Guild Wars 2

I noticed a change to my harp last night and tried out other instruments. Instruments now seem to loop their sound when the key is held down. It’s a slow loop. It seems to be tied to the length of the instrument’s note sound. The bass has a longer loop.

Before there would be no looping sound when you held the key down.

Is this an intended change or a bug that snuck in?

I would say that it is a bug. The patch came with a skill change where holding the key would activate the skill soon as it was available. Since instruments don’t have cool downs, it just constantly loops the note until release.
