Switches, mutes and utilities are the secret sauce of a modular system, big or small a system can always benefit from utilities are it makes the other modules shine. Here’s a great example of that with the Molten Bypass from Molten Modular & Befaco. It takes a stereo input, adds an insert point (TO FX and FROM FX) and allows you to bypass/enable that with or without trails and with gated or latched behaviour.
