A harder algorithm-8 target exposed that feedback must be delayed recursion in Faust, not a direct cyclic self-reference. Static DX7 output-level approximation helped import/rebuild math but was mathematically wrong for carrier amplitude. A single-carrier Dexed sweep shows carrier amplitude follows 2^((outputLevel - 99) / 8). Isolated two-op DX7 FM maps full-level modulation to Aquarium route index 6.275; summed/cascaded algorithm-8 branches now use 6.0 after PRC listening, a project-authored combined stack probe, and split cascade/summed-pair probes showed lower values were under-bright. Feedback lowers through a fitted table instead of PRC-local constants; ANLGSYN 1 showed max feedback value 7 needs a hotter Aquarium amount 2.2 to recover buzzy high bands, while value 5 remains 0.19 for PRC. ANLGSYN 1 then exposed a sustained-buzz gap: output soft clip helped but did not stop mid-note drift; max-feedback source operators need an applied-envelope sustain floor so the feedback loop stays driven after the attack. ANLGSYN 1's remaining beat is pitch LFO: AMD is nonzero but all operator AMS values are 0, while PMD/PMS lower cleanly to operator-graph vibrato with faded delay. Ratio-mode detune belongs in operator frequency lowering. DX7 voice transpose belongs in graph base frequency: transpose 24 is neutral, transpose 12 lowers MIDI note 60 to 130.8128 Hz. DX7 fixed-frequency operators are absolute Hz, not note ratios; ANLGSYN 1 proved fixed op1/op3 must lower to ratios around 0.007615/0.009227 against a 130.8128 Hz graph base to preserve low buzzing modulation. ROM COM carrier compensation was cut: user listening found no-COM renders harmonically closer and mainly too quiet, so `OperatorOutputCompensation` returns unity and graph gain owns loudness recovery. Operator key-scaling and rate-scaling must lower against the effective played MIDI note after transpose; hardcoded MIDI 60 made RES SYNTH1 too soft on attack and Piano Bass less harmonically accurate. Project-authored Dexed patch rendering now gives lawful calibration targets. Reusing the operator output curve for EG levels was tested and cut because it failed hard-target log-mel; later output-level-dependent and naive traced-release applied-envelope experiments were also cut because they worsened broader parity. Direct envelope tracing shows current linear `env=rl` cannot express DX7 EG spike/drop behavior. Dexed-style audio samples EG once per 64-sample block and interpolates applied gain, so raw EG parity alone is not audio parity. Staged operator envelopes now support linear/exponential segments and supranormal levels. `ApproximateAppliedRateLevelEnvelope` uses that surface and now picks the first near-peak before gate so slower rising modulators hit early instead of swelling late; it can also preserve a floor for max-feedback source sustain. Community gains with no COM and played-note scaling: Mooger 0.75, Piano Bass 0.72, RES SYNTH1 0.75. Algorithm-2 non-carrier applied envelopes currently cap the first peak at 0.92 to prevent ANLGSYN 1/RES SYNTH1 peak blowout while preserving Piano Bass. MELLOWSOLO is a pressure artifact test, not passing parity; its render window is 1.25s so the candidate release is audible instead of cut at the artifact boundary. Mooger needs a more aggressive attack contour, and RES SYNTH1's phase-like attack issue is likely relative operator attack/peak shape because oscillator sync is enabled. PRC remains passing on log-mel/envelope/RMS, with score floor lowered to 0.74 after rate scaling changed the aggregate score.",

Upstream Zyn presets live in a nested GPL instrument-bank submodule and may be used as test-only parity/pressure feedstock once provenance is recorded.

Zyn build fixes belong in `tools/zyn-reference/patches/` and apply to ignored artifact copies, not the clean pinned submodule. The PAD oracle now renders both generated PAD sample tables and note audio through Zyn `PADnoteParameters`/`PADnote`; optional parity artifacts live under `artifacts/parity/zyn-pad-reference` and `artifacts/parity/zyn-pad-fixtures`. The first project-authored PAD comparison proved the harness and showed Aquarium `spectrum` was not a close Zyn PAD emulation. User listening identified Zyn as pure wineglass and Aquarium as angry bees. Cutting unearned air/noise/drive/soft-clip from the rebuild, adding interpolated wavetable reads, and raising Aquarium spectral tables to Zyn's 131072-frame PAD size improved the report.

Using Zyn's reported sample basefreq 77.7813 while playing 261.6256, removing gratuitous spread/vibrato, collapsing two same-note PAD voices into one coherent spectral table, and trimming gain improved the report to log-mel 0.35669, envelope 0.347572, RMS ratio 1.001704, centroid ratio 1.004072, score 0.6211. The first PAD fixture survey shows `pad-pure` and the old `pad-texture` render identically through Zyn, so the filter/category XML in `pad-texture` is not live pressure for this oracle path. `pad-harmonic` changes the source table and note output through explicit OSCIL harmonics, making it the next real PAD reference rung.

