FINALLY, IT EXISTS!!!
THANK YOU!!!

EDIT: Noticed there's a strange pitch bend issue when playing fastway.mid (Rise of the Triad) around 1:37, the same bug i've heard in PCem in Win3.1's FM midi driver even...

Ooh, I like virtual sound cards 😁

This bug also exists in Windows 95/98. Original FMSynth sample driver haven't this bug. So i added this bug.

Ah.

It proved that my CMI-8738 card didn't have any FM synth part.
Never buy CMI-8738 as mine. I should find another one.

Driver used that you posted before
Re: I've got the OPL3 synth from a CMI8738 working in Windows 7 x64

Which error code ?
The code 10 means that OPL3 not found at 0x388 port.
Which CMI8738 chip's revision?
It seems to me that OPL3 exists if number of chip's revision 37 or less.
Which your PC's processor?
It seems to me that AMD processors don't allow to write on some ports.

Never mind. Your driver really tries to access my card's port 388 and my card only generates noise.
(Edit)
Confirmed FM won't work even in windows 98SE. every dos application's setup find fm but no sound.
In pure PC-DOS 7.00, fought with c3dmix.com, perfect SB16 Digital and detected FM but no sound.
CANNOT HEAR ANY FM SOUND WITH MY DARN CMI.

When writing an emulator, it's ok to fix bugs in the original hardware. 🤣

How do you configure the usermode thing? I can't find the "UI driven application" mentioned in the readme...

EDIT: also hitting stop does not cause the driver to stop, I have to kill whatever process accessed it.

Let me know which CMI are you using.

LP chasis type? Trapezoid one with least parts? or Full sized one with digital output?

They looks much better than ebay. Audiotrak refused to answer about FM support. 😠

My soundcard:c media 8738 sx 4ch.
Also fm don't work on some pc. Try on another computer.

Try this driver:

This driver for cmi8738 with integrated opl3 driver.Opl3 is working on CMI8738 IO Port + 0x50 port.

overwrite and DSEOed it in \system32\drivers. How can I check OPL3 works?

(I confirmed my card won't make any FM sound even in mixer in DOS, But SBPRO works.
In PEEKPOKE, PEEK C01A reports C8, POKE it 00 and 08 but 388 reports only FF.
The Adlib and compatible (fmsynth.inf driver) NEVER removed its yellow question marks itself as erroecode 10 in DM.)

Sweet midi player

Forget everything and decided to use user mode drivers. Old games as windows 9x's times supporting MIDI BGM works well.
I didn't tried but is it work with my ymf-724 in 32bit XP or later?

Hi, I haven't posted here in a while but bumped across this post while looking for something semi-related to Adlib and MIDI.

Wow! Really awesome, thanks very much for sharing this to the web, khokh2001! I've always wondered when someone would eventually pull this off.
Currently testing this in Windows XP x64, 7 x64 and Win 8 x64, working great with the user-mode drivers. I do have a YMF724F-V PCI card which only works under XP, so I might give it a go with the kernel drivers.

Also big thanks for sharing the source code too. I'm actually looking into seeing if it's possible to switch the default patches with say, patches used from .ROL music.

EDIT: OK so I have attempted to install the kernel driver on XP where I already have the YMF724F-V legacy mode enabled with PowerYMF. Regardless of methods of installation (Add new hardware, update driver on Legacy Sound System which has port 388h used), I get the following:

An error occurred during the installation of the device.

The class installer has denied the request to install or upgrade the device.

Assistance is required. Thanks.

Any status on fixing the bugs in usermode driver so that stopping playback in Winamp actually tells it to shut down? It is rather annoying having to shut down whatever program accessed the driver before I stop hearing stuck notes.

How are you getting stuck notes? I'm using Winamp and I have no problem other than that I would occassionally need to reset the MIDI driver via a MIDI, or restarting Winamp to address pitch bends left over from the previous song (this is common with many MIDI drivers).

I just use Media Player Classic.
