Multi II

The ACL Multi II is a 'multiple' module for connecting single audio or CV sources to multiple destinations. It has a wide variety of applications, such as precise synchronised control of multiple tone-generating VCO modules, simultaneous control of multiple VCF modules with a single envelope module, and many more creative modulation-related uses. All this is made possible because the module actually contains two discrete modules, one passive and one active. The non-buffered passive section distributes one input signal to up to six freely interchangeable outputs. The buffered active section has two high-impedance inputs, one inverting and one non-inverting, and five low-impedance outputs: its main purpose is to stabilise the pitch of up to five VCO modules, and since a second signal can be added or subtracted, it also works as a mixer or subtractor for CV and audio. Precision low-tolerance resistors and low-noise, low-drift operational amplifiers keep every copy of the incoming signal in tune.
