I'm using the Opl2LPT2 v2 on a lenovo m32 thin client .running free dos . I was wondering if anyone had any sugrestions to reduce the level of buzzing I'm currently encountering with it. I've tested it with an exsternal power source, and using usb power from the m32 . In both cases the volume is very low, and their is a high level of 'noise' . Initialy i thought it was a grounding loop or some crappy speakers but i've tested multiple speakers and tried swaping to an exsternal power source. Any sugestions would be much appreciated.

Well as much as i would rather this post fade into nothing ness, I wanted to say thanks to everyone who offered help in this space. After trying with standard head phones per Dreamblasters sugestion....i realized i just wasn't plugging in the speaker jack well enough.. soooo dumb.

Thanks y'all for your help . and for such a cool little device.

Here’s a thought: Would it be possible to change the lpt port address to 0388 by editing the bios? My Schneider EuroPC’s bios setup shows the address of the lpt1 but it’s not changeable. Since the only ISA slot i have is already occupied by the XT-IDE, I figured I might as well modify and make a custom bios that sets the address of the lpt port to 0388, assuming it’s doable that way. That way, I wouldn’t need to try to patch every game I might want to play.

No.
But instead games can be patched to use 3bc instead of 378h

This is my new little midi to YM3812 vgm conversion tool I'm currently working on. Unfortunately, it still fails on many files during the midi parsing or note alignment, but at least, it can produce a fine result on some. I will have to add more options in the future. I designed it for my theoretical Atari 2600 add-on in the future that will have a YM3812 on board.

The program is specially designed around the YM3812, it fetches the midi notes on the 9 OPL2 channels so it will play as many notes of the channels as it can while counting where it would require the leat bytes to write for the instrument changes.

The project was made in Intel Fortran.

Project available here: https://github.com/MemberA2600/MID2OPL2
Combined with my player, you can enjoy your midi files on your modern PC pretending it's still the early 90's.

Sigh... If only all game developers had the discipline and foresight to properly look up the I/O port addresses of the available LPT ports in the BIOS Data Area, instead of just lazily hard-coding the I/O addresses that the original IBM PC happened to use... That's the way it was supposed to be done, even back then. It wouldn't have affected performance in the slightest, and it would've been easy to do. 🙄

It would be nice if parallel port I/O address patches would add a BDA lookup routine. Although I understand that would make the patches much more complex, since just replacing a few bytes in-place wouldn't be enough at that point.

I never have imagined that the rules of midi were made to be kicked up. 😁 So now I have to make sure all the files on my computer converts without any exception and will give a tolerable result, after that I will have to do a lot of finetuning.

Good morning,

I am the owner OPL2LPT product and I have a problem.

After connecting to the LPT port and entering the command A:\>adlipt

I have the following message below:

A:\>adlipt
ADLiPT 0.85 github.com/pdewacht/adlipt

Error: No supported memory manager found

Requires EMM386 4.46+, QEMM 7.03+ or JEMM

I can't deal with this problem.

I am asking for tips and help in solving the problem

Tested on Contura 4/25, 3/20, AST Bravo NB 4/25 S laptop

The card is working because it works normally on an IBM 355 laptop.

Marcin from Poland

You need to be in DOS with a memory manager loaded not just a DOS command line window opened from Windows.

Contura problem

I get the sense that english is not your first language, with permission of the mods, I'd ask that you allow them to post in their primary language, and we might be better able to communicate with them.

I don’t see how that would help, it would just move Google translate from one end of the conversation to the other.

The impossible often has a kind of integrity which the merely improbable lacks.

Unfortunately, most native English speakers don’t speak additional languages. I learnt French in high school, but never had a chance to use it in real life, so 30 years later, all I can recall is “I’m thirsty”. In my defence, I do live in Australia which is a very long way from everywhere.

While that may be true to some extent, a lot of non native English speakers are present here and do speak other languages to a varying degrees. For example, I would like to believe that while English is not my mother tongue, I do speak it (read and write as well) on a level that most people in my personal and professional entourage would consider on par with that of a native speaker, albeit not one with a degree in literature . I am also fluent in French (post high school native level) and I do understand Polish and Spanish (both to a lesser degree).

Quite a few people here are in a similar situation. While automated translations have improved by leaps and bounds over the last few years, they are still not perfect. Taking this into account, I believe that continuing to enforce English as the standard language here makes sense, but possibly allowing posters who use translation tools to also post in their native language (in addition to the auto translated to English version) might be something worth considering . Anybody responding to such a post would be required to post in intelligible English while also being allowed to include a response in the poster's native language. Of course, this is not my decision to make .

English just happens to be time most spoken language globally, and by a massive margin. So it does make sense to use it as the standard here. I’ve helped folk using other languages to ask questions on GitHub many times, and it’s quite painful relying on Google translate.

The thing that really causes the most issues, is not being able to easily read through the thread, as every second or third post is in a different language - this is the reason most forums enforce a single language.

Eg https://github.com/grblHAL/ESP32/issues/17

IMO, I think this is an eminently reasonable approach. No reason not to shoot for an inclusive community.

It’s got nothing to do with being inclusive, it’s about being able to follow topics, e.g. try reading the last half of this GitHub issue, it’s a real struggle, even for me and I was the one helping out.

If you go to a German or Spanish forum, they get rightly annoyed if you try to post in English, as it ruins the flow and readability of the discussions.
