Need a Tutor for Reaktor 6 -to build complex sample/granular instruments with GUI's

As far as your scope issue goes, I always prefered making them using XY modules, I never really liked the primary "scope" object.

Here is a macro showing you how to do it, it's really pretty simple.

hope this helps.

It just need a pitch input from the midi input, and a gate to trigger phase sync and then an audio in.

You can also change the color of the XY area display from the reaktor preferences panel in the left sidebar.
