Bitphase documentation
Bitphase is a modern web chiptune tracker for creating music on retro sound chips. Compose for classic AY systems, NES, or SAA1099, and mix chips in one project. The flexible project structure lets you layer chips the way real hardware does, or invent a combination of your own.
Open the tracker at bitphase.app or build the app yourself (see how here).
