The SHS500 Sonogenic Keytar is a fun and exciting way to play music. Its 37 keys play a like a full-sized keyboard and thanks to modern wireless technology including Bluetooth MIDI and iOS connectivity, the SonogenicKeytar can go anywhere on stage. Not a pro player? That doesn't mean you can't have a good time and thanks to JAM mode you can focus on playing the rhythms while the instrument worries about playing the right notes of songs. Play through the Sonogenic's built-in speakers or connect to an external PA through its professional-grade 1/4" AUX Line output jacks.
