IK TRON with SampleTank3 or another Mellotron plugin that works as it should.

With the original Tron interface I was able to set the timing correctly with like Telentmaker loops and other loops that have rhythmic elements. If the timing is not set correctly [not default] the loops slow when going lower on the scale.
Dose anyone know how to solve this issues? 
 
 
or another plugin that works like this..... https://www.youtube.com/watch?v=tTKPW92ndUA on the rhythm side.
