The Noise Engineering Horologic Solum is a clock module in Eurorack format. The module works as a master clock with a built-in clock divider. An input socket also allows synchronization with an external clock. When the internal clock is used, this socket serves as CV input. Horologic Solum contains 3x tempo modes and 3x divisor modes: division by powers of 2, by odd numbers or by powers of 4.
