The Disaster Area Designs SMARTClock controller pedal sends both MIDI clock and analog tap tempo signals through isolated outputs. This intelligent pedal can work with normally-open or normally-closed (Boss) pedals, and the tempo output can also be used as a non-tap expression or function switch. Two switchable modes let you use the footswitch to tap in the timing or bank through preset tempos as you work your way through your set -- up to 128 presets can be accessed with an external MIDI controller.
