This is how I setup up my hardware synths in Ableton,
so I can load them up fast no messing about with in & outs just drop the midi track and get on with making the music.
Some might already know this, but any way its a good tip if you don’t 
after you have setup your SUB37 MIDI track with the editor and external instrument,
just drag the track over to the USER FOLDER (I have put a folder named —HARDWARE SYNTHS in the there with all my hardware setups) just drop it in.
When you want the load the SUB37 you only need to drag and drop in ABLETON and your ready to go
Little video below to show you how fast it is
