In my opinion the best daws for making electronic music are Ableton and Fl. Personally I just use a little ableton to add some vsti to my recording.

Ableton has quite useful hardware for creating electronic music https://www.ableton.com/en/push/ .

I think your idea is to have two synchronized PCs.

1 pc for playing virtual instruments
1 pc for sequenced parts or songs.

i I think setting "push" in two or more parts:
1 to play a vsti
1 to trigger songs
It's enough.


You can also configure the computer keyboard as an instrument or midi controller and be able to share the functions between them in the same program.
As I say I just use a little ableton, but I would advise you to read the manuals of ableton and push 3 to see if they provide the solution.

If you want to use two computers and a drum machine or other hardware, this could be useful

as far as I know and I have understood, with ableton and push surely you can.
If I have not understood your question and you could explain it to me better, I would be grateful.
