Not mine but a quite nice library of patches!

Just bought a Korg Monotron and got amazed. I'm also interested on learning how it works and what's behind it's ~space magic~ so I found this thread.

I haven't tried your patch, LaurentC, but I found this project which is based on a PD patch: https://github.com/jkandzi/Monotone-Delay

The youtube demo sounds quite nice!
