Help with 'Save as audio track' -Sibelius 3

I am writing music for a video game that one of my friends is making. I am using Sibelius 3 to do this, and when they are complete, I use save as audio track to save them. However, there is a problem - Since I am writing for a game, I am writing all music to be looping - that is that it repeats forever - and the problem with save as audio track is that currently, at the end of each track, for some reason Sibelius sees it as necessary to put a random 3 second gap there. This is most inconvenient, I was wondering if there is any possible way to remove it, or if not, a program that I could use to do the same. Pressing cancel just before the end of the track doesn't work. Thanks.

I don't know how 'Save as Audio File' works in Sibelius, because I always import MIDIs from Sibelius into Cubase and make MP3s from that. If you use a program like Cubase you can easily load in your music file and cut out any space you want. If I were you I'd look into using a program like cubase(allthe other names escape me for now), and use sound banks and samples to make your MP3s.

If you want to make it looping you may have a problem other then the gap
but here is how I would do it. I would repeat the music in sibelius 3X (copy, paste paste)
then I would save it as a wave file and cut off the first and the last part in a wave editor.
with some trial and error you'll probably succeed to create a good loop.

Now, why the middlepart of 3 repeated sequences?
because Sibelius has reverb ("echo")
it would be audible if (with the start of the loop) reverb level would drop to zero.
by repeating the sequence 3 times you might find it easier to cut out the loop.
If the loop schould start were the music starts you may have a problem, if the music sequence ends loud and the sequence starts soft (because of the reverb)

Does anyone know where I can get a copy of a program like this? I don't have one currently. Are there any trial versions going at the moment that I could use just for the 15 or so tracks that need done?

If you don't find any, I will do the loop-making for you

Use something like Audacity or Goldwave (both free). Great, simple & quick audio editors/recording programs. You can set it to record MIDI, WAVE, whatever, then trim down the beginning and end of your piece, so it'll loop.

I just got Audacity, and succeeded in eliminating the gap at the end of the track. However, I did not realise before that there was also a gap at the beginning, and insofar I have found this to be uneliminatable - at least, not without taking some of the music with it! This is rather more difficult than I had imagined.

In audacity, zoom in (zoom tool), and then trim the beginning off. It's really easy.

Ah, thanks. I shall try again now.
