How to trigger a track instrument

Hello! I hope this is the right Place for this topic.
Problem:

I have serum synth and chtulhu arp innstalled.
I want to to trigger chtulu from serum, so that the serum sound i playing.

Since the chtulu is an instrument and not an “insert” it has to be on a seperate track.
So it is possible to trigger it With the serum track ?

best regards

Did you get an answer? Basically - I think I understand your question - you can record the serum synth in a midi track and then you want the chtulu to play those midi notes?
