This project includes selected C and G samples. Playback transposes these samples, adjusts envelopes, filters, and adds room reverberation.
Ukulele uses nylon guitar samples with ukulele tuning and a shorter envelope.
Drums, tabla, dhol, tasha, and dholak use locally implemented percussion synthesis. Bansuri uses a harmonic and breath-noise model. These instruments do not use these samples.

Additional FluidR3 banks — 28 September 2026
Cello (cello), Electric Piano (electric_piano_1), Clarinet (clarinet),
Oboe (oboe), Trombone (trombone), Vibraphone (vibraphone),
Accordion (accordion), and Banjo (banjo).
Each bank contains C2, G2, C3, G3, C4, G4, C5, G5, and C6.
These are the distinct named General MIDI banks, not renamed copies of another
instrument. The files are original MP3 payloads extracted without transcoding
from the corresponding <bank>-mp3.js distribution.

Source SFZ remapping by kinwie; optional start-offset data from Jeff Learman.
Resonant / AppsOverFlow selected 30 anchors from A0 through C8 at recorded
velocity layers 3, 8 and 14, then converted the original stereo 48 kHz / 24-bit
FLAC files to stereo 44.1 kHz MP3 using libmp3lame VBR quality 2. Relative
recording levels and complete recorded attacks/decays are retained; no per-file
normalization, synthetic velocity layers, tail trimming or looping was applied.
Only the main struck-note recordings are included, without the library's
separate hammer, release, pedal and sympathetic-resonance samples.

The distribution trims and normalizes source notes. Resonant includes four MP3 notes and transposes, loops, adjusts envelopes, and adds room reverberation during playback.

Original concert studies and DJ arrangement — 29 September 2026
The former short melody presets and film-associated excerpts have been removed
from the offered demo library. Eight new original compositions were created for
Resonant: Glasshouse Overture, Afterglow Avenue, Paper Lantern Waltz, Copperline
Express, Monsoon Observatory, Kinetic Mosaic, Velvet Switchback, and Horizon in
Motion. Each has a 24-bar form and an instrument-specific virtual arrangement.
These are eight compositions adapted across 30 instruments, not 240 unrelated
works. The sitar arrangement uses only its available open-string pitches.

Neon Meridian is a new original 32-bar, 110 BPM composition and procedural
stereo sound design. It is generated locally as two synchronized stems: rhythm;
and bass, chords and melody. It contains no external loops or recordings.
These new note sequences, rhythms and the original synthesized DJ demo audio
are dedicated under CC0 1.0: https://creativecommons.org/publicdomain/zero/1.0/
Instrument playback and exports using the separate instrument samples remain
subject to the applicable sample licenses above. This dedication does not apply
to uploaded audio, third-party samples, or third-party compositions.

Guided lesson additions — 9 September 2026
First steps, City lights, Monsoon windows, Coastal morning, Midnight metro, and
Paper kites are new secular note-sequence exercises created for Resonant.
These original note sequences and the original studio rhythm exercises are
provided under CC0 1.0: https://creativecommons.org/publicdomain/zero/1.0/
This dedication does not change the separate sample licenses listed above.

Tabla coaching uses newly programmed, simplified versions of traditional
Keherwa (8 beats), Dadra (6 beats), and Teentaal (16 beats) cycles. Sam and khali
markers follow their common groupings. These are rhythm exercises, not songs.
Virtual stroke mappings simplify hand technique and pressure. No source audio,
notation images, or instructional text is copied from the references below.
