something I would like to use more often is Super-Clips in the Audiomontage.
But there seems something strange with Mono-Files, which happens with new created Montages and my Presets.
When selecting the clips and render them on a Mono-Track, I receive an empty new clip with no audio.
When opening the Super-Clip I can see and hear the right audio.
Working with Stereo-Tracks everything seems to work as expected.
This is on a Mac Pro with 10.12.5 with Wavelab 9.1 - but remember this not working since some Versions.
Hope there is a solution.
