ZynAddSubFX, 2 possible bugs ?

[mikobuntu]

Hi I am currently using LMMS master branch right up to date as of today. Im running on ubuntu 12.04 32bit. I have noticed any sliders in the actual Zasf GUI will get pixelated/trapped whenever moved. And also i see a lag in loading time where zasf used to load within milliseconds... can anyone else confim ?

• note cpu hits 100% and LMMS gui freezes until zasf is loaded fully*
  

see where my mouse pointer is hovering...

thanks Mikobuntu

64 bit Ubuntu 12.04, and I can confirm that slider problem in master. And the "Instrument Edit" window seems to get its background from some random window in the system, see upper right-hand corner of screenshot above. I had some xterm text in it...

Neither of these happen in a stand-alone Zynaddsubfx compiled from its master branch.

Marking this for 1.1 as it's something that should be solved before release.

I got the visual artifacts to go away by reverting this line to that of the old Zyn code.

BEFORE

xywh {247 621 395 360} type Double box NO_BOX visible

AFTER

xywh {182 214 395 360} type Double hide

Not entirely sure how or why. Instinct is a problem with the constructor that the hide function fixes, but this seems like it would be a problem upstream too.

Possibly unrelated but the behavior is now the same as #703 (Apple) where audio works fine but the GUI won't load at all.

Zasf GUI will get pixelated/trapped whenever moved

• @diizy 's pull request Sync with Zyn repository - includes a GUI fix, also a fix to RemoteZynAd... #916 should fix Zasf GUI will get pixelated/trapped whenever moved (thanks for the commit Vesa). Please confirm @mikobuntu or @softrabbit or anyone else (you will have to use Vesa's stable-1.1 branch until the pull request is accepted)

Zasf GUI slider artifacts

• Haven't figured out how to fix the Zasf GUI slider artifacts yet. I'll look into the sliders and see if we can provide another small patch for that. Update: http://www.kvraudio.com/forum/viewtopic.php?f=47&t=415142

Zasf lag in load time

• In regards to Zasf lag in load time, I don't have a native Linux install to test performance out on so hopefully someone else can confirm that report.

A side note, these should probably be three two separate bug reports but I'll do my best to track them all here.

Another side note... to follow up with my previous comment on the possible relation of these issues to the Win32 crashes, the bugs are not related but FYI - Win32 has been fixed with pull request #919.

I can now confirm that i no longer have the lag in ZASF loading time, it could possibly been due to building in a non clean environment or such, but after doing a new/clean install i no longer have the problem, so this part can be closed... and indeed i should have done these as separate bugs ooops :0

thanks Mikobuntu ;)

Ok, I have some more information on the GUI artifacts. It appears to be new(er) behavior of FLTK and I created by "NO BOX" and I was able to find some information on the mailing list about this.

Instead of linking the original article, I'm linking the post to the KVR dev team which may be able to fix this upstream.

Got it.

cd ~/lmms/plugins/zynaddsubfx/zynaddsubfx/src/UI
sed -i 's/NO_BOX/FLAT_BOX/g' *.fl

Will submit pull request for now and request these changes are pushed upstream.

Remember, the pull request should be filed in the lmms/zynadsubbfx repo

Tres, maybe you should revert the coordinates too? I'm sure they were
changed for a reason...

[tresf]

revert the coordinates

Yes, that was my intention but I missed it thank you. Committed. LMMS/zynaddsubfx#2

Here are the updated Windows installers which address the #892 "show voice parameters" Zyn crash on Windows XP as well as the #759 "visual artifacts" bugs.

I intentionally and prematurely bumped the version of these installers to 1.0.92 as to easily distinguish from the previous versions.

64-bit

These should be fixed in latest stable-1.1 now so I'm closing this issue for now.
