Primitive as it may be, the most complex Eurorack synth rigs rely on modest mults like Doepfer's A-180-2 signal splitter module. This passive multiples splitter features two groups of four ports, allowing you to split two different signals to three different sources each. That's incredibly handy when you need to send CV and Gate to three other modules. By the way, here's a tip from the modular synth guys at Sweetwater: if you find yourself in need of an 8-fold mult, and you happen to be handy with a soldering iron, then you can modify your A-180-2 by bridging jacks 4 and 5 together on the back.*
