Anyone have any idea why that would happen? It's super frustrating. It seems to happen randomly where I will pan one track or add a certain effect and then I immediately notice Maschine applied the same things to another track or tracks.
Could it be that you accidentally selected several tracks, like in this example?
As you can see there are 4 tracks high lighted, this means that if you move the volume or pan for one it will affect all highlighted channels. On a Mac you simply need to click with CMD the channe you want to add or remove from selection.
