Module music files were ignoring pattern jump commands used to loop, and instead repeated from the beginning. These files will now loop correctly when the sound is loaded with repeat=1, but please note that it will not be possible to turn the repeat setting off; the sound must be cleared by sending a null sound to its channel, or stopping all channels.

This issue has been resolved.
Descriptive Problem Summary: During playback, when you have a B-flag (position jump) set to jump to a pattern before the said B-flag (such as from Pattern 5 to Pattern 3), Dream Seeker will jump to the beginning of the song instead of jumping to the specified pattern of the B-flag. Everything after this B-flag is essentially dropped.

Numbered Steps to Reproduce Problem:
1. Open up any .IT file in a tracker.
2. Set a B-flag to jump to any pattern before the B-flag.
3. Play the file in Dream Seeker.

Code Snippet (if applicable) to Reproduce Problem:
sound('file.it',repeat=1)


Expected Results: Dream Seeker jumps to the specified position of the B-flag during playback.

Actual Results: Dream Seeker starts the song over upon reaching the B-flag during playback.

Does the problem occur:
Every time? Or how often? Every time.
In other games? All games that use .IT files with B-flags.

When does the problem NOT occur? This problem does not occur when you're jumping further into the song (such as from Pattern 5 to Pattern 10).

This is a known issue (although I can't seem to find where it's been reported before)--unfortunately the issue is with FMod. If there's a way to get FMod to respect pattern jumps I'm not aware of it; Google is a wasteland when it comes to information on this subject.

This may be resolved in a newer update of FMod, so we can look into testing & integrating that.
