How aleph one handles music

[kandriod]

I am wanting to implement my own M1 music folder that contains the marathon CD soundtrack as well as the tracks that weren't remixed in it. However I cannot figure it out and I tried the chibi USA soundtrack on simplici7y to get an idea of how this works but it didn't work despite me following all instruction, I also found that removing the games normal music folder from the marathon directory entirely will still have the original music function when you play it. I would like to know how to do this.

Marathon 1 handled music differently than how Aleph One later implemented music. Now that Aleph One can play stock Marathon 1 and doesn't need a port (like M1A1) I imagine it is playing music from M1's "Music" file, which basically contains a bunch of MIDI songs, rather than playing from an external folder of regular audio files like every other scenario does.

So I expect that to change the music in M1 (even playing it through Aleph One now), you would need some way to compile a replacement Music file.

Original Marathon music is specified by the indexes in the map file. Aleph One looks in a Music directory for files that match the index, so for example it looks for 01.ogg then 01.mp3 for levels that ask for track 1.

So you just need to replace the files in the Music directory.

I replaced the music directory with a new one that had renamed tracks but it still played the normal music. Is there something more to the newest aleph one that needs to be changed or enabled?

[treellama]

I don’t see how it could be playing the old music if you replaced it. Double check that you replaced the right music folder.

[kandriod]

There is only a single folder called music, I am certain I replaced the correct one.

[treellama]

Then what music is it playing back? It has to be coming from somewhere...

[kandriod]

I know right? I don't know how it plays the original music when it's outside of the marathon directory.

Are you using a Mac? If you're using the Marathon app, it has the data files built in. So you'd have to show package contents, and find the music folder inside there.

If you're using Windows, then I am confused as heck. I guess technically it will search in your user data directory...on the unlikely chance you installed some music to Documents/AlephOne

[kandriod]

I am using windows. Maybe I should use the M1 data files with the aleph one standalone download and see how that works out

[kandriod]

Well, I forgot that I screwed my copy of marathon 1 by turning stereo off which crashes the newest aleph one. Also by the looks of it this solution of using the M1 data with an aleph one engine standalone download wont work.

[treellama]

It should work, but it will behave the same as far as music goes. You can delete (or edit) the preferences file to fix the stereo issue; the default preferences are stereo so if you remove them Aleph One should start working again. Look for them in C:\Users\username\AppData\Local\AlephOne

Thank you for the solution. Modifying M1 music on windows is a difficult task, perhaps 4 months from now I will just ask the aleph one dev to make the windows version easier to mod in terms of songs.

Treellama here is one of the Aleph One developers.

I have an idea for this easier custom music thing, like a new submenu in sound that shows a file that directs what levels play what tracks in a music folder, say you wanted the 4th song in the folder to play 4 times in a row, you list levels 1-4 as track 4 stages. In order to make a new file you make a new text file that it reads as directions, "Stage 4 = track 2", you edit the number after track to determine the slot on the folder the stage takes its song from. By default it has the correct original game config.

For M2, M∞, and A1 maps, you can already do this easily by splitting a map with Atque and looking up TEXT resource 128. Edit that, re-merge the map, and you've got a custom soundtrack.

M1 maps, on the other hand, are lacking modern editor support. You'd have to open the map in Pfhorte 1.x, open a level, go to Level > Edit Mission Info Data, and see/edit the song index, for each individual level.

I think getting our editors to handle M1 data files is a higher priority than adding a menu to the engine, which at the moment is only receiving bugfixes for the most part.

Thank you all for your input, I learned a lot! I have even made a custom Infinity OST out of various songs.
