Synthesizers

Six Sines – small synthesizer

Six Sines is a compact software synthesizer built around audio-rate inter-modulation.

It uses a six-operator architecture that blends phase modulation and digital ring modulation techniques, with a flexible design that gives each part of the signal path its own modulation possibilities. The result is a synth aimed at sound designers who want deep control over evolving, metallic, glassy, and experimental tones.

This is free and open source software.

Key Features

  • Six-operator synthesis engine with feedback and routing from each operator to subsequent operators.
  • Supports both phase modulation and digital ring/audio-rate amplitude modulation within the synthesis matrix.
  • Each modulation node has its own per-voice envelope and LFO for detailed sound shaping.
  • Offers polyphonic and monophonic operation, along with a per-key piano-style retrigger mode.
  • Includes settings for MPE, mono mode, pitch bend depth, and oversampling control.
  • Provides screen reader support and accessibility features for navigating its large interface.
