New AWC608 DSP OS for 'um' require over 30

[Tech_Marco]

I've request a special OS for folks who's machine require "um" over 30. The current OS support 2 to 30 only and it is very stable. But for some machine, over 30 may be necessary. The OS is ready. Let me know if anyone need it. For other folks, there is not much new change.

By the way, the precision over 30 is not as good as within. So, use it with caution
