in order to make WL even more flexible I miss two major points / functions:
For those mastering engineers prefering the hybrid workflow (mastering in the box with inserted outboard gear) WL is limited when the requirement is given to use 2 inserts (e.g. one for analog gear and the second for digital outboard gear, e.g. TC System 6000). This is the point to look for another DAW. Why don´t you offer at least a second insert option so that this combination of 1 analog and 1 digital insert would be available?
When we started with digital mastering a bit more than 2 decades ago we used to work with two tracks: One for the source material without processing which would be fed to the analog chain and the second lane to re-record the processing. This is kind of old school but with this option WL would cover almost all available workflow approaches in mastering (except the ability using automation within a mastering project).
You would increase the target group of WL8 with ease. Why don´t you do that?
