Case study

Unrack: extending reconstructed t.racks DSP control

Unrack controls the t.racks DSP 4x4 Mini Pro through WebHID, an Android USB bridge, or an ESP32-S3 Wi-Fi bridge. It builds on earlier protocol research and provides rebuilt transport, state management, and interface code; its protocol notes detail request and reply frames carried in 64-byte USB HID reports, commands, and parameter scaling.
