> how i can sync one music from ableton with doepfer with dark link i can

do that

The MSY2 can be used to convert Midi clock into analog clock signals. We are
working on a modular version of the MSY2 with some additional features (USB
interface, several outputs with different clock dividing factors and
polarity and some more). But there is no release date or price available so
far.
