KeyStep Pro Mods

New tricks for your KeyStep Pro. Pick the mods you want, drop in the official firmware file, and flash the result with MIDI Control Center like any update. Everything happens in this browser. The guide explains every mod, flashing, and going back.

At your own risk. These mods are unofficial changes to the KeyStep Pro firmware, not made, checked or supported by Arturia. You flash them entirely at your own risk and responsibility. They come as they are, without warranty of any kind, and the author is not liable for any damage, data loss or malfunction of your instrument. Flashing the official update puts the original firmware back.
