I have ezdrummer and ableton live.. I was wondering how to cancel things out ..like take the ride only then build up the other parts. do I have to open a new ezdrummer window for every part?
From a midi point of view you should be able to do it all in 1 Instance of EZ.
In logic i may open as many lanes or tracks assigned to any instrument and build parts one by one if needed.
You should have a midi piano type of editor and select,mute delete add anything you want on an existing midi file or region(s).
However if you want a specific extra sound in EZ , perhaps from another EZx, no harm in opening another EZdrummer too.
