Ykhwong's used in the DOSBox patch the latest sources published at GitHub. There are changes in sawtooth wave generator compared to that binary you have tried early. But as you can hear, these still don't make the MUNT sounding correct.

I just tried Ykhwong's DosBox too. Great version but which version of the new MT-32 emulation is it? Legend of Kyrandia is sounding wrong again (and Budokan too), when it sounds great with the version I downloaded from the Munt Reloaded site two weeks ago. Anyway, great work!!! Gentlemen, please be …

Hello I am new here and I just installed munt on my computer. I am wanting to make some original music using munt instead of the defaunt Microsoft midi out. Is this possible and if so what is the best software sequencer to use. I am making a game using Adventure Game Studio and I want to give my …

I've made a CLR version of my mt32emu_win32app just for fun... Its cool features include the possibility for on-the-fly parameter applying (such as samplerate and latency). And the master volume can be changed with a gain factor up to 10 😉

But alas, partial volume now is an issue again. Normalization needs to be turned on. Basically, this is misleading way indeed. Now, we discuss several new approaches to wave generation, but this is another story... Found the cause. Filter was set to a half-frequency for sawtooth and thus attenuated …

Please keep us posted with the progress you make. Corrected wrong sounding of SynBrasses in Police Quest 2 intro theme reported by Ykhwong. There was incorrect handling of pulsewidth parameter for sawtooth waves. Those SynBrasses sounds 1 octave upper then needed. BTW, the current sources are moved …

I am not going to incorporate your library to my release right now. As mentioned above, I don't like that it still sounds weird in Police Quest 2. Corrected.

Yesterday, KingGuppy was so kind and made me a member of MUNT project. Many of my proposed changes are going to be committed into the MUNT or at least in a separate branch. So, development of Munt Reloaded will surely be closed. I'm sure the upcoming release of MUNT will be appreciated.

Sorry if this is off-topic, but I think you mentioned that you don't currently have a physical MT-32 module. There's an auction right now on eBay offering one: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250783976543 That ships internationally, if you are interested. Regards. Thanks, Leolo, …

P.S. KingGuppy, I do compile MUNT Reloaded releases with VS2008 Express. I've installed WinDDK and grab 2 more files for dmusic (dmplugin.h & dmusici.h) it lacks. Also I updated the project files accordingly. P.P.S. I'll simply remove my project as soon as you can grand me membership in MUNT. …

Hi! I don't even expect hearing from you, KingGuppy, as my first (and my bad the single) attempt to join as a MUNT developer was failed approx. a month ago. And, of course, I'd be happy to do this. The "fork" (more accurate to say "a long waited release") was made as a simple way to share it with …

I agree with everything you've described here. Even with a square wave generator, those can be made by subtracting sawtooth points given a particular pulse width. The mystery remains, however, where did those samples come from to start? They aren't found on any of the ROMs. Oops, the …

One more idea on improving sounding for partials with cutoff < 50: in this case we can bypass filtering at all and utilize an exact law that MT-32 use for the wave attenuation. Here the patch for partial.cpp: ... Bit32s filtval = getFiltEnvelope(); float freqsum = synth->tables.tCutoffFreq[filtval] …

Playing with my new wavetable WG I've noticed that when using IIR (even bi-directional) the waves generated are never symmetrical. They clearly differ in positive and negative semi-periods since the infinite filter response. So, perfect waves (as I suppose MT-32 generates) can be made only using FIR …

Yes, maybe because of not much speed of MUNT. P.S. I've also noticed, DOSBox eats significantly more CPU than DM driver I've built on MUNT CVS code. I suppose this is due to more overhead in calls to render(). DM driver calls render() in between of playmsg() calls and use timestamping to preserve …

I had this on my TODO list for a while now...changing DOSBox patch so it could have Munt in separate dir... :happy: It's great, Gulikoza. BTW, maybe there is a need to enqueue timestamped MIDI messages in the buffer in order to render them in time. I've noticed a minor desynchronization listening …
