Re: [Rosegarden-user] Jack freewheel and jack-midi and general thoughts
Well... I have to resurrect this and be warned, as often with my posts,
it is long :)
TL;DR: jack midi is not that easy nor optimal, so maybe re-prioritize
LV2 with audio render of projects
After a few months of experimenting and discussing, I have come to the
conclusion that I will have to contradict myself (or at least put some
doubt) about this one.
I updaeted the feature requests but will add some thoughts on here. And
this is knowing that both are huge undertakes...
So I had the impression (and still believe, at least conceptually), that
jack midi + jack freewheel would be the right way to go following a
'unix philosophy'. Now, it turns out that technically jack midi doen't
automatically mean that you get jack freewheel ('farster than realtime')
e.g. for export. And I tested this in various ways the most outstanding
was by trying to use this to 'rended' from Ardour using midi and
conencting it to a jack-midi application... Everything miserably failed
and that's because (if I understood correctly the explanation I got in
the Ardour IRC), jack freeheel while is bound to at the same bound but
not checking constraints such as disk I/O.
This would explain e.g. how other projects are dealing with it... For
instance this discussion on the Qtractor mailing list seems to more or
less support my point: https://www.rncbc.org/drupal/node/585
Now, back to LV2.
True: one can fire up (say) Carla and connect to it with alsa midi and
then record the result to audio, but as discussed many times this is
very cumbersome and time consuming, and whatever the technical solution
I still strongly believe that having to do by hand something that a
computer can conceptually do 'easily' sounds quite insane.
And let's face it, DSSI and LADSPA are dying formats, with very few
people still making or even maintaining plugins (as well as distributions).
LV2 on the other hand seems to be quite active and now has a fairly rich
ecosystem of plugin developers and users, opening up a nice palette of
sound for rosegarden users.
I write this lengthy stuff because I _really_ (really!) like Rosegarden
and wouldn't like to see it slowly die, so maybe having LV2 and audio
render would bring (back) users and interest, which I think is always
good for FLOSS under many aspects.

Gotcha... And I personally agree that #471 is higher priority than

support in Rosegarden?
It's been time to think about that for years. Just no one has time
to actually think about it. See feature request #471.
https://sourceforge.net/p/rosegarden/feature-requests/471/
But... maybe an upgrade to jack-midi would help making Rosegarden
easier to interconnect and use more of the available hosts, synths etc.
So prioritize feature request #471 above #462.
https://sourceforge.net/p/rosegarden/feature-requests/462/
That's helpful info.
I wish I had time to undertake these projects. If no one else
does, I might get to them in the next decade or two. Maybe by 2040?
They are on my todo list.
Ted.

Re: [Rosegarden-user] Jack freewheel and jack-midi and general thoughts
Hi guys, I agree, JACK-MIDI would be more immediately useful that some other features. Right now, I use that JACK-ALSA bridge program to gain that bit of extra functionality, but that is a bit awkward and kludgey.
