I hope I am doing this wrong, but when I make changes in SFP during a session and then hit 'save', the program appears to render/export the file. In other programs, like Audition, Audacity, Reaper, Mixbus/Ardour et al, I can make changes to the work file and then save those changes as often as I like. When done, I can then export and render the file. How do I make changes to SFP work files without having to render/export each time?
