Building a desktop bridge for hardware control with Codex's computer use on REAPER

CtrlAltDwayne · x · 2026-10-25

@CtrlAltDwayne says Codex's computer-use capability is why he still heavily uses it: he's building a desktop bridge for an app that controls a hardware device, targeting an in-demand market people will pay for. The screenshot shows Codex driving the REAPER DAW — reading plugin preset data, toggling Master Bypass and verifying values — while planning full-block editing tests with a disposable project and generated test signals to check readbacks and audio continuity, explicitly keeping payments out until workflows are proven. A real-world case of using an agent's computer use to do hands-on GUI engineering.
