Stop effect

Either give that effect an exit time or use cue parts.

The exit time can be set in the effect editor (effect effect), on the right hand side of the CIA you find then entry and exit behaviour. Where it currently says Cue/Sub you can also enter a time.

Or you put the channels with the effect in their own part. This is a little tricky as an effect currently always uses the In time of cue part 1.

Does this help?

Brilliant thanks
