Hello there, I will try to explain you my problem. Sorry for my English.
I create FX Channel to connected it with a vocal channel.
https://prnt.sc/fu8tme
At the mute point’s of fx the origilan signal of channel “main vocals” is ok. If the song goes to the fx delay point’s I hear the delay but the “main vocals” volume up.
(Listen this please and you will see.)
