I don’t have much to say on the matter, I love that they implemented this feature, but I feel like playing it feels too clunky and lacks precision.
I know ANet loves to be unique but for once I wish they could do what Mabinogi did and use the MML system.

Perhaps keep the existing instruments as they are and release on the gemstore an MML version-ed instrument, MML’s are more precise and diverse, they’re fun to play with!
Perhaps even link this with a crafting discipline that increases every time you play to get better? anyhow, just an idea.
