U-he Zebra2 doesnt scale correctly

[calimerox]

When I open Zebra2 and want to resize the gui to adapt it to my screen resolution, the following happens (see attach..) It just happens in mixbus, not when i use bitwig i.e.... any idea what that could be ? Thanks!!

Hi, I've been researching your problem, which I can confirm
in several U-he synths in Mint17. Never noticed before,
as the default screens are what I use.

I checked U-he synths in the latest qtractor, and attempting to scale
crashes qtractor by a mighty segfault.

So I switched to pclinuxos, with a 4.8.12 kernel, and a slightly
older qtractor, and the scaling worked fine.

So I tried in Mixbus, and the right-mouse-button on the Zebra2 gui
to launch the scaling dialog, did nothing.

And as you mentioned, bitwig worked OK
I'm going to post some terminal output
in the linux-zebra devs forum in a minute,
he's quite helpful. Pounds on wood...
Cheers

Yes this is the case. In Bitwig it works all right though.

When I was not using Bitwig yet (now all synths are exclusively used in Bitwig and Mixbus32C for mixing only) I simply modified the u-he configuration file to indicate a higher resolution percentage at startup. A few tries and I got the one I wanted.

Eg. for Zebra2 (same principle for all u-he plugins) :

In ~/.u-he/Zebra2/Support/com.u-he.Zebra2.Preferences.txt :

V_PROPERTY name='Preference' id='0' value='AllViewsefaultUISize:180%'

Does the issue persist after setting the scaling, save, re-load session?

Reducing the scale always works here, increasing the scale, needs a re-init of the u-he linux plugin-GUIs. (it's fine on other platforms)

Increasing/decreasing the scale works fine in Bitwig, Linux Mint 17. Bitwig does not put something around the GUI, though.

Modifyig Zebra2's cfg file equals the procedure you described, but faster. Once a new scale is set, Mixbus will show the u-he plugin as expected.

This works, thanks for the heads-up! ...but, there's more.

In qtractor, right-click the Zebra gui open the scaling dialog works,
and shows this message:

AM_ViewMan::handleMouseDown
AM_ViewMan::addUndoObject inUndoObject == 0: 0
validateUndo
currentUndoObject->__end( true ) == false
undoObject Change Parameter reports invalid!
MouseUp Without Tracking
poll failed: Interrupted system call
X11 ConfigureNotify
---------------------------------

BUT the same right-click in Mixbus does nothing,
and leaves the message data explained below:

Opening the Zebra gui, terminal output ends with
this line:

AM_VST_Editor::getrect 988 x 708

-------------------------------------
(The correct scale from the edited prefs)

Right-clicking the zebra gui to open the scaling dialog
does nothing, but gives this terminal output,
where 'test' is the name of the Mixbus session:

actually writing state to /home/me/test/test.tmp
renaming state to /home/me/test/test.pending
AM_ViewMan::handleMouseDown
AM_ViewMan::addUndoObject inUndoObject == 0: 0
validateUndo
currentUndoObject->__end( true ) == false
undoObject Change Parameter reports invalid!
MouseUp Without Tracking
failed to read menu output: Resource temporarily unavailable

qtractor output again:

AM_ViewMan::handleMouseDown
AM_ViewMan::addUndoObject inUndoObject == 0: 0
validateUndo
currentUndoObject->__end( true ) == false
undoObject Change Parameter reports invalid!
MouseUp Without Tracking
poll failed: Interrupted system call

Maybe all this reveals possible solutions?

Another thing I noticed, as Reaper presents separate lists
for VST, VSTi, VST3, VST3i, and Instruments, I found that
when Zebra2 is selected from the instruments list,
or VST3i list, the Zebra2 gui wouldn't appear, (sound worked)
but the gui loads fine when selected from the VST list.

While Discovery Pro loads from both Instruments and VST.
Plugin coding must be akin to herding cats.

You coders must have a great stress managent program...
are your offices in Colorado? Or moving there soon?

I guess you need to update the u-he plugins (rev 5332)
