Realtime export for users of outboard equipment
after quite some experimenting with plugins, I recently went back to using outboard reverbs by TC.
One easy way of integrating such a reverb is to plug into the SPDIF I/Os of your soundcard, sending audio to it via a bus in ardour, and routing the returns into another bus in ardour.
However, to export a track, this requires to play it back and record Ardour's main out with jack_rec.
How about an realtime option in the export dialog? Basically the same thing: play back and record from main out.
If my budget were unlimited, I'd go for the real expensive TC reverbs instead of the quite good M-One XL (and I'd donate more to Ardour, of course.) Furthermore, I would switch to a TC Finalizer as a mastering processor in the main inserts. These external devices can even be easily stacked over one single ADAT connection (each device picking its two channels from the ADAT stream).
So I think even for very professional usage scenarios, there would be good reasons to have such an option.
