	Yes. The midi playback gets very distorted if you tab out and back to the window especially during combat. ~~Saving~~-exit-reload will fix the problem ~~for that instance~~. One of the main issues is with the type of midi synth that your system uses. Some people seem to have one the data for the midi file seems to like, while others have different instruments for the same values and thus the sound is horrible. It seems that many of the tracks in the midi files are set to 00 (01?) which is a grand piano in the default microsoft synth table.

At the very least, it was a significant improvement over what was previously playing.		Yes. The midi playback gets very distorted if you tab out and back to the window especially during combat.

			The two geoscape sequences really consist of four songs that are about 4 minutes each. The PSX version splits these into the individual tracks. Also the adlib.cat, gm.cat and roland.cat files, if I'm not mistaken, contain the complete set of music in each file but are set up to work for their respective sound card types. Most Sound Blaster users will have been listening to the adlib.cat sequences. - [[User:NKF\|NKF]] 22:31, 8 June 2008 (PDT)

			:Thanks for the userpage, Seb! :) I have a (probably very silly) project I could use some advice with.

			:I want to give the DOS version of X-COM the ability to play the [http://www.xcomufo.com/x1music.html excellent CD music] from the PlayStation version. X-COM DOS plays its music through a TSR called MUSIC.COM in the SOUND subdirectory, which is loaded into memory when X-COM is started and then receives commands from it somehow. I've found a TSR CD player, [ftp://ftp.externet.hu/pub/mirror/sac/sound/pci-mcd5.zip Mercury Soft CD Player], that works in DOSBox and runs fine with X-COM, and if copied over SOUND.COM, X-COM will automatically start it and it responds to its hotkeys properly. I figure all that's left to do is disassemble SOUND.COM, figure out how it receives its signals, then disassemble MCD and modify it to respond to those same signals.

			:Of course, that's probably the hardest part :) It helps that both SOUND.COM and MCD.COM are less than 4K each, but my experience with assembler is very slim and many years out of date. You suggested using [http://en.wikipedia.org/wiki/Interactive_Disassembler IDA] in the Grenade discussion, so I'll be giving that a look. Any other suggestions or advice to get me started? [[User:Phasma Felis\|Phasma Felis]] 20:46, 6 June 2008 (PDT)

			::The way it works in the CE version is still influenced by this. Only the mouse, video and sound code was wrapped with windows calls; the rest was left as-is. All the sound related operations are centralized in one procedure taking 3 arguments. The first that I dubbed 'opcode', and 2 others that are not used (but may be of use in the DOS version). I suspect that in DOS version these arguments are passed to the TSR by some way to trigger sound actions. Here are the details I know from the CE edition:

			::* if the opcode is >0x7f (i.e. the most significant bit is set), then it is a music change request (translated into a 'play midi' sequence in the CE edition), else it is a digitized sound that will be played

			::* the music sample number is extracted by removing the high bit (opcode-0x80)

			::* cases 1,5 and 14-17 stop the music but don't start a new sequence

			::* for other cases, it starts playing a midi file (and stops the current playing if any):
			::{\|
			! Sample idx \|\| Sound file
			\|-
			\| 0 \|\| sound/gmgeo1.mid
			\|-
			\| 2 \|\| sound/gminter.mid
			\|-
			\| 3,4 \|\| sound/gmdefend.mid
			\|-
			\| 6,7 \|\| sound/gmenbase.mid
			\|-
			\| 8 \|\| sound/gmmars.mid
			\|-
			\| 9,12 \|\| sound/gmstory.mid
			\|-
			\| 10 \|\| sound/gmlose.mid
			\|-
			\| 11 \|\| sound/gmwin.mid
			\|-
			\| 13 \|\| sound/gmtactic.mid
			\|-
			\| 18 \|\| sound/gmgeo2.mid
			\|}
			::You need to get this sample idx and remap it to the PSX track you want to play. I don't know if you can map all PSX tracks.
			::PS: What is the 'official' way of moving this to the talk page... Cut/Paste? [[User:Seb76\|Seb76]] 04:11, 7 June 2008 (PDT)
			::Edit: I could grab a DOS version of XCom and noticed there are no mid files in the first place so this won't be useful if you want to patch the DOS version. [[User:Seb76\|Seb76]] 11:53, 7 June 2008 (PDT)

			:Awesome! Thanks very much, I think this will help. The music in the DOS version is all stored in two files (ADLIB.CAT and GM.CAT), but I'll bet the indexes are the same. Most of the PSX tracks map well; there's a few oddities, and it has two extra Geoscape tracks and one extra Battlescape, but I'll probably just choose those randomly each time (I'm tentatively thinking that the two least-significant bits of the system clock should work, and hopefully be easier to implement than a proper RNG).

			:P.S. I think cut/paste should be fine for moving it to the Sound talk page (I think that's what you meant). Just be sure to give it an appropriate heading. :) [[User:Phasma Felis\|Phasma Felis]] 19:51, 7 June 2008 (PDT)
