2HP Rnd Black is a random module for modular synthesizers in Eurorack format. The module is a random generator and a random gate source with an internal clock. The output is a quantized random voltage between 0V and 10V. The attenuator control provides a fine tuning of the random voltage. In this way, a musically meaningful area can be defined. In addition, random gates are emitted from the gate output with an associated probability control while they are clocked externally.
