promini

A highly motivated music synthesis system built on miniaudio, with Prolog as a control language. Still in very early development.

The intention is to make it easy to reason about patches and sounds.

Existing or planned features (all in stereo):

• granular synthesis ✓
  • Beads-style position-based granulation ✓
  • live recording to ring buffer ✓
  • sound/sample loading ✓
  • tempo-synced grain triggering ✓
  • pitch quantization to scales/modes ✓
  • concatenative synthesis (planned)
• additive synthesis (including noise oscillators) ✓
• live audio capture ✓
• essential audio processors:
  • bitcrush ✓
  • ping-pong delay ✓
  • reverb (Dattorro with shimmer, in-loop shimmer, freeze) ✓
  • panning ✓
  • VCA ✓
  • summing node ✓
  • crossfading (planned)
  • limiter ✓
  • 4-pole ladder filter (D'Angelo & Välimäki) ✓
  • plus miniaudio's effects:
    • delay ✓
    • various filter types ✓
• clock system ✓
  • BPM-based master clock ✓
  • routes to LFO, envelope, granular, delays ✓
  • pulse (trigger) and sync (tempo-lock) modes ✓
• comprehensive modulation system ✓
  • sources:
    • LFO ✓
    • looping envelope ✓
    • gamepad axes (sticks, triggers, d-pad) ✓
    • gamepad buttons (cycling, momentary, trigger, toggle) ✓
    • noise (with sample & hold) ✓
    • keyboard (velocity, note) ✓
    • audio buffers (planned)
  • targets: oscillator, filter, VCA, pan, delay, granular, reverb ✓
• control interface using gamepad ✓, keyboard ✓ (polyphonic synth support with voice stealing), trackpad (planned)
• SDL visualizer ✓
  • waveform, spectrum, spectrogram modes ✓
  • attach to any audio source ✓
  • multiple windows simultaneously ✓
  • auto-ranging, theme support, FFT size selection ✓
• patches, presets, and setups saved as transparent prolog clauses ✓
• sequencers (planned)
  • Turing Machine (shift register pitch sequencer)
  • Euclidean (Bjorklund rhythm generator)
• MCP integration for AI-assisted patch design and composition (planned)
