How to increase through/ punch of any sound in Korg X50

[deshwani]

I have Korg X50, I play it with my band that sound is heavy with drum, lead guitars, bass guitars, when we plays together my X50 sound comes very low compare to guitars and drums, its through/ punch is too low.. Only brass sound is heavy but all other sounds are very low and everytime I have to ask sound operator to increase my X50 volume on highest level but however its suppressed. I had Korg 01W FD before this and that's sound quality and through/ punch was very heavy and it was doing very up compare to guitars and drum.
Can anyone help please how I increase the power of any tone while editing?
Thanks for help.
