I can see your point and it's a valid one. Clearly in the example you give above, the main creative process would be in the preparation, composing and sequencing, rather than the performance.redziller wrote:If the artist believes they can produce their best work exploring more parameters than can be manipulated in real time then they may well chose to discard improvisation as a technique.
It's important to remember that it doesn't have to be a choice just between improvisation or pre-programming. Most Western music is composed and played manually, sometimes allowing space for improvisation (e.g. guitar solo). A good illustration of this style from TD is the 1977 North American Tour.
