Hello I think I found a bug with the Cremona Quartet (All 4 individual instruments). When you save a Cremona Quartet instrument, for example Stradivari Cello to the Ableton User Library, it loads back in silent. This is a new issue, as I've been loading in these instruments from the Ableton User Library for years. The issue can be replicated across all Cremona Quartet sounds.
I could send a video but apparently I'm a little too new to the group to insert links.
