Right, - Since my last post I've succeeded in producing a MP3 Audio file from the CanonGuitar.sgt file... Yes! - It works and repeats! - Without closing down MA3. - Then, whilst MA3 was still open, I ran the .sgt file again and the aquarium closed down after a single run-through.
So to me that's conclusive that my system can't repeat files with the suffix .sgt - Next thing is, WHY?
Edit,
Mark, - I did just rename it as a .mid, (which didn't play), but would then convert to a MP3 in a prog that I'd downloaded.
Nicki, - The prog I just used is, 'Switch Sound File Converter'. - It seems to have done a similar thing. (4,950 KB).
