEDs, and live envelope display
