Yes, the keyboards have always shown this info, even my PSR 2000 showed the length of the intros. You have to know this info for coping and pasting the style parts around from one style to another.
Here are the steps:
Load your style
select the FUNCTION button
Select the "F" button which is the Digital Rec Menu
Choose the .. Style Creator
Next use the TAB button to select the ASSEMBLY screen
Now go back to the BASIC screen (again using the TAB button)
Then hit the INTRO 3 button of the style ... the screen will display the number of measures in your intro 3
It is stupid that you have to get to the screen this way ... BUT hay ... it's the YAMAHA HA HA way.
You can select any of the intros, endings and mains of the style to see how many measures each of them are. This info is very important to know as you can't copy and past a 4 measure Main Part and paste it into a 2 measure Main of another style. You would have to use this screen to INCREASE the 2 measure MAIN and make it 4 measures long.
