This lot are doing some interesting work:

My own view is that groove/swing or whatever you want to call it - it being divergence from a mechanistic performance of a score - is not predictable but is capable of emulation to the degree that most listeners won't differentiate. I used to spend a long time trying to achieve a playing feel in MIDI sequencing, using timing, volume, and attack to create patterns around the beat. It was somewhat successful.

The ideas that interest me:

A score is a diagram - or an incomplete set of instructions - it does not play itself and what's not there is more important than what is.

An idea often happens in an abstract way, like a Platonic score, perhaps.

In music a beat is not the equivalent of a mathematical point on a mathematical line. It has its own dimensions. No two beats are exactly alike.

Cheerio
