Serum connecting to MIDI keyboard

I have recently downloaded the Serum demo just to try it out, but I found out that the knobs in the program are not able to link to the knobs on my keyboard. Is there a way of linking them? I am using FL studio 12. Hope you can help!

Yep, that's usually the case with most third party vst plugins. To link the knobs on you keyboard to serum knobs (or even create automation clips), you have to link the parameters in your browser:
1: Open Up Serum
2: Go to the top left corner and click on the triangle (right next to the settings knob)
3:  Select "Parameters" -> "Link all Parameters" and your FL Studio file browser will open all the sources in serum which can be linked

and then you can start right away!
