Still getting difficulties to get good and reliable results. .
I'm getting really weird things .. the difficulties are to get it speak each time the same sound ..
When my code to talk to the S&S will be stable and reliable i will add the midi functions to it.
After few investigation and some Bus sniffing with my Open logic sniffer, it seems that it need to send a load address command at each address nibble. Will test that if it finally work.
