Crossfader Curve slider disallows "disabling" crossfading

[Kevin Fishburne]

I'd like to disable crossfading functionality completely, which could be implemented by allowing the Crossfader Curver slider when at the far-right position to create a vertical amplitude envelope. Currently at the far-right it's a "nearly" vertical graph, but it causes songs with no initial silence to fade in for a fraction of a second.

Alternatively there could be a checkbox in the Crossfader settings pane which, similar to the "Beat Detection" and "Key Detection" panes explicitly allows enabling/disabling crossfading ("Enable Crossfader").

Why this is an issue for you? The "nearly veritcal" setting is almost a rectangular, and should work for the most common use cases
What is yours?

Please note that "Cutting" in a song will not work anyway, since a gain jump produces a rectangular impulse witch contains a all frequencies (a click sound).
We have tried hard to eliminate those click sounds everywhere in Mixxx by fading all gain changes for the amount of one audio buffer cycle.

If audio files in the Library are edited precisely then crossfading can make them start or end improperly, as it's a countermeasure against fixed, known, or arbitrary song starts and ends. For well-procured libraries there should be an option to forgo crossfading. There have never been any click sounds, though. That sounds like a buffer/latency or client hardware issue.

In the manual case you can just leave the xfader untouched in center. In the auto dj case, set the fade time to zero.
