I use my DAW to export MIDI files (I complie the MIDI files in the DAW, whether that be EZ Drummer, or other) and then send them as an attachment via email. I use Google Drive for storage, but would imagine the process is pretty much the same for DropBox.
EZdrummer version: 2.1.8 Operating system: Windows 10
