Input level defaults to 40?

Maybe!
But I have found no possibility to set this parameters (LP-16/Win 8,1 64bit)

Whatever I do:
If I did not push up the levels to 0dB on every track the track will be played with less level.
There is no way to set the output to “pre-fader”.
pre/post-buttons have no effect for playback the tracks.
The buttons “Monitor Mix” and “Direct Out Mix” are not visible in the mixer window.

[Edit]
When using in uTracks24-mode (in settings) the buttons are visible!
