Hi

> Thanks for your advice, this solution seem a good startup for this price, de facto is a Dark Energy.

I also would recommend an A111-5. You should consider also that you need
a housing with powersupply; and this will be the most expensive part at
the beginning. The cheapest in the Doepfer range is the A-100LC6 with
240 Euros - except you go the DIY way: A-100DIY1 for 120 Euros. But
accounting the time and effort to build the real case, the A-100LC6
would be cheaper.
