Static Public Member Functions
static TableSet	from_rom (const RomImage &rom)

static TableSet	from_cache_directory (const std::filesystem::path &directory, const TableManifest *manifest=nullptr)
	Loads every table from a directory of extracted .bin slices.

Detailed Description

The static tables the engine needs, loaded from SCCore.dll or from a directory of extracted .bin slices.

Accessor names follow the project's symbol labels (g_amp_curve_hi becomes amp_curve_hi) so the code greps cleanly against the reverse-engineering notes. Those labels are behavioural hypotheses, not Roland's own names.

Element counts are derived from each table's byte length, not from the manifest's shape string – several shapes record a byte count where an element count would be expected (curve_level_2a00.bin is 256 bytes holding 128 uint16_t entries, yet its shape reads 256).

The set owns its bytes. Byte-typed tables are spans into that storage and typed tables are converted copies, so every view here stays valid for the lifetime of the set and none of them depends on the RomImage outliving it.

Member Function Documentation

◆ from_rom()

TableSet ts::TableSet::from_rom ( const RomImage & rom )

staticnodiscard

Loads every table by slicing the DLL at its manifest offset.

◆ from_cache_directory()

TableSet ts::TableSet::from_cache_directory	(	const std::filesystem::path &	directory,
		const TableManifest *	manifest = nullptr )

staticnodiscard

Loads every table from a directory of extracted .bin slices.

Throws std::runtime_error if a cache file is missing or has the wrong length. A length mismatch means the cache was extracted against an older manifest and must be regenerated; reading it anyway would silently misalign every table after it.

◆ operator=() [1/2]

TableSet & ts::TableSet::operator= ( TableSet && )

noexcept

◆ operator=() [2/2]

TableSet & ts::TableSet::operator= ( const TableSet & )

◆ raw()

std::span< const std::uint8_t > ts::TableSet::raw ( std::string_view name ) const

nodiscard

Returns the untouched bytes of one table; see names.

Throws std::out_of_range if no such table was loaded.

◆ amp_curve_hi()

inlinenodiscardnoexcept

g_env_shape — the fast-approach segment shape.

258 entries, and the 257th is not slack: env_ramp_segment interpolates from the entry it lands on to the next one, so a phase of zero reads entry 256. Must be interpolated, not looked up bare.

◆ env_start_phase()

std::span< const std::uint16_t > ts::TableSet::env_start_phase ( ) const

inlinenodiscardnoexcept

g_kf_tvarate1 — 128×128; TVA envelope rate key-follow for the release.

◆ kf_tvf_env()

std::span< const std::int16_t > ts::TableSet::kf_tvf_env ( ) const

inlinenodiscardnoexcept

g_kf_tvfenv — TVF env-depth key-follow.

Only rows 0–15 are used; the cache is an over-read whose used prefix matches the DLL.

inlinenodiscardnoexcept

g_kf_tvfrate — 128×128; TVF envelope rate key-follow.

Row 0 doubles as g_kf_tvfrate2, the release table, which covers 98% of partials.

inlinenodiscardnoexcept

g_porta_step — 128 entries; portamento glide in milli-semitones per control tick, indexed by the CC#5 time byte.

The glide is linear in pitch, not in frequency: 0 is instant, 64 crosses an octave in about half a second, and 127 takes two minutes over the same octave.

The curve is Chamberlin's own bound, sqrt(q^2 + 4) − q, to within 0.002 — it is neither a make-up nor a gain, despite the g_svf_makeup_gain_tbl label the decompile carries.
