Thank you svennilenni & Elien for your replies.
I checked my drum track folder (which contains Kick, Snare, Toms, etc…) and noticed it is a regular Folder, it is not a Group folder.
My drum kit has different outputs for each element of the drum kits (Kick, Snare, Toms, etc…).
What I want to do is, to Mute completely my drum (Kick, snare Toms, etc…) for about 20 measures in the middle of my song and then Unmute.
Q 1- Is it possible to achieve this by moving my drum into a Group folder?
In Arranger window I tried to crate a Group folder and drag/drop my drums into it , but it’s not working.
Q 2- How can I move my drum into a Group folder in Arranger window in order to use Automation or further controls for individual drum’s instrument later in my project?
