Hi Jack; Styles are in the CUSTOM folder. Unless you have the following setup the KN7000 will not see them. PRIVATE/TECHNICS/KN7000/CUSTOM. Without this structure the KN7000 will think the SD card is empty of styles. Files (songs) with a MID file extension will not show on the KN7000. The MIDI files have to be copied to the SD card through -- SD TOOLS - SD-SOUND TOOLS - COPY FROM DISK. Hope this helps. Dick
