Case study

fretwire: reconstructing Line 6 HX USB control

fretwire reconstructs the Line 6 HX family’s USB control protocol for an independent Linux editor. Its Rust code covers device sessions, message encoding, preset parsing, and a graphical editor; protocol notes describe captured MI_00 frames and request-response behavior. Model and control data are imported from the user’s HX Edit or POD Go Edit installation.
