Immersive Melodies: Winds Expansion

An addon for Immersive melodies that adds the wind section: everything sounded by pushing air down a tube, from lips to reed to pipe. Craft them, load a melody, and play — they slot into everything the base mod already does, including the melody browser, recording and imports.

Instruments

Saxophone	A reed rather than lips, and it sounds like one: a fixed formant near 1 kHz gives it the honk that survives at every pitch. Held the way a sax is held — hanging from the mouth, bell turned up.
Trombone	Bright and blaring. The tone sharpens as it gets louder, the way a real slide does when the wave steepens down the bore.
French horn	The dark end of the section. Almost nothing above 2.2 kHz, so it reads as distant even when it is right next to you.
Tuba	The lowest voice here, and the slowest to speak — a bore that wide takes a moment to get going. Nothing above 1.5 kHz.
Organ	A portative organ worked at the chest. Six pipe ranks, each with the breath of chiff as it starts. Speaks and stops abruptly, like a pipe with the wind cut.

The pipe organ

A placeable instrument, three blocks wide and three high. Right-click it to open the melody browser exactly as you would with an instrument in hand, pick something, and it plays — with its keys moving under the notes. Crouch and right-click with an empty hand to stop it. Nothing goes inside it; it has its own voice.

How the sound is made

None of these are recordings. Every sample is synthesised from a physical model of the instrument — a deliberately over-bright harmonic source shaped by fixed resonant filters, with breath noise, reed buzz, slow pitch wander and per-partial attack times so the tone brightens as it speaks. Fixed formants are what make the ear hear a body rather than a transposed oscillator, and they are how Immersive Melodies' own samples measure too.

Each instrument ships eight samples, one per octave from C1 to C8, so the mod never has to stretch one recording across the keyboard.

Fitting in

The instruments join the immersive_melodies:instruments item tag, so anything keyed off it treats them as first-class instruments. They live in their own creative tab rather than crowding the base mod's.

Requires Immersive Melodies 0.6+ for Forge 1.20.1.
