Hi,

@Dreamblaster just sent me a prototype for testing.
So I now have PicoVox and will be putting it through intensive testing on my 386SX laptop

I also had an idea for a logo that could make for a nice little wordplay.

i think it suits your project nicely and also has a high memorable factor.

Thanks, will report soon.

Glad to hear that older architecture than 486 SX will be tested. Please, in case you find any bugs, report them so that we can try to patch them.

Regarding the logo, we have already come up with something a bit more simple, honoring both sound and the main component of the original covox – resistor.

Hi,

Just to share I received a PicoVOX Serdaco edition with 3xPicoRhino 😀

This picovox should be a very useful add-on for my A2286 (286/8) PC-Setup equipped with an additional LPT-Port and also a very useful add-on for my PS/2 E Machine.
When and where can I buy one? Thx!

Oh wow, it's so cool to see it available for pre-order on Serdashop already! 🤩 Good job @jansakos and everybody else who made it happen.

@dreamblaster I see two prices next to each other. Is the cheaper one (€45) the introductory price? If so, how long will it be available at that price?

Also, I assume that complementary picovoxes will be sent out to prominent retro YouTubers at some point? Or should we allow the firmware and software utilities to mature a bit more first?

I've been thinking about trying my hand at writing a multi-game Covox/DSS driver patching tool. Apparently, all games that use Miles AIL 2.x or DIGPAK drivers can be patched to support these parallel port devices. It would be nice to expand the support for parallel port sound devices to a larger number of games, so there will be more interesting stuff to showcase by those YouTubers.

A version or fork of SBEMU or VSBHDA that supports the picovox as an output device would also be cool.

There's a price without VAT and with VAT. (depends on where you live)

It already works quite well.
Would be happy to send to youtubers indeed - feel free to suggest who

that's great !

it works fine on my 386SX Laptop,

i had one small glitch which was caused by the cable i used.
But after plugin it directly into the Port it works almost perfect.

- iplay has some small pops sometimes while playback, even if i go further done in < 16khz.
- MFED Playback in Stereo on 1 Mode is perfect, don't have any Problems at all.
- MEGAPLAY has Issues, like missing voices - i send ZIP to dreamblaster so you can verify (F2 changes output devices)

But there at least 2 methods of Stereo on 1 Playback, maybe Megaplay uses a different approach.

Other Stuff seems to work just fine, DSS, Tandy, CMS etc.
Tandy is hard to distinguish from the Original SN76489 Sound.

Some that immediately come to mind:

• LGR
• The 8-bit Guy
• Adrian's Digital Basement
• Retro Erik
• VWestlife
• Action Retro
• Tech Tangents

I'm sure others here can suggest more. Some of these vloggers have already published dedicated episodes about parallel port sound devices that the picovox can emulate, so they might be interested in making a follow-up video about the picovox.

Still, with more patched games available, as I'd like to work on, it might make for more interesting content, with additional games supporting parallel port audio.

Happy to hear that most modes are working correctly.

I feel like I will need to rewite The Disney Sound Source emulation to work on both cores, since now the timing is a bit off. It should not be that hard. I hope that it will make the sound coming from the picovox (especially in Dungeon Master) a bit better.

Regarding Stereo-on-1 emulation, I have heard multiple times that there are more versions of it. However, I still have to find the second one. If there is anyone who knows any other version of Stereo-on-1, please, let me know. After some digging I was able to find newer version of MegaPlay (version 1.08) which includes the same documents written by Mark J. Cox, therefore this Stereo-on-1 technique should be the same as in the ModPlay Pro. Maybe there is some difference between how they use the sound device itself, I will try to adjust the emulation a bit since I feel like I implemented something wrong (thankfully everything is software-based, therefore small firmware update should do the trick).

Also, I have changed OPL emulation library so that it is a bit closer to the original chip. Also, it supports YMF262, meaning I should hopefully be able to add support for OPL3LPT in near future and before the public release.

Maybe this Helps.

i'm trying your changes later!

Does the OPL/Adlib mode support 'banging' mode operation?

There are a few games that do 'voice' over adlib through tone manipulation that's essentially just 'banging' the chip with commands in such a way that pulsed soundwaves get generated.

Wizardry 7 is such a title. (It also 'bangs' the soundblaster DSP in a similar way to do voice output)

Almost no existing adlib/opl software implementation does this in a way that hardware opl does, and I was just curious.
