Description

Control web pages sliders, knobs and buttons using your MIDI controller. Get started in seconds thanks to our simple MIDI Learn workflow. Although you can always expand the mapping editor to fine-tune the behavior, control range and more settings, individually for each mapping you create, on any website. Key-Features: - Instant Target Selection (no need to dive into any code!) - DAW-style Simple MIDI Learn Mode - Advanced MIDI Settings per individual mapping - Multi-controller support - Mappings Template Import/Export support Privacy & Integrity matter to us: - We do not collect any user data or any analytics tracking inside the extension. - MIDI data is processed locally within the browser. - Mappings are stored locally on the user's machine (Export/Import of JSON files). - No data is sent to any external servers. Free Extension Compatible with Chrome and all Chromium based browser. Made with love for the community! Note that the elements you wish to control needs to be individually exposed in the code. Otherwise you may not be able to target them. Based on how websites are made, not everything might be controllable via MIDI, but it works great with online synths, volume, sliders, WebSDR and similar applications.
