With Halion try right clicking the QC Knob you want an automation lane for (either in the Rack or from inside Halion itself). When the menu pops up click on the option to show the Automation lane. That should cause a lane to pop up in your Track List, and it’ll be under the Halion VST outputs (as opposed to being grouped with the MIDI track) if you’re using Halion in ‘Rack Mode’.
At that point you should be able to toggle W and R buttons for the lane as needed.
Halion is a little different when it comes to assigning QC parameters and such. It can get pretty deep because each ‘layer’ inside a ‘program’ can have independent QC’s laid out inside. Sometimes you have to dig around a bit to set up exactly which things you want to remote control and/or automate. So…it might be necessary to do a little program manipulation to get the kind of QC behavior and automation lanes you want.
Alternatively, you can just control stuff with MIDI CC events instead. Make sure the Halion Track is armed for recording or monitoring and right click the control you want to automate, choose ‘learn’ and move a slider or knob. This is more of an old school MIDI method. Personally, I like this method and use it often…
At that point you should be able to manipulate the control via remote and record it into the MIDI part. You can also elect to keep it in an automation lane of a MIDI track instead of it being embedded in the MIDI part.
