Triggering outboard synths with MG

Would love to hear about anyone’s experience with sending midi out from MG to outboard synths/modules with a midi or usb in.

I use sometimes an external midi device when i can’t find appropriate sounds in my vsti set.
Playing a guitar on a korg triton creates a great feeling, and I have fun playing a korg volca bass.
I select my audio card in MG’s midi interface output and connect my devices on midi output from audio card. It works fine, no adjustements needed and obviously no latency.
But, as for on-board plugins, the most difficult issue is to trig correctly with guitar, and each vsti or external synth might require fine adjustments (see MG settings for gain, tone…).
