The new version of this tiny synth has a built-in speaker and a headphone jack, making it so you can connect it to recording systems or a PA. It's iconic metallic keyboard/sound strip can be used with the included stylus, and a second one can be played with your fingertip. There are various dials and buttons that can shape the sound, including controls for LFO square and triangle waves, a low pass filter cutoff, sub octaves, envelope attack and delay, delay time and feedback and an X button pulse with modulation.
This is the second revival of the Stylophone; when the manufacturer Dubreq reopened in 2003, it released the Stylophone X2 and the Stylophone Beatbox. This new Gen X-1 is a bit smaller than those versions, with a new layout for a more compact form. If you're interested in what little box can do, check out the video below.
