Dear support, First of all, thanks for enabling a Linux version of your guitar effects software. That, and the sound it has were the reasons that made me purchase it. The linux version of the plugin however crashes when certain presets are loaded. A preset that crashes is for instance the "02D Comfortably Torpid". Carla can handle the problem in the "carla-git" version (namely it works), but not the default released version (luckily the plugin crashes but carla survives). At crash time it logs: Code: Carla assertion failure: "unlocked" in file ../utils/CarlaSemUtils.hpp, line 182 waitForClient(process) timed out Ardour6 crashes along with the plugin saying in the command line: Code: Emulate VST Bypass Port for ToneLib-GFX dispatch_x_events: ConfigureNotify cfg: (1200 656) plugin: (1200 656) The Tonelib GFX application works fine without problems on those presets. Please let me know if I can help dig out this problem with more information/logs.
