Re: How do I feed mt32emu with data?

Posted on 2016-01-26, 14:56

What is the format of the MIDI data that MidiStreamParser parses? In other words, what exactly is it useful for? If I parse a MIDI file manually, should I just send the MIDI events to the play() routines with appropriately calculated timestamps, or should I use MidiStreamParser to parse them first? …

Hand-written SSE should always be the last resort. Making sure data in hot loops always fits in the 64 byte CPU cache line and reducing data dependencies (so that the CPU core can auto-paralellize the code) is the most maintenance-friendly way of optimization. Also, SSE code is the best way to …

Removing the flushMIDIQueue() call makes it produce sound. Just random notes though, they go on for 10 seconds or so and then silence. I had hoped this to be as easy as libfluidsynth, haha :lol: (You feed it the MIDI data from the file you want to play and it just... renders it. It recognizes the …

Hm, I thought the Synth would know how to time the events properly. I looked into the smf2wav sources, but they're using libsmf 😒 Does the library do the timing, or do I have to do it manually by examining the MIDI events? (I have no idea about MIDI, so I'll have to learn that one first 😜)

How do I feed mt32emu with data?

Hello, and thanks (again!) for this project. It's been a while since I posted here. Been using Munt for a long time now to play some classic DOS games. By now I can't tell the difference anymore to the actual hardware. :happy: I decided to use the mt32emu library in one of my own projects. But I …

Re: Sysex write to unrecognised address

First, thanks for your kind words. :) I really hope we'll see the day when Munt will sound precisely and really *indistinguishable* to the real things, but unfortunately, not today. Still, when I switched from the ScummVM MT-32 emu (old version of Munt I think?) to the newest Munt Git master, I was …

First, I'd like to thank you guys for the absolutely incredible work on Munt! It sounds amazing! Especially the high-profile games (see "Monkey Island") sound indistinguishable to the real thing. I spotted a possible issue with "Heart of China", where Munt (mt32d under Linux using the ALSA driver), …

Re: MIDI doesn't work on its own

I found out that there's a software synth that seems to work better then Timidity and is able to work as an ALSA sequencer: Fluidsynth. I just installed that, along with a very nice GUI for it, "QSynth", which allows very easy control of all settings. I must say the sound quality seems better than …

Re: Scaling doesn't work with "vgaonly"

Posted on 2010-10-15, 22:56

I was able to work around the issue by disabling the percentage mode (which is the default with cycles=auto and non real-mode games) and use fixed CPU cycles (about 20000 seem to work fine). 😜 Note that with percentage mode, *any* percentage has the problem, no matter if 10% or 105%.

Re: Scaling doesn't work with "vgaonly"

Yep, I tried every svga_ option available. With all of them, moving the mouse makes DOSBox go totally idle (nearly 0% CPU) and as a result the game stalls. It's the only game where this happens. Anyway, the actual issue is why "vgaonly" has a fixed output size and isn't scaled, which is puzzling.
