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.

  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.

[Rosegarden-user] Jack freewheel and jack-midi and general thoughts

2019-02-23 Thread Lorenzo Sutton

Dear all,

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'. [0][1]
I also started a similar discussion specifically in the yoshimi mailing 
list (yoshimi also being a synth I heavily use in tandem with 
Rosegarden)...



If I understand correctly freewheeling is currently mostly used in DAWs 
such as Ardour or Qtractor for exporting a whole session. Cadence-Render 
[1] 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)
- jack-midi

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 :)
