Yuhojin EK-107 portable kids keyboard with some cool built in features, but is also a great device to circuit bend. All printing is in Japanese, so I don't have specific names of sounds or functions, but keyboard is fairly intuitive in its similarity to other kids models. Please watch attached video for demo of features. Basic specs include two channels with a number of different tones, two channels with various songs/rhythms with a button to isolate drums or melody, one channel of a variety of effects to put on tones like delay or chorus, 10 sound buttons with samples like drums and DJ screams, record function, volume and tempo control, and unfortunately no output/input jacks. Powered with 3 AA batteries, made in China.
