$22Mult is a passive multiple to send one signal to multiple destinations. While there are tradeoffs between passive and active mults, a passive mult is generally a good choice for audio, envelopes, or LFOs.
Mult is only available as a DIY kit. With only 4 parts and no power, Mult makes an excellent introduction to DIY. No power means no “magic smoke” when you make a mistake. Comes with everything you need. Just add solder.
