Hi all ... I have a weird one. I've been exporting ranges (selecting a single song out of a set-long recording) without any issues until recently when for some bizarre reason, one of the tracks decided not to 'play' during the export. When I play the song, all tracks play, but when I export, the kick drum track doesn't go. I can see the small level meters for all the tracks and the level on the kick is basically 'off' during export.
The only changes I made before this started happening was to add a couple of busses; one with a reverb plugin to send snare/toms to and the other with a delay plugin for vocals. These are working fine. I also changed the export settings from 16 bit to 24 bit since the previously exported stereo file seemed to be missing a bit of punch in the low end. What does export now sounds much better when listening to it in Audacity or Audacious, much closer to how it sounds when playing the actual mix in Ardour -- except that the kick drum is missing.
As I mentioned, I have exported this same range a number of times before adding the busses and switching from 16 to 24 bit on the export settings, with no problems other than the quality not being as good as it should be. Note that I have not switched the export bit-ness back to 16 yet to see if that is the issue. Regardless, exporting at 16-bit isn't giving me the quality I need so I do want to get this working properly with 24-bit.
Anyone experience something like this before?
