In case if anyone is searching for this, I've converted the EZDrummer 3 MIDI map into a Studio One pitch list, so now you can have your EZDrummer drum names in the editor window. Tested on Studio One 6.
Just save the text below as "EZDrummer 3.pitchlist" in your "Pitch Names" folder ("USERNAME\Documents\Studio One\Presets\User Presets\Pitch Names\" by default on Windows).
