I'm exploring the possibility of using a programmable keybord like this one:

to expand and simplify my keyboard shortcuts.

Now I'm wondering if there is the possibility to use a musical MIDI keyboard instead? E.g. like this one:

This solution would be much cheaper and, in my opinion, "smarter".

Anyone have news of such a project?

  • You would need to check what keycodes your OS receives when you press keys on the MIDI keyboard. If you're on Linux, you can use xev to do so. – Dan Feb 20 at 20:15

    there is a package on ELPA, elpa.gnu.org/packages/midi-kbd.html This allows you to use a MIDI device for input to Emacs. It turns key presses on the MIDI device into key-events which you must bind to commands. I have not used this so do not know what it really does for you. By the way, once you have set up your MIDI keyboard using midi-kbd you can check the key-events it has assigned to key presses on the MIDI keyboard by typing "C-h k" and then pressing the key you are interested in on the MIDI keyboard. – Aidan Schofield Feb 20 at 20:50

    [maybe OT] some tried to connect multiple keyboards and change the keymap of one of the them superuser.com/a/787910/203364 – Matteo Gamboz Feb 21 at 7:50
  • Kind of OT, but I guess it's a consequence of the question. OTOH, it would be good to make your answer a bit more complete, e.g. pointing to setxkbdmap and -device to make the answer useful even without folling the link. – Stefan Feb 21 at 13:37

I'd suggest not using a midi keyboard, but instead, using any keyboard which is capable of running QMK firmware.

This has the following advantages:

  • It can work in any application and doesn't rely on configuring your operating system/software for non-standard input devices (from the perspective of using it for keyboard shortcuts at least).
  • You can enable modifier keys to switch layers.
  • You can configure keys to run multiple keystrokes (including typing in text).
  • It can record/playback macros.

You could use the plank keyboard or lets-split as a large num-pad, programming F-Keys 13..24, as well as other available keys.

For example, you could bind each key to a Hyper-[A-Z] combination, assuming you're not already using the Hyper modifier elsewhere.

See qmk/keyboards for a full list of supported keyboards.

  • Interesting but not cheap at all. ;-) – Gabriele Nicolardi Feb 21 at 23:37
  • QMK supports loads of keyboards: falba.tech have cheaper options (stand alone numpad's and lets-split may be viable alternatives). – ideasman42 Feb 21 at 23:57
