Yeah I think there's a lot of room for experimentation in this area like locking the grid to musical modes (mixylodian, phyrgian), setting up intervals, etc.
Myy experiment kinda supports every mode. For example, you can pick C major scale and it will have exactly the same notes as G Mixolydian or you can pick E Phrygian.
Although, due to the chaotic nature of the simulation and also because the algorithm to pick notes that I chose, there is no tonal center, so strictly speaking we can't determine mode.
yeah. One thing I've done in the past with experiments playing around with genetic algorithm derived music is that I would setup a recurrent tonic that would play every X beats to musically anchor to a signature and/or mode.
