Hi Fons,

The "developers of jack2" (…) don't have time right now to invest for this resampling code rewrite, but will be very interested to zita-ajbridge working. Concerning direct ASIO backend support, attached is some files I started to write some months ago, taking the LinuxSampler code base as a starting point. But the code is absolutely not ready as has even not been compiled….

Would "the research center of a very big, corporation" be ready to put some money to have theses development be accelerated ? 

(in any case,  I can at least compile any new code base on the Windows development machine we have, and publish new Windows binaries, and probably do the same on OSX).
