Physically-Modelled Drum is a straightforward virtual instrument that simulates a rectangular drum membrane using physical modeling techniques. It offers an intuitive interface where each control reflects a real-world physical property of the drum, allowing users to shape the sound by adjusting parameters such as membrane stiffness and mass.

Users can manipulate initial membrane displacement to influence the drum's attack, while viscosity controls the damping effect caused by air friction, which can be reduced to zero for a sustained tone. The output is derived from a specific point within a 5x5 grid of nodes that represent the membrane, giving precise control over the character of the drum sound.

The plugin employs a damped mass-spring system to create realistic drum sounds through physical modeling. This approach captures the dynamics of a vibrating membrane with a network of interconnected nodes, providing a unique and expressive drum synthesis experience that blends simplicity with acoustic authenticity.
