Bug with FilterMax
I'm sure you are already aware of it from the livestream today, but FilterMax has a bug. Narrowed it down to using "EQ: Peak", "EQ: LoShelf" or "EQ: HiShelf" and setting the gain <= 0. The sound will come back once you pass 0 again.
Ableton Live 10, Omnisphere, Native Instruments (Pianos), Spire, Diva, SynthMaster, Alchemy 1.55, Addictive Keys, Unify
Thank you for making a note of this. I was too busy during the livestream.
This bug will be fixed in the next release!
