[solved] t-racks vst crashes fl-studio

[dhomborg]

Hi,

I've had several projects of fl-studio crashing. All crashes where caused by t-racks VST's that were in the project. The crashing was not consistent, sometimes a project would load, but sometimes not. After investigating i created a testproject which crashed constantly which made debugging more easy. After a couple of days i found that the crash was caused by t-racks VST's that had their window gui scaled. The vst seems to remember the scaling, so after i created an empty project i inserted all t-racks vst's i used, rescaled their gui to 100% and exited fl-studio. After that the project that crashed all the time opened without issues. I'm sure rescaling will work for some people, but i hope this post will help someone who has the same issue. T-racks sounds great, but after all the crashed i had i was very cautious about using it in projects.

I'm just experiencing the same issue as you. Sometimes the project would be loaded correctly, sometimes not, causing FL to freeze without any error log, sometimes with some logs which I've sent to image line support, and still waiting for response. I've made also a clean OS Windows 11 installation for troubleshoot the issue. Everything is ok until I engage some of the T-racks plugins, then it is a lottery.

I still have some freezes/crashes sometimes. seems the scaling does not really persist to default all the times. As i expect it to be a graphics issue, what is your video card? mine is a GeForce GTX 1080.

I'm currently using lenovo legion 5 laptop with RTX 4070. I'm going to test it also on my 2 PCs with exactly the same FL project that is causing the problems. Will let you know the results.

you can also look at the file
C:\Users\[username]\AppData\Roaming\IK Multimedia\T-RackS 5\settings.properties
in this file there is a line with scaling values:

<GuiScaleValues ScaleRatioWidth="1.023529410362244" ScaleRatioHeight="1.023746728897095"/>

editting this file and setting both values to 1 sometimes help me opening up a project when it crashes

<GuiScaleValues ScaleRatioWidth="1" ScaleRatioHeight="1"/>

Same here in Cubase and Bitwig.

It happens also with the new T-Racks 6 Maxx Plugins.

It's a pitty that nobody from IK MM is supporting here in the forum.

But thanks for your investigations so far. I will try the work-around and let you know about the results.

BTW: I have also an Nvidia Graphics Card. Mine is GeForce RTX 3050. Could be a GeForce related bug?!

The good thing about Bitwig compared to other DAWs (e.g Cubase and Ableton) that it is able to stop only the affected plugin and I can get at least this information out of the engine.log of Bitwig:

In the meantime I tried the suggested work-around without success.
Setting the scaling in the settings:

c:\Users\Soilw\AppData\Roaming\IK Multimedia\T-RackS 6\T-RackS 6\T-RackS 6.settings

doesn't help.

I also see, that it has something to do if the project is loaded already a with a lot of plugins and tracks or Not. When I start a fresh project and only have one track with a IK MM Plugin inside and reload it, it still works.

After a couple of tests and installing the latest graphics card driver I could made an additional observation:

Only a few plugins seems to be affected. e.g. CSR Plate

So most of the plugins seem to work, which brings me to the conclusion that some of the T-Racks plugins might be buggy. The T-Racks6 version of CSR Plate is crashing, but the T-Racks5 version is suddenly working in Bitwig Studio. Before I upgraded to version 6, I could also see the same crashes in Cubase 13 with CSR Plate.

Hello again.

I was able to solve the issue by re-installing T-Racks5 and now suddenly the issue in the T-Racks6 version of some of the buggy plugins is also gone?!

I don't know why this helps, but it helped. Logically speaking it doesn't make sense for me.

But at least I can work now again.

Have a great time.

Cheers
Paddy
