Though many consider noise to be an undesirable and unwanted nuisance, synthesists know its value as a source of breathy nuance, crackling sizzle, chaotic roars and subtle silkiness. When applied effectively, it can add that touch of the unexpected and the random, which brings a patch to life.

Noise Tools provides this essential dose of randomness in three blocks. First is a Pulse output, switchable between a steady clock or a random flurry of gates. Second is a sample and hold circuit. Third is a slew limiter. The blocks feed each other from left to right, but feature inputs to break this normalling, providing a useful balance of functionality and flexibility.
