Switch, Split and/or Join
A signal multiplier accepts an input signal and routes it to multiple outputs simultaneously. For example, you might want a sequencer’s GATE to trigger two different envelopes — one to control volume and one to control filter frequency. In order to accomplish this, you need a signal multiplier.
In addition, each Switched Mult 1U features a pair of 3-pin Link connectors on the rear panel. These let you connect other 3-pin Link devices, such as an XY I/O 1U module, or even additional Switched Mult 1U modules (handy for distributing mults across the width of your case).
