As some other people on LAU might have noticed a while back I tried to
open a discussion on LAU about jack freewheele as a way to more easily
interoperate between jack applications, the scenario being e.g.
composing in Rosegarden (which as you know if my favourite sequencer and
composition tool) using external synths/hosts (e.g. like Yoshimi but
also e.g. linuxsampler or Carla) and then 'exporting' the result to
audio 'faster than realtime'. 
I also started a similar discussion specifically in the yoshimi mailing
list (yoshimi also being a synth I heavily use in tandem with
If I understand correctly freewheeling is currently mostly used in DAWs
such as Ardour or Qtractor for exporting a whole session. Cadence-Render
 also seems to use this mechanism.
From the various discussions and reading documentation online it really
seems that in order for freewheeling to work one mainly needs:
- JACK transport (I think in 'slave' mode)
So the the question is: would it be time to think about jack-midi
support in Rosegarden?
There is also another side point that might be relevant here: the more
time passes the more the DSSI and LADSP olny plugin support in
rosegarden become obsolete. Personally I wouldn't be pushing for, say,
LV2 or (Linux) VST supports *in* Rosegarden, for me connecting
Rosegarden to external synths and hosts works just fine (better I would
say), as I like the idea for composing, *sequencing* and midi, which are
a different beast compared to say audio editing. But... maybe an upgrade
to jack-midi would help making Rosegarden easier to interconnect and use
more of the available hosts, synths etc.
Just some ideas :)
