Converting a gate signal, for example a midi gate or the mouse button output of a mouse area, to a trigger signal can be used to trigger an envelope, to store a value into a snap value, etc...
This can be achieved using a stepfilter with a threshold of 0.
GateValue -> StpFlt.In StpFlt.Out -> TriggerSignal StpFlt.Tol
Another way to achieve this is to use a Separator combined with a stepfilter. This can be useful to separate the two-levels of the gate signal into separate signals.
GateValue -> Separator.In Separator.Hi -> HighValueTrigger Separator.Thld Separator.Lo -> LowValueTrigger
