VST3PluginTestHost 64-bit processing

Developer VST 3 SDK
1

Hello,

I’m trying to use the VST3PluginTestHost for 64-bit processing for my plugin but it just output silence.
My plugin works in Reaper

		if (data.symbolicSampleSize == Steinberg::Vst::kSample64)
		{
            // process here
		}

If I just change to process kSample32 in my code it outputs audio from VST3PluginTestHost, so I know 32-bit works just fine.

Is VST3PluginTestHost supposed to work with 64-bit processing? Could not find any settings in the application regarding that

The test host does not support this.
