Flyback

Flyback is a patchable synthesiser. One graph can generate both a picture and a sound. The visual path and the audio path share the same module graph and are compiled down to the same flat instruction stream.

Features

• Visual patch editor for building synth graphs by wiring modules together
• One patch generates both a picture and a sound from the same graph
• Per-pixel signal synthesis driven by coordinates and time
• Normalled sockets so common sources such as time and coordinates are present by default
• Feedback and iterative image generation via feedback modules and previous-frame sampling
• Sources, oscillators, patterns, forms, geometry, color, maths, pitch, timing, shaping, time effects, feedback and measurement modules, with presets for each
• Live preview, output settings and live recording in the app shell; deterministic export through the CLI
• MIDI input support through platform backends (Windows, macOS and Linux)
• CLI tools for rendering, checking, inspecting and bundling patches
• A text language a patch can be written in, saved as and read back from — the same instrument, as source
• Plugin-based architecture for platform-specific audio/video backends and extensions
• Patch bundles that package the patch with its referenced sample and image files
• Agentic patch authoring through a model-backed assistant that can listen, propose changes and work inside the same patch graph — over any chat-completions endpoint, or over Gemini, whose models hear the patch themselves
• Cross-platform publish targets for Windows, macOS and Linux
