Ted, remember that each sequenced song on the 20-4-1 disk will remain in the sequencer until it is replaced by another song, or the time runs out for the memory bank. If you turn off the play button and fiddle with the remaining style, everything will be okay until you decide you want to save the style for later use. Then you run into trouble because the sequenced file will still be in memory and will include itself in the save process unless you turn it off. Then every time you load the style, the sequenced song will pop up and try to take over. To use the style properly and without interference from the sequencer, simply press the program menu button, sequencer, record and edit, song clear,ok, then yes, and it will erase the loaded song from the sequencer and it won't bother you any more. You can do it to every sequenced song on the disk and save each style if you don't already have them. You can certainly build your own archive this way. Happy playing
