I'd like to be able to do this:

1. Put a deck into slip mode
2. Spin the jog wheel back
3. Exit slip mode while the wheel is still spinning
4. Song immediately continues to play from the "un-slipped" part of the track.

What actually happens:

1. Put a deck into slip mode
2. Spin the jog wheel back
3. Exit slip mode while the wheel is still spinning
4. Song continues to play from the "un-slipped" part of the track AFTER THE JOG WHEEL STOPS SPINNING
   --- The song seeks to where it should be, then begins to spin back because the jog is still sending midi notes

I would essentially like Mixxx to ignore midi notes from a spinning jog wheel on slip mode exit until that wheel stops sending midi notes.

Here's one way this might be accomplished: It would be nice to have something like a "control stopped" event that would fire when a particular control stops moving (ie: no data from it in a certain number of milliseconds - maybe you could set the threshold for this arbitrarily somehow), that you could hook a function to with engine.connectcontrol... Then, at the point in the script where you call the exit from slip mode, you could disable the wheel input, and re-enable it in a function connected to the "wheel stopped" event.

I can imagine uses for this other than for the wheel/slip mode thing - interesting functionality could be built around a "control stopped" function for knobs and faders as well.

Yes, this could be universal solution.

I experience problems with the touch sensitive wheel of the RMX2 Controller.

Touched = Scratch
Not Touched = Jog

But while scratching it sometimes happens that that you accidentally release the pressure and you are back in jog mode.

Whit such a "control stopped" event we may script around it.

I'll take a closer look at this when I have some time, but for now, can you guys take a look at the wheel script functions in the Reloop TerminalMix4 preset I created? (I think the American Audio VMS4 preset does it too.) They feature the ability to do a spinback and the effect remains engaged even if you stop touching the wheel, until it stops moving, then the track resumes playback, exactly as would happen with a moving platter.

Scratch that... the functionality is already in the controller engine in Mixxx v1.11 so it should just work. If it's not, then the added brake & spinback code might be affecting it.
