PORTATONE PSR-7000

With a large display and full-blown style sequence functions, the portable 61-key Portatone PSR-7000 featured many of the elements on an arranger keyboard.
Although originally intended to be a Portatone instrument for home use, the ease of arranging rhythm and bass accompaniment made the PSR-7000 popular among professional musicians who play and sing at nightclubs and other venues.
