STL Emissary Amp won't show UI anymore

Post by Toejam76 »

[SOLVED]

It worked before and now it doesn't. Carla can load the plugin and it is usuable and the presets work, but
if I open the UI, a black window shows up for a second and closes. Carla disables the plugin then.

Some output from Carla

win32:
wine: Unhandled page fault on read access to 00000160 at address 7C46D5B3 (thread 0024), starting debugger...
winedbg: Internal crash at 0x7bc5711c

win64:
Carla assertion failure: "childPID == 0" in file threads/ChildProcess.cpp, line 154, value 11238

and in the Windows version of Reaper:
err: Failed to create surface
wine: Unhandled page fault on read access to 0000000000000000 at address 000000000A205D93 (thread 00bc), starting debugger...
Unhandled exception: page fault on read access to 0x00000000 in 64-bit code (0x000000000a205d93).

I had a minor problem with it before, not showing the fonts which was fixed by installing the ms core fonts.
The issue seems to be the UI not the plugin itself.
Using wine 5.11 devel on Ubuntu 20.04.

Anyone has it running or knows what could possibly cause this?

Sometimes the latest wine breaks things. I have some Native Instruments
favorites that broke in that scenario, and worked again after installing
a stable version of wine 5.x, with the same over-rides I have with staging versions.
Pretty important, considering the rapid pace of developement these days.

When possible, set up a wine-stable setup, and keep it, experimenting
in a newer wine. A drive or SSD in a usb caddy makes for a good
bootable testing setup.

Emmisary 1.01 is working with windows reaper 5.9
in ubuntu studio 19.10, with wine 5.0 stable from
wineHQ, and some over-rides (which were not installed
on behalve of running Emissary):

api-ms-win-crt-multibyte
d2d1
d3dx9_41
gdiplus
mfc140

Thanks for the answer. I installed a few components from your list like gdiplus, but no cigar. But an older Wine version (5.6 staging) worked.

Wine seems to be more dicey after 5.8. The last releases before V5 were pretty good,
I think 4.2 and 4.3

A new plugin wrapper system is being discussed at the reaper-linux forum,
forum member nspa enters the discussion about 3/5 scroll down the page,
with some interesting information:

Turns out Emissary and some other plugins are all working now after I run
them from a clean wine prefix. I must have installed something, that broke the UI.
Using 5.10 devel. Stagging doesn't work currently for me for some reason.
First time actually everything works. Even Izotope Ozone works.

Good to see there is active development. Hoping especially for Reaper to implement some
more formats like lv2 in the Linux port. It will eventually get there.
