No, Using the Note_On (rather than the One-Shot LFO) is just a way to be able to set a pause by using the Length pipe. You then use the Note_Off to Transform to an “Un-Bypass” mapping. I don’t often use it as a technique cos you have to take extra filter measures if the pipeline has notes flowing through it.
Actually, as you only need an On|Off, try playing with One-Shot Square or PCM
I tend to think of toggle as 2 separate external actions.
(described here in Virtual Mappings Techniques topic)
Here we’re talking On → pause → Off from 1 external action by using the techniques hinted at.
Happy to sketch it for you or to give screenshot hint but don’t want to steal the fun of creating it yourself! Lemme know…
