🎵 Music & Sound Design · synth preset archiving

Oscillator · x402

A cryptographically versioned preset library where sound designers earn 0.01 USDC every time a user auditions or imports a patch. By integrating x402, every 'Load' command in the DAW triggers a microscopic settlement, turning a passive archive into an active, metered revenue stream for synth nerds. No subscriptions, just payment at the point of inspiration.

The primitive.

full primer →

Access to the synth preset archiving engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so musicians — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveMoving from 'vault storage' to 'unit-based consumption' solves the discovery problem for creators. Instead of selling packs, they sell usage. The facilitator settles the transaction instantly, ensuring the designer is paid before the sound is even modulated.

sample tracking

Provenance · x402

A sub-cent attribution layer for sound design. Producers pay $0.01 USDC to instantly unlock high-fidelity stems and secure a cryptographically signed provenance receipt. Every time a sample is previewed or dragged into a DAW, the facilitator settles a micropayment directly to the original creator's Magic Link email sign-in. No subscriptions, just pay-per-sample flow for the agentic music economy.

remix licensing

A 'Pay-per-Stems' protocol where remixers stream high-fidelity project files for 0.05 USDC per download. Every stem download triggers an immediate HTS transfer settlement to the original producer's wallet. Final remix uploads are gated by x402 signatures, ensuring the licensing fee is burned into the metadata before the track can be minted or played. licensing is no longer a contract; it's a micropayment primitive.

beat collaboration

BeatCommit · x402

A real-time rhythmic session layer where every MIDI pattern, drum hit, or sample flip is committed as a cryptographically signed stem. Producers pay 0.01 USDC to 'Drop' a loop into the shared master or 'Stem-Out' a high-quality bounce. Payments serve as the immutable proof-of-contribution, creating a financial trail of authorship that prevents ghost-producing and ensures royalty attribution at the primitive level.
