My first observation: in a scrolling user interface like this one, none of the knobs and faders should ever react to scroll wheel. Right now, as I'm scrolling the rack up and down, if I accidentally move the mouse over input/output trim faders, I could accidentally push them to +24dB/-24dB, which would result in a disaster.

Congratulations on the release, looking forward to testing it out. One "competitor" I would definitely recommend everyone to checkout is Airwindows library of open source audio effects consolidated into a single plug-in here: https://github.com/baconpaul/airwin2rack
