Headless exporting of dawprojects to audio files?

[locallycompact]

Hi. Could or will it be possible for bitwig to headlessly export from a .dawproject directly to an audio file from the command line without invoking the UI. This would allow for experimentation in programmatically generating the XML and being able to produce audio artifacts in continuous integration. Is this something bitwig would consider? I think it could be really powerful and cool.

@NickJAllen do you know?

Hi, still wondering if anyone can answer this.

I also think this is really interesting. E.g. for training of neural networks for music generation.

Although that would open the door to someone who just wants to run Bitwig Studio on a webserver for others to render their dawprojects ;-)

I just added another issue (#52) for embedding audio master files into a dawproject file. Combined with this it also could work like this:

• run Bitwig Studio headless with an input dawproject path argument and an output dawproject path argument
  • basically: "import the input dawproject and re-export it to the output dawproject path"
  • this strips all dawproject features that Bitwig doesn't support!
  • additional command line option: "--render_audio_master"
  • this way the output dawproject then would contain a rendered master audio file
  • tbd: where to define the arrangement time range/channels to render? (as command line arguments or in the dawproject itself)
  • I think having the result as an dawproject again would be very good for additional evaluation afterwards!
  • (you could detect and handle whether parts of your generated input dawproject have been stripped on import)

I'm also looking for a way to render dawprojects to wav directly from the cli. Any news from the Bitwig team about this feature?
