Hi folks, sorry I was so vague. I set up a panel memory with 8 sounds. I then did a quick record using some of these. I then saved to SD card. When I heard the songs many times, I decided they would sound better if I changed a voice or two. To give you an e.g. I started a song with vocals, which in my opinion went on too long. That's why I wish to change. I can'tgive any more information, sorry. I have changed the voice whilst it is playing, but I don't know how to make it permanent. Many thanks for your help, Jess
