The Roland Music Style Card was a ROM card containing programmed music rhythms to extend those available in the E-series ‘intelligent synthesisers’ made by Roland.
The first of the ‘intelligent synthesisers’ was the E-20, released by Roland in 1988 as the first product of Roland’s new European arm, and was aimed at the high-end home market. A number of variations of the first-generation E-series were released, such as the cut-down E-5, and the enhanced E-30 and Pro-E (an ‘intelligent arranger’).
For the first generation of the E-series, the cards were prefixed with TN-SC1 and there were 14 Music Style Cards in the first series released between 1989 and 1991.
There was a subsequent series of Music Style Cards with a slightly different shape and prefixed TN-SC2 for later E-series synthesisers such as the E-35, E-56 and E-70.
