i came here by searching for Patches for Paul Nascas ZynAddSubFX, the Page looks quite promising...
The thing i found quite strange is, that you seem to ignore LINUX completely. I know, there is no completely stable Host for VST in LINUX yet, but there are lots of people out there, that manage to load at least VST-FX by using wine-vst-server and by the way: there are LADSPA and JACK, both developing at an enormous pace.
I have experimented with Steinbergstuff and Samplitude for years and switched to LINUX 3 years ago, within 2003 the Stuff started cooking and today i do not shed a single tear for abandoning all that "Standard"-Apps.
I Got Zynadd, AMS, Rosegarden, LADSPA, JACK, ARDOUR Rezound and dozens of other cool Progs to build my tracks. All free and legaly and methinks, this could be of some Interest for you People here also.
p.s.: i would be pleased to help, if someone here should need a hand to get Soundprogs working with LINUX
