When you make a group and send the sub track to a bus, after you edit the Folder (Ableton calls it group) the busses level doesn't change regards to folder. so I manually need to route the output of a bus to the folder I want, but when I do that, I can't use that bus with another channel becuse when I change the volume of the folder, bus volume changes for other tracks too.
In ableton when you want to use a reverb for both tracks you send a reverb bus to a channel. When you change the amount of send, ıt only effects that track, not the whole send track. I know It sound a little complicated when reading this but Ableton users will understand this, It was such a time saver. I would love to see this in S1 too.
