When you play a Standard Midi File and the links to the real time[arranger]parts are on, the edited patches from the SMF will be in the temporary memory. You can save this into a Performance memorie. You can turn on the parts you want and turn off the ones you are not interested in, then resave to a performance location. When you want to use a performance patch with other styles or whatever, use the tone lock to retain the patch as you select other styles..Fran
