Copying synth track does not copy pan and volume of track

[StaffanMelin]

I select a synth track, right click and select duplicate track. I check the bottom three checkboxes (see attachment).

But the pan and volume of the duplicated track are not copies, only the default values.

MusE 4.0 (compiled from master a week ago)

Should be fixed in git master now. Thanks for spotting that, been there a long time. Re-open if any trouble.

Works great, thanks Tim! :)

I noticed that plugins are copied, but not their settings. Is this possible to add, @terminator356 ?

[terminator356]

It is supposed to. I stepped through the code and found the problem.
It is attempting to copy the existing synth track's controller values to the new synth track copy
before the new copy's synth section is instantiated, so there's nothing to copy the values to,
and the new copy ends up with default values, after it has been created.
Thanks for spotting, again. I think I have a fix, must try...

[StaffanMelin]

Thank you for looking into this Tim, I am sure the solution will benefit many!

[terminator356]

Should be fixed in git master now.
Tested the various copy dialog options OK with synth tracks and other audio tracks having effect rack plugins
and having static controller values and controller graphs.

Final note:
Special: Copying MESS synth tracks is a slightly different experience.
Their controllers are midi controllers, not audio controllers like the other synths.
That midi controller data is contained in midi parts, and therefore in this case copying is operated by the
track copy dialog's parts options.

Hmmm I get a "segmentation fault" when I did the following with the new version:

1. Created empty new project
2. Created a synth track with Surge softsynth
3. Opened Surge and changed to anyother preset
4. Right clicked on the synth track and selected "Duplicate track".
5. Crash

If I only do steps 1, 2, 4 (skip step 3) it works (but is kind of pointless :) )!

Can you tell me which version of surge? I am having difficulty figuring out what to download.
Did you build it yourself? VST2 or LV2 version?

Does it happen with other synth plugins?

[StaffanMelin]

It is Surge LV2 version 1.7, downloaded från kx.studio as a deb.

I also tried with Helm LV2, it doesn't crash.
