The Amstrad CPC use the General Instrument AY-3-8912 sound chip, providing 3 channels, each configurable to generate square waves, white noise or both. A small array of hardware volume envelopes are available. The C64 use the SID sound chip with also 3 channels, each configurable to generate 4 different waves forms : sawtooth, triangle, pulse, noise. It offers other features, much more than the AY-3-8912.<br />
So is it possible to listen to SID music on an limited Amstrad CPC ? The answer is yes, and if you are lucky enough to read french [or use a translator], you will be able to read the article [http://quasar.cpcscene.comnet/doku.php?id=coding:sid "les SID-Voices"] on Quasar. So to resume, yes you can do it on a plain Amstrad CPC, but if you play 3 SID-Voices, you wont have enough CPU time to do something else. Otherwise on an Amstrad CPC+ using the DMA, you will be able to do something else than playing music. The Quasar article comes with the '''AY+''' source to play SID-Voices on a CPC+.<br />
