I read about this at dhs.nu:
As I´ve got hold of some AY8930 PSG chips, I´ve resumed my old project to upgrade sound capability of the ST (while staying backwards compatible).
All info about the project can be found at YMROCKERZ´ site, have a look at the recent entries on the board there.
All chip musicians: To get the action started, I´m offering to modify your STs with the new chip for a small fee (the first samples of the chips cost EUR
28,- per part). The work will be done for free!
I hope to see feedback especially from programmers who adapt existing trackers/players to the new capabilities (and I think it will be worth the effort!).
Now it´s your turn – contact me…
And some more info from the YM Rockerz board:
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!
Interesting.
