Hi, Harry,
well, the newest update just came, so I have tested one actually...

What I saw, nothing is changed for me unfortunately. My test procedure was the following,
1. I have created just a simple stereo track, also stereo output bus, imported some stereo file, and insert BARK - everything works fine,
2. I have created 5.1 track, also 5.1 output bus, imported the same stereo file, and insert BARK - distortions appeared,- well, maybe because of I use stereo in 5.1,
3. Well, I moved BAR into i2 inserts slot, and placed Waves's UM226 stereo/5.1 upmixer on top to get 5.1 signal as input to BARK - sure, I saw 6 bars at IN meter, also 6 bars at OUT meter that means BARK is started to work in 5.1 - distortions STILL appeared...
Any suggestions of how I Can test this plug?
P.S. Forgot to say, REFLECT works fine in the below mentioned set-up - any distortions...
