Yes, Guitar Mods will be a separate AUv3/App on TestFlight. It can be used with other apps just like MG3, but its highly experimental still.
And then there is some sneaky integration going on: MG3 (from this version and onwards) should (fingers crossed) notice the Guitar Mods AUv3 and can actually render Mods modules natively and they work just like the MG3 modules.
This allows me to make all sorts of experiments and not bother the majority of MG users ![]()
