It also means, if you use Duplex on Mixer setting, then you can control effects in many different tracks at the same time by having it set up in a Control track, thus taking away much of the MIDI Mapping side of things. You do obviously still need to set up the Hydras though. Seems like it might still help to make it a little easier mind… Native MIDI Mapping was always possible across effects on multiple tracks. This would allow you to take the Song to different setups and use/try different controllers with it much easier though. And hopefully other advantages that may not be obvious yet.
