Just for fun, start by setting the Attack (F1) to 12 instead of 0. What was a piano almost sounds like a whistle. I just had you do that so you would know how the Attack works. Reset it to 0. Now on the left side of the screen do the following.
F2 Decay 66
F3 Sustain 67
F4 Release 65
F5 Level 80

ON the right side of the screen you have some extra options.
F6 Resonance to minus 64
F7 Cutoff 127
F8 Effects -- When you press this you get a different center on your screen.
The effect type will be highlighted. Press your right "Value" button until the effect type shows Delay~Chorus. Then use the "Cursor" button until Reverb is highlighted. (you can set the type of Delay and Chorus, but the defaults "Delay1" and "Chorus1" are good for now.) Using the "Value" buttons set the Reverb to 63. Then move down to the "Delay" using the "Cursor" again and set the Delay between 18-63. Be sure the Delay is plainly audible. Then repeat this procedure and set the Chorus to 63.
F9 Wheel -- Pressing this gives you another screen in the center again. Use you Cursor buttons to get to LFOamp and set the value with the Value buttons to "On". Do the same with LFOfilt. Turn it on. Then Cursor back up to LFOpitch and turn it off. Note: you cannot turn LFOpitch off until you turn something else on.
F10 -- Yet another screen display! Using the above procedure toggle down to LFO2 Rate and set it to 56. Go to DFC Depth and set to 49.

What we have done on the the F9 and F10 settings is change the action of the Modulation wheel. Instead of changing pitch it will have a Tremolo effect like the old Wurlitzer piano and some of the Rhodes pianos.

Press Save/Enter and F10 only if you wish to keep this setting.

You have 128 voices that you can do with what you wish. The way these voices come defaulted from the factory, are very similar to the regular voices in your voice banks. Using these techniques, you can choose to have a very different set of voices.
One further item. You can use the voices in your program settings to give your program voices a different sound. However, the effects, will not follow the voice since you set the effects in program.
