I'm not at my keyboard at the moment, but apparently Yamaha is telling me you CAN map a Musicfinder entry to a Registration by using the Memory key and pressing the registration from the music finder screen????

Please see the response from Yamaha Support:

Al,
Regarding model:TYROS4
To have a music finder setup mapped to a Registration, simple call up the music finder you want to use, then press [Memory] then select a registration. Only certain organ patches have the DSP assigned modulation. It is not an assignable feature.

How can I map the Musicfinder entries to a Registration entry on the Tyros 4?
also..I would like to change the way the Modulation wheel works on a Custom Organ Voice. When I copy a FullBars patch, the Modulation wheel controls the volume of the patch. I want to modify the custom voice/patch so that the Modulation wheel controls the Leslie DSP effect.

How do I do this on the Tyros 4?
