A similar approach (effectively node based, generative music)
I used to play with an earlier version of Nodal, great for someone that has an ear for music but no formal training. Also, Brian Eno.
The concept looks pretty identical to Nodal, as if they used the same specification.
One interesting method I have learnt over the years is to use logistic map function to create some random notes:
It is possible to do part of that in Bitwig as well, lots of ways to have probabilistic triggering of notes and patterns that trigger others.
