Where can I edit Voices within the style parts, vol, efx, etc,.....
and/or change drum sets, or drum perimeters etc, etc, and re-save to registrations, had etc..?

>>>AJ:- This is down within the VIEW screen when you select a style.
• Press VIEW on the bottom lower part of screen to access the STYLE VIEW – all parts that make up the style.
• This default page shows the VOLUME of all the style parts. To access say the PAN (left/right), REVERB, CHORUS, EFFECTS ..etc of all style parts, use the equivalent buttons below the screen. Once selected, their parameters can be changed by pressing the number corresponding to the parameter you want to change, and turning the wheel to change it.
• Press DRUM MIXER to access the individual drum parts (volume and reverb).
• Press DRUM to access parameters associated with the drums such as:-
o VAR3 TO GROVE (On the main STYLE VIEW screen, you have 3 VARIATIONS. If this button is off, all 3 affect chord parts only. If this button is on, the 3rd variation is for GROOVES that affect the drum track (when turned on/off).
o AUTOFILL (Auto Fill in in when you switch between Variations)
o Fill To Arrange (When you press the FILL IN, the arranger automatically switches forward/backwards to the next/previous – depending on which FILL in you press.
o AFTER TOUCH FILL:- Press hard on the key to activate the fill in … no need to leave the keyboard and press a button for FILL IN anymore. Combine any of these for true musical freedom and creativity.
• When you are done with the modification .. remember, you just modified a FACTORY style. You must now save this style as a USER STYLE by pressing SAVE and given it a name. Then go back later to the USER STYLE location you saved this under (EG POP), reload the style, then set up the voices and other parameters – then press SAVE and SAVE REGISTRATION – to save this setting under a REGISTRATION.
