Temat: Nowy soundchip AY8930 dla ST ?
Ciekawostka zaciągnięta z forum na stronie DHS:
"Someone actualy managed to put an AY8930 soundchip in a ST and apparently make use its additional features (compared to the classic YM2149/AY8910):
You might wonder: "What´s this all about with the AY3-8930?" (See previous postings)
Here´s a short list of what the expanded mode has to offer (and it´s quite a bit, or two ;-)
-------------------------------------------------------------------------------------------------------
* Independent envelope periods for all three channels (so you can set different envelope timers for each channel instead of one for all)
* 16bit frequency resolution for all channels (instead of 12bit)
* 8 bit divider for noise clock (instead of 5 bit). This gives much better drum sounds and deeper rumbling noise than the high pitched hisses we´ve been limited to
* AND + OR Masks for noise polybit output (this will give Pokey-like effects, kinda "distortion" in the range of pure sounds to complete noise)
* Duty cycle control for all channels independently (vs. fixed 50% previously). This makes flanger and filter effects possible
Can´t wait to hear some of the above extra-effects!
