On Super Sunday, I used the Korg Pa4X at my contemporary worship service. I have 200 plus backing tracks that I have made for services over the last 12 years. So, I transferred the 4 songs I needed from the Yamaha Motif ES7 to my DAW. Then I processed it and exported a WAV and MP3 of the tracks. Then I put them in a folder (Sunday Songs) on the thumb drive I use for the Pa4X. I add the 01-02-03-04 to the file names to put them in service order.

Song mode
Select the folder on the thumb drive
Select the file
Play
Control volume of the song on the MP3 slider
Control my right voice 1 volume on the slider
Play piano to the song and sing like normal

Only problem... the output level of the Pa4X is less than my Yamaha Motif ES. I'll fix that for next Sunday.

12 pounds lighter
Great piano sound
Great control of background tracks

People liked coming up to look at the new keyboard.
