Ah the corrupted style problem! Same thing happened to me, now fixed using AJ's drive. In my case i had used an Apple power mac to copy henni's styles to the folk folder. What i believe happened was it copied all this empty space along with folders into the Audya?.

Once again i ask Ketron to offer by way of download a way of easily correcting corrupt setups so that the user does not have to send things to Italy. The protection system whilst i understand why, makes a farce out of the user friendliness if the Audya. Korg uses a public id to safeguard their boards, and sounds, and supply reinstall disks to correct problems when things get completely mucked up
