knob.monster — Browser-Native WebMIDI SysEx Librarian & Patch Manager

[knob_monster]

Hey everyone,

I wanted to share a project I’ve been building to solve the clunkiness of managing vintage synth patches: knob.monster.

It is a lightweight, browser-native SysEx librarian using the WebMIDI API. The goal was to eliminate the friction of legacy desktop utility apps, driver setups, and port configurations. You just connect your synth via USB-to-MIDI, open the page, and back up or restore banks instantly.

• Zero Installation: Runs entirely in any WebMIDI-supported browser (Chrome, Edge, Opera).

• Current Support: Dedicated templates for Yamaha DX7 and Roland Juno-106, plus a generic SysEx dump mode.

• Workflow: Drag-and-drop .syx files to import, click to audition presets live on your hardware, and save banks to a clean cloud library.

• Sandbox Mode: Includes a simulated synth toggle so you can test the interface and bank structures even if you aren't near your hardware.

If you have a DX7 or Juno lying around, give the tool a spin. I'd love to hear your feedback on the workflow and what synths you want to see supported next.

Cheers,
The Half Radiation Team
