Click the Object 1 button to deselect it while you are repeatedly striking a key. The sound stops after Object 1 is deselected. The string itself doesn’t make a sound unless it is stimulated by at least one object. Click the button again to reactivate it.
Choose each menu item from the Object 1 Type pop-up menu. Strike a note repeatedly while you choose each item to hear the impact of each object type on the string. Keep an eye on the string animation. Note that Object 1 can make use of excite types only. Object 2 can make use of either excite or damping types. Object 3 can make use of damping types only.
Adjust the Strength knob by dragging vertically for large changes or horizontally for fine adjustments. Strike a note repeatedly while doing so.
Drag the Timbre and VeloSens arrowheads to different positions while striking a key to audition the changes that they bring.
The impact of the Variation parameter is different for each type of object. Feel free to experiment with this as well.
Try out each of the Gate settings.
