On the Tyros 2 you could easily assign the Mod Wheel to the Leslie slow/fast effect to custom voices. The Leslie effect would have a ramp speed from slow to fast and visa-versa.

On the T4, I cannot assign the Mod wheel to the leslie effect on a custom voice;

On the White Bars Patch; the Leslie effect on the Mod Wheel goes from slow to fast instantly; no transition or in between which for me is not authentic and sounds like getting splashed in the face with water.

On the Organ Flutes screen, you can press the F4 button and the Leslie will transition nicely from slow to fast using the correct transition speed, but you cannot assign it to the Mod wheel. How are you supposed to control this during a live performance from the Main Screen? You must have the organ flutes screen up all the time. Grrrrrrr!!!!!

Has anyone had luck deconstructing the T4 Organs and creating usable custom voices that were similar to the previous Tyros models or traditional Hammond Sounds?

Thanks
