Hello Ivan,

There is little improvement. I can now get correct sound on Logic Au / Juce Developer Branch version. Before the sound was flat without the convolution.

Still no convolution effect on Ableton Live / Vst version; both Juce Developer Branch and Juce 5.1.2.

Any idea why Ableton Live e.g. VST does not run the convolution ? I have played a bit also with the buffer size settings on the DAW.
