A AY-3-8930 sounds much richer in native mode than a AY-3-8910. Sadly, one one pc game has support for the pc SoundMaster card (which has the same chip). The game is called "Where in the world is carmen sandiego". We tried to dump the AY-8930 data from the game but didn't succeed yet. Maybe we got the wrong archive.

For demo sounds you have to wait a little. Currently we are programming the CLPD etc. Fun fact: we didn't know that there was a stereo PSG card for Amstrad. Wow! Would be nice indeed to get support for the pt3 files later.

We try to let it work in a slotexpander too. Price we don't know yet. Depends on final features. Remember this is just a prototype. We are not busy with calculation production costs at this moment. First need to get the thing working.
I'm not sure what Hit9918 is suggesting but this thing is not the same as in the video link.

There are cards that add a 2nd PSG for the ZX-Spectrum too. One of them is called Turbo Sound. I have many PT3 files here that support this and will gladly hand you them if they'll be of help.

One question: does this card feature it's own clock generator? It would then be an a very elegant fix for the PSG pitch for turbo mode of Panasonic MSX2+ machines and homebrew turbo kits.

By sd_snatcher

Prophet (3088)

13-02-2016, 12:36

BTW, since the card is still in prototype stage: why not a YM2203 (or even a YM2608) instead of the AY-3-8910? This way you would have two enhanced PSGs in one card, and both with good compatibility with the original 8910. And it would be of great help for Grauw's VGM player.

By Grauw

Ascended (8507)

13-02-2016, 12:55

sd_snatcher: It’s the Microchip Technologies AY8930 (EPSG), not the GI AY-3-8910.

Also Panasonic MSX2+ machines have a standard 3.58 MHz bus clock so there’s no need for a separate clock crystal. (Nonstandard 7 MHz buses are nonstandard so I don’t think they need to be supported, but that’s imo.)

The newspost should be adjusted by the way, “AY-3-8930” does not exist, should be “AY8930”. Also it may be worth more explicitly mentioning that it is a chip by MT with enhanced features, since several people seem to confuse it for the original (no real surprise with those similar product numbers).

By sd_snatcher

Prophet (3088)

13-02-2016, 13:14

You're right. I missed the info that both PSGs would be the AY8930. In the picture I saw from Nijmegen, I had the impression that it had one AY8930 and one Y-3-8910.

Can't follow you on this one. When I put my Panasonic 2+es on turbo mode, the PSG pitch goes up. Not the distorted type you get when putting a modded MSX2 to 7MHz, but it flies up. And since the turbo mode is not exactly twice as fast as the normal mode, the PSG will be very dissonant if mixed with PSG or SCC.

I do hope Darky has its own clock for the sake of both Panasonic 2+ machines and the 7MHz modded MSX2 machines. The latter not because it's not an MSX standard, but because it exists.

By flyguille

Prophet (3029)

13-02-2016, 16:15

yes, one of the big reasons why somebody will buy this is for avoid using the internal PSG which pitch up on 7mhz turbo mod.

But if it don't has its own crystal osc., that is a thumb down.

Only the Panasonic 2+’s internal PSG is affected by the higher clock frequency, because it’s built-in to the MSX-Engine which has to run at CPU clock speed. However, the bus speed remains 3.58 MHz so any sound cartridge you plug in will have the correct pitch and do not need their own crystal.

I'm a little bit confused.
In MSX sound scene we have:
PSG
SCC
OPL with 32K of sample but 256K expanded is better
OPLL
OPL4 with sample ram
COVOX or TURBOR for PCM

Now we have a double PSG solution.

I think that sound on MSX is too crowded, also if OPL4 could work as an OPLL and OPL.
For Video is different: the v9958 "include" the v9938 features whic "includes" the TMS features. This is perfect and, for the next-gen MSX it would be better to think about a retrocompatible V9978 for the same reason instead of tje v9998 thet is not retrocompatible.
For MSX sound the solution would be a chip (and a cart) that can works as all the chiptunes in the list.
If we think that
- all MSX has a PSG
- MEGAFLASHROM includes SCC+ and another PSG (that would be nice to use for ePSG stereo)

we really miss a definitive CART FOR PCM, OPL, OPLL, OPL4, with sample ram.

What do you think about?

By Grauw

Ascended (8507)

13-02-2016, 19:27

I love having all kinds of different sound chips available for MSX. It’s something that makes MSX unique compared to other retro systems. The more the merrier! There is no such thing as “too crowded”.

If you care just about playing games just buy an FM-PAC and you should be set for 99% of the games.

AY pin says 0 volts or volume register value, that tells the state.

The best way to get an useful programmable interrupt in to apply a programmable divider to the vdp hblank clock (15KHz).
It should be independent by the 60/50Hz settings and by the turbo settings.

14-02-2016, 21:52

the best interrupt rate is counter/comparator values the same way as an AY frequency register.
and an interrupt per AY channel.
that makes the top AY synthesizer.

and on the R800 it makes digi samples.
the atari ST folks talk about mixing, but no mixing and no aliasing with this one. and the cpu just does a straight copy of the sample.

AY frequency register has 12 bits, minimum 27hz or so.
add 2 bits on the top for more vibration and 2 bits on the bottom,
i.e. simply a 16bit counter running 4x the AY counter,
which is a divider of 3.57Mhz anyways.

@sd_snatcher are you sure about twin PSG configurations on ZX-Spectrum? I thought it was on ZX-81. IIRC, all sound expansions for ZX-Spectrum works on the same port as internal Spectum 128 internal PSG works.

Apart from the 8910-8930 misreading, we already have a dual-PSG solution for MSX: Some cartridges has an AY-3-8910 embedded on FPGA code together with SCC code. This "external PSG" works on an alternate port, so with very little effort we can write code for two PSGs without the need to develop another cartridge. So, if we found it to be a good thing, maybe people start writting music for two PSG's on MSX. And Maybe @Grauw could support it on VGMPlay, as some arcade machines has twin-PSG music.

Trilotracker is limited to 8 channels. But darky + opll (or any other chip combi) could be possible with a redesign and a lot of work. I really am tempted to go this way other then making different versions of the tracker but lack a lot of time at the moment.

But there will be for sure a DarkyTracker version of Trilotracker

Darky doesn’t have the AY-3-8910. It has the Microchip Technology AY8930, which has a bunch more features like pulse width and per-channel envelopes. It’s a pretty interesting sound chip. So you are already getting an upgraded PSG (but not the OPN).

It's also possible to address those two new chips independent of the msx psg, so in fact you will have three psg's at your disposal.

Not sure if I am still fully up to date but I have this on my feature list I collected:
- By default the first PSG AND the second PSG are on the same registers, with detuned clock, as the internal MSX PSG.
- But all PSGs can also be initialized to their own ports.
- IIRC the effects and volume can be set for the 2 extra PSG's while they are mirroring the internal PSG.

For now the default is that the two new psg are mirroring the msx psg but in the near future it will be possible to save a config of your own likings.
