Modulation

Perhaps one of the most exciting aspects of Eurorack is modulation! As we know, most parameters of a module can additionally to hands-on controls, be altered via control voltages (CV). These modulation signals come in many forms, such as LFOs, envelopes, random voltages, and much more. Each modulation module excels in certain tasks, and some even have their own CV inputs, allowing the modulations themselves to be modulated! The voltages used in Eurorack are typically 0V to 10V, or -5V to +5V.
