I have been able to search and replace cymbals from EZdrummer into SD3 but some seem to be panned more left or more right. It does not matter where I put them on the kit. Their panning seems to stay the same. It’s really strange.
the Cymbals are recorded at their position in the Stereo OH’s, not as individual Mono microphones. Unless you are using one of the more electronic oriented EZX:s, they will be added by Default to the OH at their recorded position.
You can create new mixer channels for your replaced Cymbals which will give you separate fader/pan control per Cymbal.
