This is the electronic keyboard that creates and records 16 separate tracks in the same manner as professional musicians. The track sequencer allows separate keyboard instruments to be recorded on-the-fly over previously recorded tracks to form a song, ideal for laying down a drum track, then layering with bass, guitar, synthesizer tracks-up to 16 instruments. It has 61 full-sized keys that span five octaves, including a nine-slider drawbar organ control panel for creating classic rock keyboard overlays. With 250 pre-set rhythms and 800 individual tones, it can replicate nearly any sound made by a real instrument, including piano, strings, brass, synthesizers, percussion, and more. Full, rich sound is provided by four built-in 7-watt speakers; with a stereo lineout/headphone jack. Songs are saved as WAV files onto an SDHC memory card (required); supports up to 32 GB cards. Plugs into AC or requires six D batteries. 5 3/16" H x 14 7/8" W x 37 1/4" L. (5 lbs.)
