Would it be easier to use synths?

 So there is a genre of music that is auto-generative, in which synths are placed in order to send signals that eventually become music, some of the signals that are sent receive different versions of parameters to change, randomize and improve music generation, and in the process of a patch it seems like it should be possible to introduce the changes in parameters through different signals, If I'm able to find a way to emulate ambient generation through synthesizers, it in theory should be easier than procedurally make the music myself.

I wanna make sure that I have pattern generators that can be edited first but it appears like vsts that are able to generate random Midi notes like this one if so it would be cool to make a version of the program that generates parameters and then see if I can generate communication between the program and reaper. Which so far only seems to be possible through a note on/note off message.
