Latest installer

Per-user install (no admin needed). SmartScreen will scream because the binary isn't code-signed — click More info → Run anyway.

After installing

1. Run XOSC from the Start menu.
2. Click + Input, then OSC Out on the toolbar.
3. Drag a wire from one to the other.
4. Click Bind next press on the input node, then press your physical button.
5. In Resolume: Preferences → OSC → OSC Input Port = 7000 (the default).
6. Press the bound button. Resolume reacts.

Stuck? Toggle the Debug panel inside XOSC — every captured event and every OSC packet is shown there with a Copy button. Paste the log into a GitHub issue.
