Thanks Mac and Blake.

I'll respond to your questions, but can I first clarify one issue.

One side of this is not about rendering. If I create a new song, save using "Save with patches and harmony", record a vocal on the audio track, and then save again using "Save with patches and harmony", the audio track is *not* saved. This is despite the status bar at the top of the screen showing an audio track and its size. Is there any way to ensure that the audio track is saved? I lose my recorded audio every time. This is totally unconnected to rendering, as I haven't rendered anything at that stage.

Mac - I'm not sure what you mean by "destructive or Realtime DXi" effects - I'm only just branching beyond singing along to the music! After recording the vocal, I used the Audio>Plugin menu to select reverb.

BIAB used to create a wav file, and then a bt0 file if I timeshifted the audio. I know once when I checked they were both there, but when I saved the file they vanished!

I have the same problem with rendering even if I've just recorded a fresh vocal on the audio track, without any modification.

Blake - It used to give the message about merging, but I haven't checked that recently - I'll watch for it. I'm just in the middle of composing another BIAB song at the moment.

On earlier versions of the song when I saved it, I adjusted the audio track volume up by 1 or 2 dB, but not the later ones. Are you simply concerned that this might be why the audio is, as you say, perhaps reduced in volume, or is there a bug so it only works at zero?

Thanks for your help guys.
