I have a simple template for using MG3 hex in Live (see attatched image) but can see myself still needing to reroute things on occasion. I guess it’s just a personal workflow thing.
Also, particularly on macOS, it will mean you can use whichever version of the plugin you prefer in any DAW. I’m pretty sure you can’t do the above in Logic, for example.
Installing a PC running MG3 onboard an instrument sounds interesting!
