   there's no limitation on lv2.

   i think you misunderstood something, but any lv2 host has obvious

   your question seems to pertain on rendering audio that is produced
   by midi
   instrument plugins _faster_than_realtime_ .

   i also think you are inferring from qtractor as the sequencer. that's
   true: qtractor cannot render midi instruments audio in no other
   way than
   real-time. so that for you to export the whole session (song or
   project)
   you'll have to bounce (record) all midi instruments audio output
   into spare
   audio tracks and then, when all is perfectly realigned to
   compensate for
   round-trip delay, you can mix-down and export all audio tracks into a
   single audio file.

   theoretically, any jack-midi plugin host can do the
   faster-then-realtime
   trick, thanks to the jack-freewheel mode of operation. alas,
   qtractor is
   not a jack-midi host, although it does the freewheel dance to
   export audio,
   as ardour2 does. speaking of which, ardour3 may well confirm this
   theory ;)

How is that done on Windows then? I never heard of any problems there? When you use VST, it renders them fine
and Windows has no JACK.

ps: sorry if my questions are silly, I really am trying to understand

Are you asking for doing a stereo mastering without playing and recording the song? I wonder if this is needed. Anyway, I'm not sure if I do understand what exactly you are asking for by the word 'rendering'. Is the host Qtractor? And do DSSI plugs what you want?  I guess 'we' do misunderstand what you're asking for, by your first email.


No, I mean hitting "Render all song to wav" and have everything in one file.
