A multiple is a module that allows users to split an input signal into multiple outputs. This allows the user to send the same signal to multiple destinations, such as multiple oscillators or filters, without the need for additional patch cables or signal sources.
Multiples typically feature multiple jacks, allowing for the splitting of a signal into two, three, or more outputs. Some multiples may also include attenuators or inverters for further signal processing. Multiples are a simple but essential component of modular synthesizers, allowing for efficient and flexible signal routing.
