Arcana can be adjusted to accommodate those with different physical abilities. Even those who use their feet, mouth or other parts of the body.

The E-Box enriches the instrument further. By connecting to different switches and sensors using the E-Box, players with certain physical or learning difficulties can benefit from a playing experience that is suited specifically for their needs.

The E-Box has six inputs; 5 that can be used to replace the 5 keys, and another one which can replace the strum stick.

The E-box enables connectivity with standard switches and sensors that are in frequent use by people who have various disabilities. In addition, external switches, such as movement sensors, light sensors can also be used, so that anyone can play the Arcana Strum comfortably.
