Record a track lane. Mute that lane. (mute button lit) Record another take/lane. Hit CTL+Z (undo). Take #2 disappears as it should. Take number 1 mute button is still lit but it will play audibly. If you double click the mute button on and off again it will then mute. Problem: track is muted but will still play. Instead of undo, as i am used to I have to hit the little x on that take. Man I wish A fix would come for all my issues! And I am not what I would consider a "Power user" so I feel sorry for the rest of you. I would like this, drum map audition (reported and confirmed bug)and mute tool fixed. Most of all I would like the vertical zoom tool in drum view fixed.(where you hold it near the top and a mag glass shows and you right click & pull down. It will crash every time. I've ragged about this before and I love X2 but I feel it was rushed and never have I seen such a release that seems to have as much broken as it has added!!
