Master branch:
- Open ROLI NOISE Drums AU in PluginHost
- Connect MIDI input and audio output - NOISE Drums works fine.
- Open plugin GUI and go to performance section (where there is a 4x4 button UI)
- Press a button - CRASH.
- Strange observation: once it crash, somehow PluginHost plays a direct input-to-output-audio, even though no input audio it connected.
