Automated lines

Hi All

I wanted to ask is it possible in Ableton Live,
To control your automation lines and breakpoints using a control surface.
I am using an Vestax VCM600
So i have mapped my Low Freq Rotary knob to EQ Three audio effects Low freq.
So i turn the knob on the control surface and i can see the knob turns on the screen.
If i am editing a track or making a mix, instead of using my mouse and clicking and
moving lines, can you do it with the turn of the knob?
In the picture i have started drawing an automated line with a breakpoint but when i
try continuing using the the Low freq knob it greys out the line.
Is this possible or do i just need to adjust some more settings?

thanks

On your first screenshot there's an arrow button at the top lit orange. That turns on whenever you have something automated and you manually adjust it (eg: turning the knob). Hitting that button will re-enable pre-made automations. You can hit the arrangement record button to capture your knob movements rather than having to draw them by hand.

thank you for your response
I appreciate your help
I must be a big twit
I read the exact same thing on Ableton 10 Live Power
before posting my question,
So it must be something i am doing wrong or my setup ?
When i drag a track into Ableton do i drag it into MIDI or Audio ?
Everytime i try i keep getting the same result
the automated line breaks and i get that orange arrow button
Now there is a few record buttons do all 3 need to be on ?
I have tried and tried again without success
