(currently manually translated from ScalaCollider which has slightly different syntax and argument names)

This was done with Mellite’s object ‘Negatum’ and newly integrated automatic parametrisation method.

Wow! The sound is fantastic. Thank you for sharing.

I would love to hear more! And learn more about your work on this genetic programming algorithm.

Thanks. There is an older introduction video here: Mellite - Tutorial - Part 11: Negatum genetic programming of synthetic sounds - Diode Zone

And for the new parametrisation, I created a new video: Mellite - Tutorial - Part 18: Automatic parametrisation of Negatum generated sound programs - Diode Zone
(see description below video for link of example workspace)

Super cool. Thanks for sharing the videos!

I’m looking forward to getting in front of my computer and testing out your code blocks.

What was the target sound was for your first example, and how many iterations did you run to get this result? Really love the sound.

7

The target sound is the one briefly shown in the beginning of the second video, and it’s not that many iterations, I don’t remember from which iteration the example is, somewhere between 12 and 25; that’s because I use a very high population size (10K) and so it takes very long for each iteration even on a fast computer. It was run with the limited set of UGens described in the video, rather than using a broad set.
