Hola,
a new fancy nice sounding musik disk was made and released today. Full of old musik using only the envelope generator of the AY chip to create 6 channels of raspy sounds. Some wifes and gfs will probably like it. Have fun and merry xmas!

The AY really need a compendium ;-) ... BSC dit it !!!
Congratulations for this nice music using the AY at its maximum capabilities !
Christmas time is here with nice gifts from BSC !!! :D
Great news! Do you have an archive with the files? DSK is not really handy when you just have albireo, x-mass or ...
I tested it on a real CPC. This is interesting. 6 channels you say? I admit I cannot hear more than 3. Since the sounds are very "raspy" and are all the same, they conflict and prevent from hearing them individually.
I guess this is some kind of PWM?

How would you transfer the files from the archive, assuming it is something like a .zip file? I typically use https://github.com/cpcsdk/idsk to move files in and out of DSK images, is that not an option for you?

I think it's more related to the 1-bit engines (https://gwern.net/doc/cs/hardware/2020-troise.pdf) used on the ZX Spectrum. The tone generators re-trigger a single ramp-down from the envelope generator every time one of the virtual channels period has a zero-crossing. And there are 6 of those, coupled such that 3 pairs play the same notes slightly offset to introduce subtle beating/interference. The engine could just as well play 6 independent melodies, but I have chosen to pair them together because I like how the beating adds richness to the sounds. Yes, it's raspy as advertised :)
