If the multiband (individual band) hold control is to be removed, please reconsider. I use this control because I don't want to change gain unless it is necessary or desirable. I purchased Stereo Tool precisely because I want a large number of user adjustments and maximum flexibility to implement processing structures. If the product is simplified I will not be particularly motivated to purchase more licenses.
Please leave every control in the product and consider adding more. You can simplify it by having layers of access in the GUI just as the Orban and Telos Alliance products do.
As you suggested I will eventually suggest control descriptions from my point of view.
btw- could you please clarify the location of Bandpass section in the signal flow. Presumably low-pass filtering for the AM and FM outputs is in the output section. Therefore, Bandpass would probably be after the Repair section, but before the Auto-EQ section. Is the low-pass of Bandpass actually adjustable? You can appreciate that some users might want to remove frequencies that will not be transmitted before Auto-EQ or Multibands can act on them.
Also, this a really big ask

but for users with multichannel sound cards, could you consider a comprehensive monitor section?
When a processor is on the air, it helpful to have a monitoring output that can be easily switched between input, output and a bridging tap of every significant point in the processing path. That way the user can hear what (for example) what the output of a mid-band in the compressor sounds like, or exactly where some pumping or objectional artifact is coming from. Most of the time these things are noticed on-air, and if the user is physically next to the PC, they could easily zero in on why a particular song is not working with the processor, by comparing input, output and bridge-tapping sections.
Thank you !
