When I put Loopy Pro as an effect in the fx slot of AUM it is not possible to open my usual effects in the Loopy Pro mixer. I just see Loopys effects (Bandpass, Dynamics, etc) but unfortunately nothing else. Do I miss something ...?
Nope, you’re not missing anything. You can’t host an audio unit within an audio unit. If you want to host within LP, you need to use it standalone.
