This problem is also in the regular trunk. Unlike in v1.7.2 Traktor Vinyl does
not work at all.
Will file a bug for that.

Only If the "Play" button lit, the Pitchfader /BPM Display /Pitch Rate are
showing changes.
If the "Play" button lit i noticed the BPM and Pitch Display are rapidly
changing( around +/- 1BPM) , tested on 2 different turntables.
I use Vestax PDX digital turntables, but there might be slightly higher
fluctuations in speed with other turntables too.
So your "steady pitch for 1/2 a second" might be the problem here?
There is also another thing with that:
- Play a track, lower the pitch to 90% and hit stop.
- Continue playing the track , now it plays at 100%, not 90%
- After a moment the "play" button trigger kick (sometimes) in and the pitch
goes down to 90% again.

Strange, looks like qDebug emits only to the console when the "Play" button lit.
I kinda moving in a circle.
Could snatch 2 values per side when End-Of-Record blink was randomly working.
Site A 1484253 & 1486612
Site B 2092078 & 2089857
Hope it helps at least, was like starring on a lava lamp.

This problem is on all platforms cause you use a transparent png (Rectangle).
This Rectangle overlays all the other controls "behind" itself.
I.e.if you move the mouse over the BPM, you`ll get the Rectangles tooltip.

Has the "Lead-In time " in Preferences->Vinyl Control any effect? Have tried
anything between 0-10 sec with no effect.

I only came up with this cause it is listed on the Traktor vinyl as feature.
Not sure if it is used in the field at all.

Nah, i should write more clearly. The thing i am looking for is to control
Mixxx with 2 turntables and an external Mixer.
Like in Serato Scratch.
Actually the track stops playing in that very moment i cut the sound of the
Control Vinyl ( i.e. while scratching).
