Programmer Instrument and Sidechain

Hi, I made a programmer instrument for a character’s dialogue, I’m looking to stop the event once the programmer instrument has finished. These are the steps I took:

1_create a sidechain effect on the programmer instrument’s track
2_add a parameter to the event
3_add a sidechain modulator to this parameter, with input the programmer instrument track with sidechain
4_I have added an automation to the parameter sidechain modulator Amount, where 0 is 0% and 1 is 100%.

Can you help me?

A non-persistent event automatically stops when there is no further content on the timeline and no content of the event is currently playing.

I do not understand why you need a sidechain and a parameter; they will not change this behavior.
