I am also having no success in audio import which appears to require Scaler Audio seems as a separate plugin according to the tutorial videos . Anyone know where we can find this ??/
You should have 2 plugs. Scaler and Scaler Audio.
Red framed are Audio Plugins (VST2 & VST3), yellow framed are MIDI Plugins.
If you use the audio, set the threshold while detecting (yellow arrow below)
. Try different levels by sliding the blue limiter mark left and right (lower or higher level) in order to find the appropriate accuracy.
