Dnj,I think that's the FX adjustment for individual sounds or styles, what I need is EQ for main output.
When I change some FX to EQ it affects all the sounds...and when I change style other parameters (even other FX)are choosen.
For me it's a difficult part of the keyboard.
I think it's more fun to please the neighbours with my play,lol.
Most of the time I use headphones.
Thx for helping me out.
