Ezdrummer should separate the instuments as you want. Here is the procedure for EZD2. Not sure which version you have but the procedure might be similar for EZD1…
Working on an “Instrument” track:
- Open your EZD2 and go to the “mixer” tab.
- There, you can choose where each instrument channel will appear in Cubase
- Choose the dropdown on the 1st channel (the one on the left) and choose “multichannel”. That will assign a separate track to each percussion instrument.
