Well, by comparison, there have been very few modular performers. No? Compare the ones you mentioned (not all of whom, to my knowledge, did modular performances, did they?) to the performance history of jazz, rock, metal, western canon, etc. We’re, somewhat, treading fairly new ground here.
A good indication of this is the lack of literature.
Even more so if you base your comparison on the basis of modular being an instrument (not discussing keyboards here, I’m talking modular as the interface itself), we still fall short. Guitar, flutes, etc, etc, they all have their canon’s and their extended techniques.
In case my point was not clear, I consider this a good thing! It’s a positive attribute of modular performance which makes things easier for the performer.
