Each button on the DX1 Input System let’s you use whatever label you went. Heck, since the tray itself is clear, you can even put whatever background you want. Just slide in your labels.
The keys are placed anywhere you want. Put a key in the wrong spot? Simply twist off and restick wherver.
Given there’s only 25 keys, this is meant as a supplement to your keyboard. Do not throw away your QWERTY.
