MOS Technology SID.

"SID" refers to a SIDfile, *.SID, too. Now playable -with some less quality- on CPC with Geco's Player. [http://www.hvsc.c64.org/ SID Resource site.]

==Features==

* external audio input (for sound mixing with external signal sources)

* random number/modulation generator

==Technical details==

Despite its documented shortcomings, many SID musicians prefer the flawed 6581 chip over the corrected 8580 chip. The main reason for this is that the filter produces strong distortion that is sometimes used to produce simulation of instruments such as a distorted electric guitar. Also, the highpass component of the filter was mixed in 3 dB attenuated compared to the other outputs, making the sound more bassy. In addition to nonlinearities in filter, the D/A circuitry used in the waveform generators produces yet more additional distortion that made its sound richer in character.

==What about the amstrad ?==

Such "Sid emulation" came lately in Amstrad world, even after the commercial era.
