A flexible and powerful MIDI controller anywhere you have a browser!

MIDI Surf is a browser-based MIDI controller that is optimised to work on a range of devices, including tablets and smartphones. It is highly customisable, enabling you to make a controller that is exactly what you need to make or perform your music at any given moment.

Take a look at this video to see it in action.

Here's a quick rundown of some of the features:

• Install to your device as a progressive web app and use offline!
• Buttons for playing notes, chords and sending CC
• Faders for smoothly changing CC
• Set MIDI parameters automatically by pressing the key or changing the parameter on your device!
• Custom isomorphic keyboards with any size and offset you like
• Create scale keyboards or chord banks in seconds
• Store pages and modules to reuse later
• Share presets as a link
• A MIDI event viewer so you can see exactly what MIDI messages your device is sending

As useful as it is just now, this is just the beginning for MIDI Surf, I have lots of features in the pipeline. Check out my YouTube channel for development videos, tutorials and other music technology/programming related content!

Please consider supporting the development of this app if you enjoy using it, I'd really appreciate it if you did! You can join our community on Patreon and help guide the direction the app (and future software from Mo Chreach!) takes, or buy me a coffee/beer/cup of tea/sausage roll on Ko-Fi.

On both desktop and mobile, I'd recommend using an up-to-date version of a Chromium-based browser to use MIDI Surf, such as Chrome, Edge, Vivaldi, Brave etc. Currently (as of Jan 2023), Safari and Safari on iOS do not support the Web Midi API. Take a look on Can I use for an current browser compatibility.
