Doepfer

Hi to everyone of the group,
I will very soon buy a Doepfer A100 system II.
I am looking for good books about modular synthsis, in english and french.
I have been on the Doepfer site and select some of those who are suggested, but I would like to know if you have more suggestions ?
Is there any translation of the book by Keld N. Sørensen: Modular synthesizers ?
And also of : Enrico Cosimi: Analog & Virtual Analog / Come funziona un sintetizzatore, supplemento alla rivista Chitarre ?
Do you know other books written in french and/or english using Doepfer examples as these ones ?
Thank you for your kind advise,
Friendly regards,
Marc-Henri Arfeux
