I was using aaltoverb with 32lives in Logic 64-bit. It no longer works in Sierra. :/
Sorry to hear that. I'm looking to the future here and will release a new free option before long.
Wow, that would be incredible. I miss that little plugin.
In the meantime I have finally had time to seriously experiment with Virta and I'm still trying to pick my jaw off the floor. It is a true gem.
