Scratchy is a standalone virtual instrument for Mac and PC 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. It can be controlled by keyboard / mouse, but it’s recommended that you use a MIDI Controller. Templates are provided for TouchOSC and Lemur so you can control Scratchy with your iPad / iPhone More
