From the developer:
Scratchy is a standalone virtual instrument for Mac that produces noise. This noise can be manipulated by a tempo-synced gating effect (at various degrees of note length), by a filter cutoff control to adjust the pitch and by various other effects. The result is something akin to scratching.
