With the losses of the moddev JP mml site and the crash/loss of the MabiMML.org site, we mabi musicians need some long-standing and dependable resources.
The 3ML offline composer:
Make sure to get 2.0.2 build 777. The newer version is a little easier but conflicts with the HackShield. Build 777 should have 3 language options - english being one. 2.0.2 has a download link near the bottom of the page.
There used to be other offline composers for MML, but I cannot find them now.
The Vardamir Family Music Library:
This is a small collection of MML music I posted for my Mabi family. Since the family is all but disbanded, the collection should be useful to someone and has been set to public access. If traffic becomes substantial, I may add more songs from my private collection.
Mabinogi Music Scores:
This is a large collection (about 7 pages of MML) that has been sitting out in cyberspace since 2008, at least that was the last update.
There are also long lists of MML scores in various forums (including this forum's huge selection) and in the NA Composer off the Mabi main page. It helps to have an offline composer when working with those resources to clean up the songs and make sure they are workable before porting them into Mabi.
Feel free to post links to other helpful music programs or to homepage-style MML libraries. Hopefully these resources will make the loss of any large libraries less painful.
