this song was mad, link?

Finally! Thanks man. Big help!

Very helpful! thank you!

how to select all mixer channels in fl studio 11

I grouped my tracks to a new chanel but there is no sound going through the new track they are linked to.
It shows the green wires so it's connected but the new track doesn't play the grouped tracks audio.

Do you know why this is?

Thankz ! Nice and straight to the point 👍
