thanks for the already very nice Pro-Q3 upgrade. Nevertheless I believe there are some features missing to be ahead of the game again. Besides the frequently requested sidechain- and compressor controls a multitrack-feature would be really great.
At the moment it is very easy to detect problems in the External-Spectrum view, but if you want to change another channel, it involves many clicks to find and open the other Pro-Q3 instance in the DAW. That is not streamlined and feels half way there.
I would suggest that it should be possible to select not only the active External Spectrum, but also the active instance for edits within each GUI.
There is a very similar function in Meldonye studio too, which I daily use:
Thanks for your attention! :)
