When I import new audio into logic 7.2.3 - often it will first say that is creating wave forms for the display. Q: I notice that the audio files on disk do not show an altered modified date - so where are these wave form displays being saved - on the audio file or inside the logic song? Q: I am interested in possibly going back and forth between logic and Pro tools LE - and at different times using the same audio files for both platforms. Assuming I am not doing any destructive editing - is it OK to use the same set of files for both platforms - or do I need to make duplicates (I'd rather not)? Also, how does this wave form display get dealt with by going back and forth between the two platforms? -- Thanks - RevDave CoolCat@hosting4days.com [db-lists]
