“The Commodore 64 with its famous SID-chip really blew everyone away when it was introduced back in 1982.
It could play 3 different sounds at once, but during the years musicians and programmers learned to drop sounds in and out during the course of the music so it gave the impression that there was more than 3 different sounds playing at the same time.
The two different original SID chips, the 6581 and the 8580 has some differencies in sound and capabilities, and there’s always discussions going on about which sounds the best. I’m no SID purist, I’m a musician first and I’ve grown to appreciate the 8580 as the main SID source when I use the C64 in my music.” – Espen Kraft
