AquaSynth Instructions

Purpose

AquaSynth is the C# authoring and compiler front-end for AquaSynth synth patches. It owns patch graph models, terse patch scripting, SFXR-derived patch mapping, analysis/scoring tools, preset catalogs, and Faust source/code generation for the AquaSynth/Vortice engine path.

The AquaSynth-rs branch may remain a reference lab and audio renderer. This repo should not depend on AquaSynth-rs for reusable authoring, analysis, preset, or Faust compiler behavior.

Persistent State

  • state/map.yaml is the canonical repo map.
  • state/spine.yaml is the rehydration spine for multi-agent synth library work.
  • state/memory.json stores durable project taste, doctrine, and decisions.
  • state/scratch.md is disposable current-slice working context.
  • state/evidence.jsonl stores short lessons that should change future work.
  • docs/audio-doctrine.md is the live doctrine for DSP, realtime audio, and patch-language design.

Update these when the synth learns something durable. Delete stale guidance instead of stacking little commemorative plaques in the hallway.

Operating Doctrine

  • Keep the audio work in this repo self-contained. External Faust is a compiler target, not an excuse to hide local contracts.
  • Authoring code may allocate, parse, search, score, and explain. Generated DSP and runtime-facing code must assume realtime rules: no unbounded waits, no filesystem, no console I/O, no locks, no surprise allocation.
  • Treat patch scripts as a dataflow language: terse surface, explicit graph, analyzable AST, deterministic lowering.
  • Separate control-rate intent from audio-rate signal work. LFOs, envelopes, UI controls, and buses need clear rate semantics even when they compile into one Faust expression.
  • Favor block-structured reasoning. Buffer-oriented APIs should make block size, sample rate, latency, and channel count visible where they matter.
  • Keep Faust output boring and inspectable. The DSL may be expressive; emitted Faust should be stable, readable enough to debug, and easy to diff.
  • Analysis metrics are tools, not judges. Spectral and envelope comparisons catch regressions; listening, target references, and gameplay context still matter.

Verification

Use focused checks:

dotnet test

For compiler-affecting changes, make sure tests cover parse -> patch -> Faust source. If Faust is installed, validation tests should continue to pass.
