SAVIO_ASTRAL ASTRAL keyboard software

Remap keys, set the RGB, record macros and change device settings on the SAVIO_ASTRAL ASTRAL. Free and open source. Use it in a Chromium browser with nothing to install, or download the desktop app for Windows, macOS or Linux. Either way it runs entirely on your own machine: no account, and the browser version makes no network requests once the page has loaded.

What sharkfin does with the ASTRAL

  • Remap any key. Click a key on a picture of the board and give it another key, a mouse button, cursor movement, the scroll wheel, a macro or a media control. Base and Fn layers both. 4 onboard profiles.
  • Lighting. 18 backlight effects with direction options, full RGB colour, brightness and speed, changing live as you drag.
  • Per-key colour. Paint individual keys and send the pattern to the board's flash.
  • Macros. Record key and mouse sequences with per-event delays into the 50 onboard slots, then bind a key to one.
  • The knob. Turn left, turn right and press are all remappable. From the factory: volume down, mute, volume up.
  • Backup. Export everything to a file and restore it later.
  • Magnetic switches. This board has them. sharkfin does not configure actuation or rapid trigger: the firmware does not answer those commands. Everything else on this page still works.

sharkfin draws the ASTRAL key by key, so you remap on a picture of your own board.

Connecting

Plug the ASTRAL in with a USB cable. There is no configuration channel over 2.4 GHz or Bluetooth on this hardware, so a receiver or a Bluetooth pairing will not do. Settings are stored on the keyboard itself, so everything you change keeps working wirelessly once you unplug. sharkfin never flashes firmware, so there is nothing here that can brick the board. On Linux, both the browser and the app need a one-line udev rule before they can open the keyboard.
