FYI! Djay & Traktor Pro are not Vestax OEM software makers either but they somehow have been able to solve this problem.
Did they solve their jogs & scratch issues ???
I really don't understand what is so annoying with this.
Because a tiny bit (1 to 5% ?) of the other signal is still in the cue headphones make the software and the controller useless ?
You even call this a glitch... it's not like the pitch fader or the jog have jumps, skips or what.
I'm sorry but I have mixed hours with this setup and it had never been an issue, nor for all the guys that tried it. The main concern was the responsiveness of the jogs and controls and it is dead on.
So it's not 100% perfect in your eyes but it has reach the 99% mark what is not so bad even compared with the other non oem softwares.
