Patch for cl-osc pushed as acbdaec070f39b723a1b964ffa7fbd4b640bbd8e. Concerning the patch for cl-collider, the 'patch-executables' phase replaces "jack-connect" with "scsynth": --8<---------------cut here---------------start------------->8--- (add-after 'unpack 'patch-executables (lambda* (#:key inputs #:allow-other-keys) (substitute* "server.lisp" (("which scsynth") (search-input-file inputs "/bin/scsynth")) (("jack_connect") (search-input-file inputs "/bin/scsynth"))))) --8<---------------cut here---------------end--------------->8--- Is it really supposed to be like that? Also, in "server.lisp", doesn't the path for plugins (*sc-plugin-paths* variable) need to be patched too?
