I had almost similar problem with my Pa4X while ago on the stage, not exactly like your issue.mintjamman wrote:To be honest until today I have never noticed this issue but I now notice that when selecting a Setlist Entry the Song loads, Press Play and everything is as mixed. Stop the Player, now when you play the Pa4x the volume levels of the selected parts are about half the volume thet were. Now select Play and the volume is back at the correct mixed levels, this can be replicated each time.
Anyone else notice this, I am certain I would have picked up on this before
Whole volume's styles and keyboard sets were dropping during the live performance.
I was using the TRS audio cables according to the Korg Pa4x website.
Problem was resolved when I replaced the TRS cables by TS (Mono)cables from L+R outputs.
Did you try by a headphone?
I think it's not hurting if you can try with another TS cables in case you're using the TRS cables with your PA system.
Just trying to help and I hope you can sort it out soon.
