"The later Vanilla Doom versions added support for MIDI files, which meant WAD authors no longer needed to convert MIDI files to MUS." Can anyone verify that older vanilla doom versions are not capable of playing midi-files? And if so, at which version was the midi capability added? Anders A

I was under the impression that no vanilla doom supported midi files directly. Unfortunately, poking around to confirm this didn't find me much. Because the original sound code was gutted for the source release, looking at linuxdoom-1.10 or another source port probably wouldn't help much, and I'm not very familiar with the sound code layout anyway. But, I did notice that the original BOOM documentation mentions midi support under "Wad extensions in BOOM phase I", and BOOMEDIT.WAD also mentions the ability to use midis directly as a boom feature, which suggests that it was not available vanilla. Hopefully someone else knows more. 02:36, 17 September 2007 (UTC)
no vanilla doom supported midi files directly   There was a recent forum thread about this at Doomworld, believe it or not.  I'll see if I can find it.    Ryan W 03:44, 17 September 2007 (UTC)
This isn't the one I remember reading, but it (and the links people posted) appear to address the issue.    Ryan W 04:22, 17 September 2007 (UTC)
My own experimentation has shown that it is possible to put MID files into Vanilla Doom directly. However, it only works on certain files; some files don't play. I haven't been able to determine what the exact criteria is for what works and what doesn't, except that large files won't play. Fraggle 07:51, 18 September 2007 (UTC)
Yes, that vanilla doom can play midi files is a well known fact (or has been for the last couple of years anyway). I'm just wondering where the claim of older versions not beeing able to comes from. If noone can back this it should be removed from the article, or perhaps changed to something along the lines of "It was recently discovered that... " instead of the current "Later vanilla doom versions... " Anders A 11:51, 19 September 2007 (UTC)
You could get the 1.9->1.1 downgrade patch from and try out some midis in it. I'm not sure where to find 1.1->1.2,1.3,1.4 at this point. 13:22, 19 September 2007 (UTC)
Did some testing using the downgrade patch. unfortunately the only upgrade-patches i could find was 1.1->1.2 and 1.2->1.666, 1.1 and 1.2 did not play midi-files while 1.666 did. if someone can get hold of the versions in between 1.2 and 1.666 the version where this was introduced can easily be found.

Size limit[edit]

This thread at Doomworld claims that a WAD can contain MUS files bigger than 65536 bytes.    Ryan W 18:10, 26 January 2008 (UTC)
