Oh, I'm pretty sure now it's due to my USB MIDI interface. I don't think it's broken though, rather it's too fast for the poor old MT-32
hoot player works. Just like that, never had any real problems with it.
DOSBox works only when slowed down to a crawl, or with the SysEx throttling system introduced in SVN. The reason this got added is because many people had problems similar to mine, and asked for help on VOGONS forum.
ScummVM doesn't work properly for me and there is no way, as far as I know, to slow down SysEx data sent to MT-32. All I'm asking for is a system like in DOSBox, doesn't even need to be a GUI option, I can work with config files just fine.
I do realize that there are MIDI cables out there that "just work". No idea why, maybe those have built-in SysEx throttling or are simply somewhat slower in general. One such cable was close to being made obsolete when the manufacturer got very tardy with x64 driver for Vista and Windows 7. So, should we all get a "compatible" interface that might just stop working come next Windows version, or wouldn't it be better to add a software workaround for new hardware to ScummVM?
And yes, I do have another, cheap USB MIDI interface but that one never quite worked right. I also have SB128 soundcard with MIDI output but it's no longer supported in x64 systems. I can test it on XP machine but even if it works well, that doesn't really help me in any way.
