The C.24 is a wireless piano keyboard designed for iPad. The ultra portable C.24 transforms from a cover into a piano-style keyboard at the touch of a latch.


The use of anti-polarity magnets creates the semi-weighted feel of the keyboard. By using magnets instead of traditional springs reliability and longevity are extended.

Each key press is sensed by an infrared emitter detector pair providing real time analog position data. Optical key tracking technology delivers MIDI velocity, monophonic aftertouch as well as detailed performance capabilities. The use of “lightwell architecture” virtually eliminates interference from ambient light (including sunlight, strobes, etc.).

Wireless Communication

The C.24 communicates with the iPad via Bluetooth Low Energy. This wireless technology eliminates any need for a physical connection.



Miselu’s KEY application makes it possible to use Bluetooth devices to make music. KEY allows you to assign your keyboard’s output to any CoreMIDI compatible iOS application. You can also save presets, allowing you to quickly change your setup during a performance.

The app will also facilitate “grouping” of multiple 2 octave C.24 keyboards into a single 4 or 6 octave instrument (supported by magnetic latching of adjacent C.24’s).

HEM Capability

Miselu designed an open standard for hardware expansion modules. Tactile controls such as knobs, faders and XY pads will be available in the future. This allows you to configure your C.24 based on your performance requirements.
