Hallo Larry,

Here is how you can lengten a song.

First off all you load the song into your keyboard.
Press the program menus buttom and then select sequencer from the options in the display.
Now select copy and past followed by measure copy. Now you can select the section of the song you want to copy and the pasting it to the measure where you want to begin it playing.
In the left box marked ,from , you set the tracks to all, and the measure where the section has to begin and the last measure of the section you want to copy.
In the right box marked TO,you set the track to ALL and then you give in the start measure and repeat 0 or 1 or 2 (it depends if you want to play this part several times). The start measure is the measure where you want to begin the part you copied.
Confirm all these settings by pressing OK followed by yes.
Don't forget to save the song when you are sattisfied with the result.

Greetings from Belgium,
Alain
