New magic music added after G15 update is very powerful if you utilize them in the right situation. It shines the most in some of the harder missions and dungeons as they provide very powerful buff. Here are some informations abou them.
here is more detailed information on the music and its effectiveness for each ranks.
All the above is probably informationt that most people know already. Here is the real tip.
This music have maximum of 60 seconds playtime(regardless how long you your scroll is composed) with each effect activating every 10 second marks. However, do note that you will NOT activate the effect at the 60 second mark. This means that you have total of 5 times that effects will renew each count. This also means that you would waste 10 seconds by playing the scroll all the way through. You only need to play through 50 second mark to use the scroll to its maximum effectiveness each count. To provide continuous buff for more then 50 seconds, simply cancel the music immediately after 50 second mark and restart immediately. In order to keep track of 50 second mark, use the following MML code.
Melody: V15T60L1.RRRRRRRRR2C
Chord I: V15L1.RRRRRRRRR2E
Chord II: V15L1.RRRRRRRRR2G
It will play silent notes (so it won't annoy every in the party) until 50 second mark and plays C-note at maximum volume precisely at 50 second mark. To change alert sound, change C to desired note
This provides easier way to keep track of effects for both the bard and the party members.
