STRUCTURED/ADAPTIVE SYNTHESIS Before 1986 attempts to reproduce the sound of the piano in digital instruments were based on sample based synthesis. This was done by Kurzweil in 1984 with its K250. It was expensive and not as sophisticated as today's digital piano sounds. Just two years after Roland introduced its Structured/Adaptive Synthesis. SAS divided the keyboard into more than 30 zones where pitch, brightness, individual formant structures and string enharmonicities vary. It was unlike the pre-existing sample-replay systems. Roland engineers sampled and analyzed instruments' timbre with various pitches and velocities. They designed an algorithm that reproduced the necessary harmonics. It made possible to reproduce the sound of a grand piano better than with the other techniques available then. The polyphony was 16, which was considered acceptable at the time. Roland discontinued the original SAS in 1990 when Advanced SA was introduced. In 1996 a 64-voice stereo implementation was developed. ROLAND'S NAME It may seem strange for a Japanese company to have a Western name, but Roland was founded with export in mind. Ikutaro Kakehashi heard that the name of his previous company, Ace Electronic Industries Inc. , was often mangled in pronunciation, sometimes unpleasantly; so he looked for a good-sounding name which would be pronounced roughly the same in all of his major export markets. He found the name Roland in a telephone directory. Ironically, the name is difficult to pronounce correctly in Kakehashi's native Japanese , which Does Not Distinguish The 'L' And 'R' Sounds As In English . Roland was ''not'', as is often claimed, named after the French epic poem '' La Chanson De Roland ''. TIMELINE OF NOTEWORTHY PRODUCTS
