#20 qmidiarp LV2 plugin not working well in qtractor

I'm using qmidiarp as a LV2 plugin in Qtractor and it all works fine when composing and arranging, but when I try to export the song to a wave file with Track/Export Tracks/Audio I can hear the other tracks, but nothing from the tracks using qmidiarp. qmidiarp is built from git trunk about one week ago (using --enable-qt5) and qtractor is version 0.8.1 from kxstudio on Ubuntu 17.04. According to RNC/Qtractor the plugin doesn't seem to play well on export rendering (jack freewheel mode, faster than real-time): http://www.rncbc.org/drupal/node/1823

Hi there, thanks for your report. I will look into it and probably be in contact with Rui. Hold on for some days though

Just curious if there's any progress on this.

Absolutely love QMidiArp- I really like "programming" the arpeggiator- simple but versatile.

Thanks Wayne,
I posted something there. The info about everything going mostly right when host transport is not active is interesting.
Sorry for the utter slowness here at the moment....

  Fantastic just to see you get some time to have look at this- I'm really greatful.
  
  I've been working with QMidiArp pretty extensively for at least 4 years now, glad to know there's someone keeping an eye on it.
  
  I recently did a blog post (the start of a series I'm planning in order to share my workflow) with a bunch of my arpeggiator patterns for QMA-

  These are just the tip of the iceburg- been in deep exploration mode, so they're kind of all over the place- shows the potential though.

Hi Wayne,
Rui has just committed a change to qtractor so that transport start information is sent to plugins also during track export. Could you try this out see if it works for you?
I would also be interested in qmidiarp lv2 crashes that seem to be reported at rncbc forum. If you can point me to something systematic don't hesitate to open a new bug.
Nice experiments you did with patterns, thanks for sharing!
Cheers

  Thanks Frank- I just responded over there- definitely some progress- yay! I do my happy dance! :-D
  
  I haven't actually had any crashes yet. Will report when I do though.
