Two voltage controlled single pole quad throw (SP4T) switches

The Dual Sequential Switch module from Fonitronik allows you to route Audio or CV sequentially from one source to four destinations or the other way around. You can do this either manually using the momentary switches, or using a clock signal. The clock signal moves the switch one step forward, the reset signal puts the switch back to step 1. The clock, reset, and main I/O inputs can be normalled, either from left to right or v.v.
