There are several ways to add this line, but probably the best way is to use an excellent program called CasmEdit. You can find a link to it on Jorgen Sorensen's equally excellent website at home7.inet.tele.dk/js/musik/740pages/ . Clink on PSR links and then software. You might want to look at a PSR style first to see where the sysex goes and then update your styles accordingly.
