That’s more of a question for @Ess as which algos a synth provides are the choice of the designer. I would imagine the considerations were:
- can it be parameter locked to another algo and have it still produce sound?
- is it different enough from the other algos to justify?
- is it versatile within itself to create a variety of sounds?
edit: I found what @ess had to say on the topic
I too would like to know if there is a style of patch that was anticipated for the algorithms. Some of them are pretty unique (algo 6) and wonder if they are inventions or inspired by some synthI never heard of.
