Hi everyone I'd really like to be able to finally use the new and shiny ZynAddSubFX in Qtractor (latest from source). I tried the "zynaddsubfx_dssi" but even ghostess could not start it: ⚡ ghostess /usr/lib/dssi/libzynaddsubfx_dssi.so ghostess: ghostess starting... ghostess: failed to load plugin library /usr/lib/dssi/libzynaddsubfx_dssi.so Then I build the full monty using the latest source tar.gz on SF <https://sourceforge.net/projects/zynaddsubfx/files/latest/download?source=files>, because I could not get the git master branch <https://sourceforge.net/p/zynaddsubfx/code/ci/master/tree/> to compile (I'm using Ubuntu 14.04 with 3.13.0-36-generic). Now ghostess does load something ⚡ ghostess ~/src/zynaddsubfx-2.4.4/build/src/libzynaddsubfx_dssi.so ghostess: ghostess starting... ghostess: instance 0 on channel 0, plugin 0 is 'libzynaddsubfx_dssi/ZASF/inst00' ghostess: listening using ALSA MIDI ghostess ready I get a small window with just a "UI" button ; when clicked, it reveals a window with a "Send test note" that works! :) Just a sine wave "a" but still. There are "bank" & "program" menus, but they don't seem to work. In Qtractor, I get basically the same thing, without the test sound :/ It seems to be lacking both UI definitions and instruments. I also tried building Carla and puttin bin/carla.lv2 in my lv2 dir, carla showed up in qtractor LV2 tab but failed to load with suil error: Unable to wrap UI type <http://kxstudio.sf.net/ns/lv2ext/external-ui#Widget> as type <http://lv2plug.in/ns/extensions/ui#Qt4UI> exec failed: No such file or directory read() returned 0 force killing misbehaved child 11048 (start) Carla assertion failure: "fPipeSend != -1" in file ../../utils/CarlaPipeUtils.hpp, line 422 Carla assertion failure: "fUiServer.isOk()" in file CarlaEngineNative.cpp, line 935 QVariantMap DBusMenuExporterDBus::getProperties(int, const QStringList&) const: Condition failed: action (...) How can I link all this together? Wow, I'm on it since early this morning!? Thanks to anyone who's listening. Phil PS - I tried the "zynadd" package (can't find the sources/repo) w/o any luck PPS - WAIT! I missed the " ZynAddSubFX" entry in the LV2 list! This is from Carla (I tested it by trying to remove the carla.lv2 dir) ; It does load (and a song save / qtractor restart yeld no error) only I can't neither load a new instrument (I cloned the instrument repo <https://sourceforge.net/p/zynaddsubfx/instruments/ci/master/tree/> and selected the dir as the default) nor seem to affect the sine sound playing (I turn the knobs, say ADSR in *edit instrument* and nothing changes)) so now I don't have ZASF but can see it from where I am :) Thank you for your patience.
