Tunio engineers built MIDI controller support into a browser-based radio studio

The team behind Tunio's Broadcast Studio wanted radio hosts to control mics, faders, and jingle pads using physical hardware without leaving the browser or installing extra software. They used the Web MIDI API, supported in Chrome and Edge, to let USB-MIDI controllers send signals directly into the studio interface. A custom MIDI Learn system was built so hosts could bind any hardware control simply by selecting a studio action and touching the physical control, with the software automatically detecting whether it was a button or fader. To handle the wide variety of controller layouts, the studio lets users configure the pad grid shape to mirror their hardware, ensuring physical and on-screen controls stay spatially aligned. The project aimed to bring the tactile feel of traditional broadcast hardware to a fully browser-based live radio workflow.
