How can I disable the gap killer via pal script for

a) the next song in queue

b) globally until gap killer is activated again?

To a):
It is possible to disable gap killer for one song manually by opening Song information editor for this song, setting Gap Killer = Disabled in "Settings".
However, I can't find the setting in TSongIngo object. It might be hidden in "xfade" or "flags".

Any clues?

Gap killer is a global setting. To the best of my knowledge it cannot be controlled by a PAL script.

You can enable/disable and assign different crossfade settings for a particular song. That may help you do what you want. Check the Fading tab in Song Info.

I just found out that the you can set the gap killer setting for each file.

SongInfo['xfade'] must contain '&ge=1' for gap killer DISABLED
SongInfo['xfade'] must contain '&ge=0' for gap killer ENABLED
SongInfo['xfade'] without '&ge=...' for gap killer global DEFAULT

Take care, 'xfade' can contain other values as well. Don't just overwrite the settings.
I am working on a nice function for PAL and will post it later.

Learn something everyday. I've looked at Song Info hundreds of times and never once noticed that control because I never had the need for it. Talk about a blind spot!

Yeah, xfade is a string with which one wants to not mess lightly.

… and unfortunately XFade is language settings-dependant … so I had to convert 22,000 files to work on a German Windows!

(The XFade &bmp= [sic] setting for BPM stores the decimal separator that is used in Windows’ regional settings, not a uniform ».«. This is why I had to re-tag all my files to contain BPM settings like »&bmp=120,5« instead of »&bmp=120.5« to make SAM understand the BPM values on a German Windows. Sigh.)

@ Roman12: Sure you haven’t accidentally exchanged »enabled« and »disabled«? As far as I remember, &ge=0 is »Gap Killer Enabled = false«, i.e. no gap killer.

Ouch! That's why I'm hoping those settings will be in a separate table or at least separate columns in the future. That way they can used for other things like event triggers, e.g., play a certain drop when a certain point is hit in a song.

And I hope for more support of the Tags that are defined for some things … It’s actually some work fiddling around with »XFade« in Mp3tag, but fortunately we have RegExp.
