OK, tried it. Worked like a charm. I downloaded the ladspa2vst bridge from the site and compiled those to test jost. Note: replace the vst directory with a symlink to your vstsdk/source/common! The compile script then takes all the ladspas you have and makes vst .so's for them. As per the instructions, you copy jost with the name (without the .so) of the plugin. Crude but does work. A little script to do this for a directory full of .so's would be convenient (may try this if I can remember enough of my Perl). Note: jack-fst works (some of the time) for native Windows VSTs. Actually was on Debian Sid for a while (in a sort of non-Debian-standard manner). Wondered about compiling such a thing without WINE. See, it can be done. Now for ASIO? Note: Such opensource packages based on "non-free" stuff like Steinberg's SDKs go into a category "contrib" in Debian parlance (same would apply to Ubuntu).
