It's good to see another positive thread.
I agree, the ProChannel is great. All of the modules get used here, with always something on every track. The CA-2A is particularly nice, but I like them all, even the 4K Channel Compressor, which took me a while to get into, but now use a lot.
I guess they are modelled well, and the workflow makes it so easy to set up a channel and get the right sound. Switching modules in and out, being able to see them all together so easily without cluttering up the screen with VST GUIs, intuitive controls, just make dialling in great tones a gas.
I don't know if it's my advancing years, but I find the GUIs so easy to use, I guess because they are modelled on analogue units - they just seem so familiar and comfortable for me to use.
