Thanks! I think I pushed it too much for a moment when I added 16 aux buses (32 AMS 2 ch mixer plugins!). The Zynthian froze every time I tried to remove any plugin or layer, and also when trying to switch to a less complex snapshot. And as it was my default patch, I had to delete it via the browser to be able to use the Zynthian again. This is the snapshot I had working earlier, with 14 auxiliries: 014-JV;Gain.zss (52.8 KB)
