On my GNX-3, I tried to change the record quality mode from CD to LP or EP and it won let me change the setting. Why?
If you have any tracks or material pre-recorded on your GNX-3, the record quality mode will be “locked in” to the mode of the first track. In order to change this setting, you will need to delete any previous tracks that were recorded with the other mode or erase the song. The record quality mode of the first track recorded on each song determines the record quality mode of all the tracks for the entire song. Be sure to set the desired mode before recording any tracks.
