VSTi Crash in Ableton Live OSX

Audio Plugins
1

A user reported a crash in ableton live while using the VST plugin. I couldnt reproduce it in a simple project, but he sent me a crash log and it looks that the button listeners produces the crash. Here are the steps that lead to the crash some times:

I have now managed to recreate the crash several times by playing the computer keyboard as a regular keyboard for the VSTi Plugin, than opening up the interface and trying to adjust something, which in several cases ends up in a crash.

Did you ever get any help with this? I am encountering a similar issue on Windows 7 x64 and Live 8.2.5

No. I had no chance to fix this because i couldnt reproduce it on my machine and even the bug reporter couldnt reproduce it reliable.
Updated to the latest tip and didnt get any bug reports about this anymore. Maybe the problem still exists.

Be carefully when you update to the latest tip. You maybe run into follwing issue if you make a vsti where people play the synth with the laptop keys and modulate the sound:

The keyboard issue is something i had with my morf plugin. But i managed to fix it. It looks like Live passes keyboard events to the plugin and does that in a loop until your plugin “eats” the event. So i had to add a keyPressed() callback to my plugin editor and return “true” in it, in all other cases Live would either hanG or crash, while the plugin would be in an infinite loop calling the keyPressed() method.

If you want to look at the code it’s here https://sourceforge.net/projects/morf-wrapper/

I noticed that the flag “Plugin wants keyboard focus” makes no difference.

Thanks for the information. Sounds exactly like the problem here http://www.rawmaterialsoftware.com/viewtopic.php?f=8&t=11290. I will try it.

Thanks! This was the problem. I don’t think you have the latest code hosted on sourceforge though, I couldn’t find the keyPressed() event in your Editor.
