Correct what though ? What is it you believe is wrong about it at present

A Lock Trig (yellow) will have a Note value of zero (unlocked), it will have locks to disable Synth/Samp/Envelope/LFO retriggering and a lock for the parameter you modulated, e.g. Filt Freq

What is it about this which is not right, are you just surprised by the audible & sudden filter opening and confusing this with Trigging

what happens if you set the p-lock value of filter to be exactly the same as the current track sound value ? does it effectively vanish ?
