Bard Performance and... Restrictions

[StarRosie]

LOTRO allowed minstrels to be able to actually change the songs of their abilities, not just the performed songs. It was actually quite awesome, and I loved it.

Warframe has this as well. There is an entire music based frame called Octavia. You can create music with her Mandachorde and that song will play when any of her abilities are used, and knowing the song can be useful since one of her abilities needs you to perform an action in beat with the song to gain specific buffs (Shoot in beat with the song, gain increased fire rate, jump in beat with the song, get speed boost, crouch in beat with the song, turn invisible for a bit.) but yeah, the music you make is played whenever one of her abilities is used. It was pretty neat, seen some cool covers come out of such a limited music maker.
