Case closed!
This is getting off-topic and OP wisely hasn’t participated in that off-topic discussion for 5 days now.
@Thealz: Sorry if you didn’t get the best answers. There isn’t another workflow to get better FX really. If you feel they are not sounding right, then that’s basically it.
The best part is that DenonDJ can change or add FX (they did the same on the X1800), as they are not printed on the surface. It means you have to wait for better days…but your issue with the FX is in the present. The community can help to create better FX, so if you’re up for that, please do make a request.
If you don’t mind, I would like to close this topic within 24 hours if it stays off-topic.
