Surge fails in qtractor linux #545

Closed davephillips closed 5 years ago

davephillips commented 5 years ago

Fedora 23 Linux GCC 5.3.1

Greetings ! Just a quick report on the deployment of Surge on my system. I build the synth from the latest git codebase and can test it in a variety of DAWs. What I've got so far:

QTractor (latest) - Surge is found by the program but QTractor crashes when it tries to load the plugin. Ardour6 (beta) - Plugin not found. Carla (latest) - Plugin loads but sound is nothing but clicks and pops. VCV Rack (v0.6.2c) - Plugin loads via Host module and works perfectly there.

Please note that I build all these programs from source, so they're probably not the versions that most users have. Other users on the Linux Musicians forum have reported success with Carla but I think they're using the version in falkTx's repos.

Anyway, vast thanks to all the developers involved in this project, keep up the fine work !

Thanks Dave! We had another report of QTractor so something is definitely up there. And I didn't know Rack even had a VST host yet! How cool? (I have a small set of rack plugins I wrote 6 months ago).

This is very useful.

Did any of them give any odd looking error messages or stack traces?

And appreciate the thanks!

@baconpaul I suspected you were the same fellow who did the plugins ! :) The Rack VST Host module is a commercial offering from Andrew Belt, it works very well with most of the plugins I've tried, including the u-he synths.

QTractor kicks out quite a nice stack trace, I've posted it at https://pastebin.com/rdrwiWv4.

I also used the Bitwig plugin host to test it, got the same results as other users have reported:

$ /opt/bitwig-studio/bin/BitwigPluginHost64 test ~/.vst/Surge.so

So no new news there, I guess, but at least it verifies what others have found.

Just FYI: We fixed bitwig yesterday as well as a variety of other problems.

Hey @tank-trax if you get a chance in the next week or two, can you check a couple of these hosts with 1.6.1.1 and see if we are any closer? I think QTractor still blows out; and I run Carla regularly (from the repo); but taking a look at Ardour would be great if you can.

tank-trax commented 5 years ago

Qtractor still explodes when loaded. Ardour's stable release is 5. Ardour 6 is still in development. I tested Surge in Ardour 6 and it loads without issue. The only host that it has problems with in Linux as far as I know is Qtractor. All others work perfectly.

To my understanding the issues in this ticket (apart from Qtractor) have been resolved many builds ago.

baconpaul commented 5 years ago

Thanks! I will rename to qtractor fails then

tank-trax commented 5 years ago

there is an issue with the new SCL feature and Waveform 10 when Zenity is called it is below the app so in order to access it must use the Move function, it's impossible to move or Minimize Waveform as Zenity owns the screen even though it is not the top element

wf10 zenity scl

also Surge will freeze Waveform if one of the patches that can't load is selected -> related to https://github.com/surge-synthesizer/surge/issues/924

baconpaul commented 5 years ago

I wish linux was a desktop OS. Sigh.

Well thanks for the report! I know the problem with #924 but no idea what's here. Maybe zenity has an --ontop option or something. I'll look.

baconpaul commented 5 years ago

https://askubuntu.com/questions/197099/zenity-window-on-top look at that insane answer.

tank-trax commented 5 years ago

I almost posted a sigh earlier

tank-trax commented 5 years ago

it doesn't happen in Carla, Renoise or Reaper, so far only in Waveform I've seen this behaviour before with Waveform and another VST possibly because Waveform is built using JUCE and draws things 'uniquely'

tank-trax commented 5 years ago

also, Zenity is not working in Ardour or Mixbus (which is based on Ardour)

baconpaul commented 5 years ago

@tank-trax hey I think JP’s fix where he increased the buffers fixes this issue; can you if you have a moment check a recent surge in qtractor and if it works close this issue for us? Zero rush of course!

Thanks!

tank-trax commented 5 years ago

The Zenity menus work in Ardour now. however the same issue with Waveform and Zenity layers persists, but will close this issue as Surge VST2 in qtractor loads fine.

Thanks!
