The Stop Device
The Stop device provides a mechanism for producing specific pitches from a string by stopping or fretting it, i.e. temporarily changing its effective vibrating length. The Stop device is not an entirely accurate model of how a stopped string behaves and will probably be refined in future releases. It currently works by installing a Connector device between the specified access point and a fixed anchor position at 0.0. This restricts the vibrations of the string at the access point. In addition there is a `damping' attribute which causes a small region around the access point to be more highly damped than the rest of the string. This causes the string to almost stand still at the access point, which is the desired effect.
