Non-custodial checkout: your wallet sends USDC directly to SeedFreq's
receiving address on Base. This page never asks for or has access to
your private key. This build targets Base Sepolia (testnet) --
see window.SEEDFREQ_CONFIG below to point it at Base mainnet later.
Each part has its own five-line staff, scrolling together in real time. A part with no hit at a moment (e.g. a bar with no snare) just shows nothing there instead of bunching up. The glowing box marks what's sounding right now, sized to how long it rings.
Click an instrument row to mute/unmute it. Your mute selection is included when you buy.
Refresh for a new random composition; its seed is logged to the console. The DEV sampler is an audition candidate, not byte-identical to the mastered full render.
Price: 2.99 USDC on Base Sepolia
