Does anyone have a step by step, detailed
explanation of how to create a "FADE OUT"
in a production? I've tried 3 or 4 techniques
No luck so far.

Please advise

If you are recording audio simply use the volume slider[naturally]. If you are sequencing[midi data], you will have to enter cc7 or cc11 values as you want the volume levels to fade. This will have to be for each midi channel..I use a Roland keyboard that allows the continuous controller to be recorded via the fade in/out button..

Hello,

Did you also tried the procedure explained in the "Easy Start Guide" available at the Korg site ?

My karma can do that too. and it's what I use to do fade out effects.
