The Electro-Harmonix Effects Interface Hardware Plugin is a clever bridge between pedals, plugins, and your DAW, designed to make hybrid setups feel natural and immediate. It lets you route audio seamlessly between physical guitar gear and software effects over a single USB-C connection, without the need for reamp boxes, DI units, or special converters.
In Hardware Plugin Mode, you can treat your pedals like DAW plugins, sending tracks out to real hardware and back again with hands-on control. Pedalboard Mode flips the idea around, allowing software plugins to live inside your real-world signal chain, effectively turning them into stompboxes you can run into an amp. It also works as a straightforward USB audio interface, making it equally useful in the studio or on stage.
By removing the friction between hardware and software, the Effects Interface turns pedals into outboard gear and plugins into physical effects, all in one compact, pedal-friendly unit.
