Hi @rjbouman
Welcome to the forum, and thanks for your descriptive post.
We haven’t been able to reproduce the issue you’re seeing on either our Windows or Mac machines. A one-bar chord is displaying correctly as one bar long in the MIDI editor.
If you haven’t already, we recommend rebooting your computer after installing Scaler 3. If you’ve already done that and had a previous version of Scaler 3 installed, a clean reinstall is also recommended – especially when oddities like the one you’ve described appear.
If the issue persists, please let us know and we’ll investigate further. Cheers.
