Hello people, I recompiled wine with the wineasio patch: here is a screenshot running Reaper with 128 frames/buffer in Jack. http://people.jacklab.net/metasymbol/pixel/april.jpg Reaper running pretty stable, sometimes the graphics are a bit slow... but no xruns :D So I think apps like FST are not needed anymore, because wine with wineasio is more stable then any other wrapper. And because wine is LGPL, no licencing problems for distribute the binaries. Thanks to Robert and Ralf. The wineasio patch: http://people.jacklab.net/edogawa/wineasio/wineasio.zip regards Michael PS this is no April joke ;)
