Chony, when you're in Mixing Console Style Effect screen highlight DSP1 & push Type (F) then push Parameter (F again).
Now scroll down the box that appears (using the 5 Down button) till Connection is highlighted.
Change the Value from Insertion to System.
Hope it works for you

Thanks John, that did the trick. I wonder why it greyed out in the first place?
Perhaps you could answer this one too: For some reason when I apply effects on an instrument in a style it doesn't sound the same as when the Yamaha engineers did it on theirs. For example the Yamaha rock styles have some luscious sounding distortions on their guitars, but when I use the exact same distortions with the exact same parameters on mine, it still sounds like the original (uneffected) signal is coming through behind the effect. I tried playing with the settings but didn't get anywhere. Perhaps you'd know?
Thanks, Chony
