A piano is generally not something you tuck under an arm and bring along for the afternoon. This 49-key version takes the show (or practice) on the road, replacing the usual rigid casework with a flexible silicone keyboard that rolls up when the music is done.

Unrolled, it provides standard piano-style keys along with multiple tones and demo songs, plus echo, sustain, and record/playback functions for a little experimentation. A built-in speaker handles everyday playing, while the headphone and external-speaker connection offers quieter practice or a little more volume when called for.

When it’s time to move on, the keyboard rolls into a compact bundle for easier storage and travel. Powered by USB or four AAA batteries, it’s equally at home on a desk, kitchen table, or wherever else a flat surface can briefly become a piano.
