Yes, it works for all this.
In term of smoothness with cc74, I guess it is, but I didn’t dig to know if it was super smooth though.
You need to know it only works using note per channel DAW. It doesn’t in Bitwig for instance (but that’s maybe another subject).
I was in the same situation you are. Thought about selling my halion 5 version but I finally did the upgrade because it works well in multichannel mode with my Roli Lightpad.
But to be cautious, just try demoing it and try by yourself. If your demo is expired, ask for another, this is what I did. I wrote to licensing support on my using my account.
