Just like the effects ranges currently, with adjustable end points and intro/outro slopes. The Scratch Effect would use the same approach, with the addition of a vertical adjustment and scratch point markers. The Scratch Effect range would be applicable to standard tracks AND Overlays, with both standard mixing and beatmixing.
This would be a unique feature to MixMeister!
@Simon Bangs - I use Effectrix for scratches sometimes but it is very slow process and that is why it is unthinkable for performing life usng. And even so - not everytime works correctly and I cannot achieve everytime what I want to with it.
I also think that Jet Mmpro's idea is good...
