Simulation Instrument Studio 1
One codebase for Windows, Mac, and Linux. Customers do not install .NET or Java. The published download is self-contained.
Simulation Instrument Studio and Simulation Panel are .NET 8 desktop apps. The window shell is Avalonia 11. Drawing is SkiaSharp. Lua is MoonSharp, one state per instrument. A panel is a layout of those instruments. Panel scales the finished picture. The instrument still draws at its own size.
Visual Studio Code is the editor. The Simulation Instruments extension supplies API completions. A Lua extension supplies syntax highlighting. F5 attaches the Debug Adapter Protocol to Studio on port 4711. A breakpoint pauses the instrument. Hover reads the Lua stack.
X-Plane is reached through the Simulation Instruments plugin, installed in the X-Plane plugins folder. It answers on 127.0.0.1 port 4730. Datarefs include ints, floats, doubles, and arrays. Commands report begin, continue, and end.
Test Pilot is the built-in stand-in. It runs the instrument with no simulator process and no plugin.
An instrument is a folder with info.xml, logic.lua, resources/, and optional lib/. A .siff is that folder zipped. A premium .sisx ships bytecode and encrypted resources, signed, with no logic.lua.
Not Java. Not a custom instrument editor. Hardware on ESP32 and Arduino Nano is next, and it is not in this version.
