Karl is an anagram of lark and this is a bird generator.
This Pure Data patch is good for art exhibitions, to sample Kraftwerk or generally electronica type of sounds from, as well as bridge pauses in your live set.
You might as well see this as an ongoing composition in early 50s electronic music tradition.
But it turns into R2D2 eventually, when you start using the built in ring modulator.
I am using this for contemporary dance pieces.
