Hey Anet, I recently (a few weeks ago) got a musical harp to play with a few friends but all of us have been experiencing some major delays and disruptions in playing anything quickly.
At time the sound doesn’t come out, or pauses then comes out in a massive cluster. This is true for thee Lute, Flute, Bell and Harp. Its gradually been getting worse and others have told me that they too are experiencing this.
