Resonance · x402

A real-time low-latency collaborative DAW where every stems-sync and track-render is a micro-transaction. Pay 0.01 USDC to 'Open Mic' for 60 seconds of global audio-in, or meter your session to pay-per-loop. Musicians earn instantly as collaborators 'unlock' specific layers of a jam. Session logs are settled on-chain via HTS transfer, turning collaborative creative energy into a metered economy.

The primitive.

full primer →

Access to the online collaboration 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 primitiveBy moving from a subscription model to a pay-per-buffer-sync model, the app eliminates the 'leech' problem in jams. Creators are incentivized to provide high-quality input because every unlock by a peer results in an instant USDC settlement. It turns jam sessions into micro-marketplaces for loops and riffs.

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
STEMS · x402
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.
