Roland Cloud plugins crashing in AudioPluginHost on Windows (JUCE 6.1)

General JUCE discussion

Hi all,

AudioPluginHost is crashing when I instantiate any of the 3 instrument plugins I currently have installed (System 8, System 100 and Zenology Pro).

Exception thrown at 0x00007FFB6D9DA3B2 (SYSTEM-8(VST3 64bit).vst3) in AudioPluginHost.exe: 0xC0000005: Access violation reading location 0x00000000000001A8.

Here’s the stack (it’s the same for all 3 plugins):

Is AudioPluginHost doing something wrong perhaps? The plugins are working OK in the other hosts I’ve tried.

Many thanks,
Ben

I just tried AudioPluginHost in JUCE 6.0.8 and the plugins work OK in that too, so it looks like a regression.

Thanks for reporting. This has been fixed on the develop branch here:

Fantastic! Thanks for the quick response. I’ll test it and let you know the results in a day or so.

Thanks again,
