QTractor and Wine and 64bit (liblo issue)

Hi there,

the first time in my life I use a 64bit computer, initially I felt exuberantly happy ;-)

QTractor insists on using liblo7 (and liblo-dev for compiling), whereas Wine for VST usage insists on using liblo:i386 and removing liblo7.
I am using Delay Lama VST PlugIn with its fine portamento feature to adumbrate vocal parts and an Korg X50 editor VST plugin both I would like to use continuing. Do you please have any hints to solve this problem?

With my regards,

lucky you. i wonder how you get dssi-vst to work painlessly on a 64bit linux system. nm :)

i remember having some ok-corral experience with dssi-vst a few years ago under my distro of choice (opensuse) on 64bit,

i guess lacking some wine-32bit official stuff was just beyond my call

that said, i'm afraid i cannot help you much in there

however if it's a liblo issue you should ask your distro packagers in the first place, wouldn't you?

Dear Rui,

QTractor of course has and always will have priority ;-) over vst, so I never installed dssi-vst on my new pc until now.
QTractor says, Festige VST Headers installed - so I'll install it and learn to use it.

I don't want to bother you too much, because Delay Lama vst can be replaced with a voice sf2 and I can edit my synth by pushing buttons, I only have to change into the other hall doing so.

maybe there's some (usual) confusion between VST flavors:

  • native linuxVST - these are VST plugins compiled and run as pure linux code (.so); those are the ones for which the VeSTige headers are for (do not confuse this with Festige which is a standalone host for the other VST flavor that follows:).
  • windowsVST - these are plain windows plugins (.dll) that are run under wine on linux and provided by courtesy of DSSI-VST; in qtractor they appear as DSSI plugins, not under VST type, which is for the above (native linuxVST).

Thank you for your answer, yes someone easily could get confused with this stuff.

I downloaded Festige from FalkTX's ppa, which itself launches fine, but I think I additionally have to download the sdk steinberg development kit to get the dlls working - too much alien stuff for me and my system. Sometimes I really get the feeling spending much too much time on administrating the system rather than making music!
An austrian (!) fellow, Hermann Seib, is the author of a vst host which works very well with actual wine, it's called "VSTHost" ;-)
Here is the link "" if someone is interested.

Greetings, Michael
