The instrument
The PortaSound PSS-370 from 1987 is an entry-level portable music keyboard. The Portasound PS and PSS synthesiser series were produced in the 1980s and 1990s as mostly low-cost models. The first series, the PS-1, PS-2 and PS-3, was launched in 1980. The name Portasound refers to the portability of the instruments, which are battery-operated. Some were designed for children and are equipped with small buttons and simple preset functions. A card reading system was introduced in 1982, allowing players to learn and play along with sequenced songs. Some higher-end keyboards have advanced features such as programmable synthesiser controls, midi capability and sampler functions.