"status": "Initial ZynInstrumentReader parses plain XML and gzip-compressed .xiz-shaped XML from project-authored fixtures into ZynInstrument records and ReferencePatch features. First Zyn-style AquaSynth rebuilds exist for additive lead, PAD texture, and vocal/formant layer. `ZynInstrumentSurvey` can rank .xiz directories by feature pressure. Named `layer` declarations provide the first Zyn-driven DSL abstraction; additive `harmonics`, PAD `spectrum`, and staged `env=rl` voice envelopes now attach to those layers. Zyn PAD `spectrum` banks can now carry explicit `zyn_mode`, `zyn_bandwidth`, `zyn_bwscale`, `zyn_profile`, and `zyn_position` table-generation fields, and `PadSynthWaveform` lowers those through Zyn-style profile/bandwidth math. The pinned Zyn source now builds as a test-only MSYS2/MinGW oracle through `tools/zyn-reference/build-zyn-reference.ps1`, which patches an ignored artifact source copy, proves `PadNoteTest`, and builds `ZynPadReference`.",

"lesson": "Start Zyn as structural classification, then move into explicit scoped rebuilds. Upstream Zyn presets live in a nested GPL instrument-bank submodule and may be used as test-only parity/pressure feedstock once provenance is recorded.

Zyn build fixes belong in `tools/zyn-reference/patches/` and apply to ignored artifact copies, not the clean pinned submodule. The PAD oracle now renders both generated PAD sample tables and note audio through Zyn `PADnoteParameters`/`PADnote`; optional parity artifacts live under `artifacts/parity/zyn-pad-reference` and `artifacts/parity/zyn-pad-fixtures`. The first project-authored PAD comparison proved the harness and showed AquaSynth `spectrum` was not a close Zyn PAD emulation. User listening identified Zyn as pure wineglass and AquaSynth as angry bees. Cutting unearned air/noise/drive/soft-clip from the rebuild, adding interpolated wavetable reads, and raising AquaSynth spectral tables to Zyn's 131072-frame PAD size improved the report. A later pitch/drone pass split PAD table root from playback note frequency: `spectrum root=...` owns table/base frequency and `freq=...` owns the played note.

Ghost Ensemble now expands its power-base multi-harmonic OscilGen source, applies Zyn filter note tracking from `freq_track`, emits `lpf_q` from the Zyn analog filter `q`, and preserves low-pass slope by cascading resonant Faust stages according to `lpf_order`; latest Ghost log-mel is 0.369402, envelope distance is 0.363685, RMS ratio is 1.054875, centroid ratio is 1.006808, and score is 0.57229.

ZynPadReference has test-only `harmonics` and `selected` modes; selected roots are diagnostic/source-specific, not a global default, because global selected roots regressed accepted DoublePadBass. sin2x remains loud/concentrated after the one-based filter-index fix, so do not claim full Zyn PAD parity until broader OscilGen filtering/waveshaping/adaptive-harmonic behavior and note/global filter LFO ownership are mapped or deliberately excluded."

- Additive `harmonics` declarations own authored ratio/gain partial banks under named layers. They lower to ordinary voices for now; do not pretend this covers Zyn ADDsynth phase, bandwidth, oscillator shaping, or free-envelope semantics.
|

- Normal voices may use staged `env=rl` rate/level envelopes. Notes still own gate timing; envelopes own level shape. This is not arbitrary Zyn free-envelope point editing.
|
||||
- PAD `spectrum` declarations own authored partial clouds under named layers and split table root from playback pitch: `root` is source/base frequency, while `freq` is the note played by the spectral voice. They generate PADsynth-style FFT wavetables with frequency-domain spreading and deterministic random phase, then emit Faust table readers before ordinary voice treatment. Richer PAD table shaping uses neutral `pad_mode`, `pad_bandwidth`, `pad_bwscale`, `pad_profile`, and `pad_position` syntax. The parser may accept older `zyn_*` parity-artifact aliases, but generated/authored `.aqua` should not expose reference-synth names for general DSP intent. Do not pretend this covers every Zyn OscilGen modulation/waveshaping/filter/adaptive-harmonic path yet.
|

- Zyn OscilGen oscillator filters use one-based harmonic indices: first harmonic is `1`, not `0`. Preserve that index when translating filter types or spectral peaks move to the wrong partial.
|
||||
- Zyn PAD analog high-pass filters are filter authority too: HP1/HP2 type, stages, and FILTER_ENVELOPE motion lower through `hpf_order` and `hpf_env=rl`, not ad hoc layer gain or brightness compensation.
|
||||
- Zyn PAD selected table roots are not a global default in Aquarium lowering. Keep sample-0 roots unless a source rule earns the selected root; currently OscilGen shift-base sources (`base_function=7`) may use the selected note table root because Organ Choir proved sample-0 roots leave the octave voice misaligned.

- Zyn OscilGen base-function modulation is source-table authority: apply it as phase modulation before base-function sampling, not as later oscillator modulation or filter/EQ compensation.
|
||||
- Zyn adaptive harmonics remap the prepared oscillator spectrum at the PAD table root frequency before PAD bandwidth/profile spreading. Do not skip it for sources whose wind/body character depends on sparse remapped harmonics.
|
||||
- Filter damping is first-class: `lpf_q`/`lpq` owns explicit low-pass Q when a reference synth exposes analog filter damping. Low-pass order remains slope authority even when Q is present; Faust lowering cascades resonant low-pass stages instead of replacing order with one generic resonant filter. Do not fake Q by secretly moving cutoff, slope, or layer gain.
