Hey Patrick, thanks for your reply, good to be here.
Let me try explain with my pour english.
I just would like the sound keep on (fadding) for some time after I release the key, a little sustain in all keys, without need to press the sustain pedal.
I have a Yamaha DGX 660 and that is possible but so far I didnt found how to do that in the Privia PX S3000
