Cycletron v0.1.0-alpha.11

What's new in alpha.11

Fixes

• Audio startup watchdog — if audio init stalls, you now get an error screen instead of a silent hang.
• Windows dev setup works out of the box — the frontend build commands no longer assume a POSIX shell, and a bin/lib artifact name collision warning on MSVC is gone. Thanks to fusion for the report.
• Better genre percussion — the assistant no longer pads every genre with generic percussion banks; patterns stay true to the genre recipe.

Performance (Linux especially)

• Native Wayland by default when a compositor is present — smoother frame pacing than XWayland. CYCLETRON_FORCE_X11=1 is the escape hatch.
• GPU tile painting on WebKitGTK 2.48+ instead of burning a CPU core on raster threads.
• Visualizations run at full frame rate (previously capped at 30fps when ambient), and pause entirely when not visible.

Install notes

• Windows: unsigned alpha build — SmartScreen will warn; choose "More info → Run anyway".
• macOS: signed + notarized universal build.
• Linux: AppImage / deb / rpm; Arch users can use the cycletron-bin AUR package.

The usual alpha caveats

• Click Play once to arm audio — browsers-grade WebView security requires a user gesture.
• The pattern dialect is Strudel-compatible but not full web Strudel — see docs/DIALECT.md for what differs.
• AI features are optional and off until you opt in with your own API key (Anthropic / OpenAI / xAI) or a local endpoint (Ollama, LM Studio). Keys stay in your OS keychain; prompts go only to the provider you pick.
• License: AGPL-3.0-or-later.
