SetResetFF

A flip-flop UGen with two inputs, one (set) triggering an output of 1.0, the other (reset) triggering an output of 0.0. Subsequent triggers happening within the same input slot have no effect. If both inputs receive a trigger at the same time, the ''reset'' input takes precedence.

===Examples===

// mouse-button toggle
play {
 // make sure lag is zero, otherwise the output
 // never falls back exactly to zero!
 val set   = MouseButton.kr(lag = 0)
 val reset = Impulse.kr(1)
 val ff    = SetResetFF.kr(set, reset)
 SinOsc.ar(ff.mulAdd(400, 800)) * 0.1
}

// limit trigger rate
play {
 // with a combination of TDelay and SetResetFF
 // we can build a filter that lets triggers
 // pass at a maximum rate.
 val dur   = 1.0  // minimum spacing between triggers
 val in    = Dust.ar(10)  // high frequency trigger
 val lim   = SetResetFF.ar(in, TDelay.ar(in, dur))
 val time  = Timer.ar(lim)
 time.poll(lim, "bang")
 ()
}
