[SOLVED] Ardour and Drumkv1 - failed to instantiate LV2 GUI
When I add Drumkv1 to an Ardour midi channel I can't launch the gui via double klick. Too bad, I created some nice bongo samples and now I can't play with them
Ok, I've seen some posts with this issue e. g. here https://community.ardour.org/node/13450
but they seem either outdated or don't point to solutions.
Any suggestions how to go about this? Or what logs to post for support?
some details:
The build configuration reads: "LV2 UI embedding: True"
The Ardour log window reads: "failed to instantiate LV2 GUI"
Ardour 5.8.0 "Music for Airplay" (rev 5. Intel 64-bit
qmake --version reads: QMake version 2.01a Using Qt version 4.8.7 in /usr/lib/x86_64-linux-gnu
ubuntu 16.10 / Intel® Core™ i3 CPU 540 @ 3.07GHz × 4 / 64-bit

Are you using kxstudio repo? I saw something that sounds like this in a recent update there - viewtopic.php?f=47&t=17028#p81209

Re: Ardour and Drumkv1 - failed to instantiate LV2 GUI
Yes, big PITA.
For now a work around would be either fabla or the lsp sampler.
The v1 suite of plugins are really good tools though

Ok, so it's very likely a QT framework issue ... no, installed from source drumkv1-0.8.2.tar.gzsysrqer wrote:Are you using kxstudio repo?

Re: Ardour and Drumkv1 - failed to instantiate LV2 GUI
it seems the latest ardour5.8+git is a dang PITA when dealing with LV2 plugins Qt5 UIs, being all of the vee-ones one fine examplesysrqer wrote:Are you using kxstudio repo? I saw something that sounds like this in a recent update there - viewtopic.php?f=47&t=17028#p81209
well, just a different day, same sh*t all over again
byee
ps. you can try to build drumkv1 (and the othe other v1s) from source again, but now with ./configure --enable-qt4 ... hope it works. but then it is plain outrageous why ardour5 is shipping with unbelievable broken code to start with.

Re: Ardour and Drumkv1 - failed to instantiate LV2 GUI
and why the fsck have you to fix it on the v1 lv2ui .ttl side at all? ain't that enough evidence that ardour's is gone fubar?falkTX wrote:The code is not broken, that's not the problem. I tested that qt5 embed thing and it works fine.
There's one problem that ardour official gcc5 builds use debian stretch, which contain a newer version than some other gcc5 systems include - like Ubuntu 16.04.
@BerlinBayBand: just run this:which disables the qt5 ui, leaving the external.Code: Select all
sudo sed -i "s/drumkv1_lv2:ui, drumkv1_lv2:ui_external/drumkv1_lv2:ui_external/" /usr/lib/lv2/drumkv1.lv2/drumkv1.ttl
should make it work once again.
nm. i'm outta here :/

Re: Ardour and Drumkv1 - failed to instantiate LV2 GUI
Well - aside from code astheics - it worked. The Drumkv1 is nice, spent two hours hacking around the bongo samples.
Can I mark the thread as [SOLVED] simply by changing the name?
Thanks falk, thanks guys!
make sure that your LV2 plugin path actually is /usr/lib/lv2
They might just be stored in /usr/local/lib/lv2

Re: [SOLVED] Ardour and Drumkv1 - failed to instantiate LV2 GUI
I have yet to attempt this fix fro Ardour 5.8.0 on 14.04, but will test it out tomorrow. I have a simular issue with the newest Calf-audio-gear plugins. Is it possible this fix would also work for them and will I have to apply it on a per-plugin basis?

That seems rather bad. How does one package type affect another?

Thanks for that. Makes sense now.
