Keyboard with 25 short-length keys for greater portability. It has a USB and lightning connection for direct connection to a Mac/PC or iPhone/iPad, MIDI in/out ports (via an included MIDI 2.5mm TRS adapter), and an Audio out jack for connecting to headphones or speakers. It can also work autonomously, without being connected to a computer or smartphone, for example, to connect to MIDI equipment (synthesizers, sound modules, drums, etc.). Includes the SampleTank SE Mac/Win App.
