Look in "open special" and open up the backup file that Realband automatically makes of your seq files - unless you've changed the default settings, the last 5 versions of your seq file should be there. Once you find the file with that track on it, you can simply work on the project within the backup file, keep and change whatever you want and then save as another project name when you're done. Or you could always export the file to a wav from the backup and bring it in to another project.
