MURMUR · Classic parameters

GENERATED FROM AN EXAMPLE MANIFEST

ILLUSTRATIVE — hand-authored, not extracted from a real JUCE parameter tree. murmur-app has no machine-readable parameter manifest yet (verified: no schemas/manifests-shaped JSON exists in that repo as of this audit). Engine name and role are real (murmur-app README.md, docs/DSP_ENGINE.md); exact parameter IDs, ranges, and defaults below are representative examples for generator/schema validation, not shipped values. Replace this file the moment murmur-app exports a real manifest — see the OPEN QUESTIONS in ADR-0003.

9 parameters across 3 groups.

CLASSIC

Parameter	ID	Range	Default	Auto
Osc 1 Shape Base waveform for oscillator 1: sine, triangle, saw, or pulse.	classic.osc1.shape	—	saw	no
Osc 1 Detune Fine detune for oscillator 1, independent of the sync/hard-sync drift model.	classic.osc1.detune	-50–50 cents	0 cents	yes
Osc 2 Detune Fine detune for oscillator 2 relative to oscillator 1.	classic.osc2.detune	-50–50 cents	7 cents	yes
Hard Sync Hard-sync amount of oscillator 2 to oscillator 1's cycle.	classic.sync.amount	0–100 %	0 %	yes
Analog Drift Organic pitch/amplitude drift modeling analog oscillator instability.	classic.drift	0–100 %	18 %	yes
