So for channels with drum sequencers, the ability to add Multiple midi lanes. I used this alot in Reason, it just made drum creation easier, just copy and paste clips with drum groups. So i can cut hats off or snares. or just drop a role or an FX clip without having to edit an already existing clip. was really fast way to add complexity to my drums with out having to edit 20 different clips where i lose track of edits, instead i can see the blocs in the different midi lanes, and i know this lane is snare/clap/kicks, this lane is hats symbols, this lane Tom roles, or FX.
Also Say you were to label a midi clip and Copy it, Would be great if any changes made to any one of the clips would be reflected to other with the same label.
