I'll comment as somewhat of a heretic using reaper in wine together
with wineasio/jack. I have a monolithic environment in that reaper is
the daw, and my plugins are vsts hosted by reaper either in it's own
process or in separate processes (for bridging/sandboxing). I also
enjoy all the benefits in using jack, being able to record/output
from/to pulseaudio and alsa (mostly using the alsa loopback device in
combination with zita-a2jbridge as it seems to be the best solution).
In addition I can use zita-n2jbridge to distribute audio over my lan,
and even use zita-a2jbridge to connect additional soundcards. Mostly
features I don't use very often, but very handy to just change output
in reaper and hear my mix on the laptop or tv speakers (with very
When I start reaper, wineasio creates the jack client, the server
autostarts (if not running) and wineasio auto connects the reaper
outputs to the main soundcard outputs.
When rewriting the wineasio client, it was very handy having the jack
api and I suspect that it would have been a lot harder to do if I
had to program using the alsa api instead.
What can I say, I really love the environment and think JACK is working
fantastically well. Having the plugins hosted in my daw is clearly
superior (imo), but the routing flexibilty of jack and the ease of
programming to the jack api makes jack a great asset in my setup.
As always YMMW.
