With the CC121 you can control more things. However it is more work to get it t here. Console1 is more ready to go, or does not work at all. Eg anything except softube or UAD. While CC121 works fine with waves and fabfilter (and uad and softube) For cubase 9.5 there was commercials about “fully integrated” support. That has not happen. Both are great, but steinberg does not let them shine, with better software they could be pro grade stuff.
