Re: Munt Reloaded - Development

1) There might be a problem in Ultima Underworld II's UWR12.XMI --- there's a low string note at the start that plays for a really long time. At about 00:30 or so into the song, the low note turns into a high-pitched squeak instead; once a new note on that channel is finally played, everything goes …

Great work. I never thought I would see the day that I would seriously consider putting my old LA modules away, but now I'm holding my breath :) I'm also working on some documentation of how the MT-32 works internally and how accurately we model each part. This should prove very interesting indeed. …

The driver can be made to work on x64, but not by the INF install. I wrote an NSIS script that will install the driver on x64 as well as Win32. KingGuppy has the NSIS script, but it is up to him as to what to do with it. I don't know if he has had a chance to look at it yet or not. Thanks again for …

Would anything be gained by using the Reverb ROM at this point? The emulator uses the other ROMs inside these machines already. Maybe! So far nobody has deciphered how it works (the reverb chip is a custom gate array) - there are only theories as to what the data in the ROM actually represents. …

- reverb mode 3 must be accurate but isn't thoroughly tested for now It requires some tweaking. Try checking some games that heavily use mode 3 reverb, for example in The Humans level 1 music, echo is hardly audible compared to previous version (and LAPC recordings from http://cosmic-dreams.net). …

Just to be clear, do you mean only the mt32emu.dll MIDI driver will be abandoned soon? Will the mt32emu.exe still be supported? I'm not even 100% sure what this is - SergM's Win32 app? - it's never been officially supported. There will be a new application that will run the emulator with an …

I noticed from your commits that you use digital samples for tuning the emulation code. Can you give a rough estimate on how much more tuning is needed to achieve 100% accuracy? As SergM said, almost everything except reverb is now close to 100% accurate, to the extent that you can compare real and …

Is the dosbox mt32 patch on par with the recent munt updates (like the wing commander correct sounds) or is it based on an older version? sergm's patch does not include any recent munt updates but it relies on the external libmunt. With the help of dynamic linking, DOSBox may require something like …

Well, there have been so many new versions of the emulator these days that I feel somewhat lost... I just wanted to point out that all these builds are based on the Munt git repository, which is changing rapidly right now. If you don't want to experiment with different versions (though it doesn't …

We're changing things rapidly enough that "the last update" isn't quite specific enough 😀 Git commit IDs would be useful. I'm working on the PCM log->lin conversion, and my most recent change makes PCM samples sound pretty awful (aside from one, which sounds divine 😀 ), so that may be the problem.

Regarding reverb: DelayReverb is experimental code intended to provide a more accurate emulation of reverb mode 3 ("stereo tapped delay") only. It hasn't been hooked up yet because it's not yet properly tuned. We have an uncommitted replacement for freeverb for the other modes, but this also …

Hi h-a-l-9000, Coincidentally, through some driver tweaking I finally got my digital capture device working reliably yesterday. It's a µChameleon from http://www.starting-point-systems.com/ with a custom test firmware from the manufacturer. The input to the DAC is 16(ish)-bit samples at 256kHz (8 …

Hi sergm! I only just became aware of these developments, and it's awesome to see some new people interested in the development side of MT-32 emulation. Although signs may point to the contrary (19 months without a commit...), the Munt project isn't dead. We even have a few things on the burner: - …

You can also subscribe to the CVS commit mailouts or browse the archives. We're still making steady progress on accuracy before we focus on optimisation again. The current code needs a fairly beefy system to run in realtime without stuttering.

Exciting! Will linux users be able to build this and the alsa driver module with something other than gcc3.3? (I hope, I hope ) Very Happy I certainly hope so. Linux is my primary development platform right now. I haven't compiled the ALSA driver recently (I've mostly been using the new mt32emu_ …

Quick update on this: The project is very much alive. Mok (who posted some interesting tidbits on this forum a while ago) has provided a powerful shot in the arm to the project. He's been providing us with an endless stream of insights into the MT-32's inner workings - I'm having a lot of trouble …
