The VST plugin has been successfully tested on Ubuntu 16.04 with several DAWs: Ardour (5.12), Bitwig Studio (2.3), Qtractor (0.8.4). However it might behave poorly if the host does not use an audio buffer with a fixed size (i.e. Renoise 3.1.0, Radium, 5.4.9). In Carla (2.0-beta6), "Fixed-size buffer" has to be enabled in the plugin's options.
