Hello to Berlin!
Thanks you for your kind answer.
.. I will try hard to see you at Berlin Maker Faire ..
.. Yes, i have already stumbled over "Polyphone", for for some unknown reason i cannot get it running on my laptop.
For the "Fairlight" project, I'm still in the "proof of concept" phase, because i cannot make up my mind which sort of software to use, like C, some or all of the Python Libraries, PD, MAX/MSP, Super Collider, Csound (!!?), or some of the more commercial packets like "Morphine" from Fruity Loops. (Just starting now th explore the Linux world for additional candidates).
I appears to me that the open Zynthian concept will bring essential help to integrate these different possibilites into just one single "Music Software Bus" system )))
