 Starting in 1992, the ALESIS Corporation, a company which made digital drum machines and inexpensive analog audio mixers introduced the first multitrack, eight track, project studio, digital 8 track machine.It was named the ADAT, after the earlier 2 track digital recorders of the time known as DAT (Digital Audio Tape), which were based upon a small spinning head, similar to a consumer video recorder.The ADAT machine recorded its data in an already well-established consumer format based on VHS videotape recorder technology.
