Thanks Yann, it really means a lot :) I started learning some python three years ago, but motivation was low without an actual project. With the need for such a tool at the quarantine sessions came motivation and I got hooked :)
The more I dive into faust, the more fun it is! (Meaning: You will probably have me around soon with more newbie questions :D) Merci and take care, Klaus On 29.07.21 14:14, Yann Orlarey wrote: > Hi Klaus, > > Congrats, I don't know your programming background before starting > this project, but I think it is a remarkable achievement! > > Yann > > Le jeu. 29 juil. 2021 à 11:11, Klaus Scheuermann <kla...@posteo.de > <mailto:kla...@posteo.de>> a écrit : > > Dear Yann, > > so here is a quick update.
