no sound in ACC slots (sorry this is long )

[al urezzio]

first off , i am using my pa3x very different from everyone else ..i had redone many styles to fit my original & cover tunes , than save them to the favorite banks ..seems the SONG section i never could figure out & seem slow calling up a song on stage ...so now here's my problem .. ive been reworking my original song / styles .what i have come across often , there will be an instrument showing on the last 3 Acc slots , but NO SOUND in any of the variations . if i change the instrument , still no sound .do i need to go into the Record/ write mode & fill them in that way ..i am not very competent with using the write sections .but this no sound instrument is showing up alot .. last time , someone asked what style it was ,then checked it out on their keys & it had sound , dont no how to explain that .. many have sent me zip files with their custom styles that have worked out great ( and i can always use more if anyone has some ..please go to https://soundcloud.com/urezzio-al , you can listen to my original live recordings ..
ps if anyone can recommenced you tube videos ( in english that would help , it would be appreciated ...
