I got a request to built a broadcast with the option of being able to sync the tap tempo part of the lfo with an external click instead of taping a switch. There’s a jack on tap where a cable is plugged with the click or a metronome, and when the pedal is in tap mode it will sync (and re-sync so it will stay with the beat), when nothing is plugged in the jack there’s a tap switch available. Other stuff was the invert toggle switch, it changes the sweep direction (so when the wave was up it will be down and vice versa), Exp/CV IN for manual sweep and control of the rate/tap ratios and also the range. CV out to expand via the broadband and bandwidth for more options.
