🎵 Music & Sound Design · plugin preset sharing

Patchbay · x402

A metered sound-design marketplace where DAWs pull verified .fxp and .adg presets directly from a Base-backed vault. Instead of bloated subscriptions, producers pay a 0.01 USDC micro-transaction to preview or commit to a preset. Top-rated sound designers earn continuous royalties as their signature patches are 'called' by AI generators or human composers in real-time.

The primitive.

full primer →

Access to the plugin preset sharing 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 turning presets into pay-per-use assets, we eliminate the friction of $50 preset packs. $0.01 is a negligible friction for a 'perfect' snare sound, but creates a high-velocity revenue stream for creators when integrated directly into the producer's workflow via x402.
