Hi the community 
I have an issue that I have not had before:
- Track 1 -> thru machine with my modular gear in input A B -> scene A location 1
(track 1 volume up & track 2 volume down) - Track 2 -> flex machine with a sample (a recorded version of the modular) -> scene B location 16
(track 1 volume down & track 2 volume up)
The thing is when I switch to scene B to A, there is no volume on the thru machine but very slowly the sound starts coming back reaching its maximum volume progressively.
I have this issue only with the thru machine it seems…
Thanks in advance for your help.
