-[[MSX]], [[ZX Spectrum]], [[Atari]], [[Oric]]... all used chips from this family (sometimes it was the YM variant instead of AY...). The YM variant differed only in the hardware envelopes where it used 32 steps compared to 16 steps for the AY.

 As a result it is still quite popular in the actual Chip Tune movement as a vintage sound processor.

 ==Amstrad Plus specificity==
-The Amstrad Plus range include DMA sound channels. Each HSYNC, 1 instruction per active DMA channel is read. Each channel executes an instruction which allowed looping and sending data to AY registers. Each DMA channel is effectively a AY register playlist and once started is executed without CPU intervention. It was meant to reduce the strain on the CPU.
