I've been experimenting recently, and trying Csound (with the Blue
frontend) and Ecasound (with the excellent Nama terminal frontend),
and have a question.
Has there been any comment or discussion about adding jackmidi to
Csound and Ecasound? Is this an option for further consideration given
jackmidi's excellent timestamped structure?
Has anyone experimented with this, i.e. hacked a version?

Hello Aelx!
I know, that I didn't come across anything ecasound+jackmidi. Ecasound ALSA
MIDI support is quite basic. That's why Nama tries to combine Ecasound with
midish, which again doesn't do jackmidi. I didn't come across any jackmidi CLI
app yet. At least not in the sense of a sequencer or other directly musical
tool.
But still, Ecasound and Csound can be good companions. I sometimes turn to
Csound for sample editing, like in creating samples, special FX or sample
based synthesis. Beyond that I only midified one isntrument though. If I ever
needed any kind of score, I typed it by hand using the csound score format.
Not really adviseable for real, old fashioned music, especially if it's
getting big (long or stacked voices high). :-)
Sorry, not to be of more help, but I just thought I'd throw in my two cents.
Kindest regards
Julien

Hi Alex,
I've cc'd this reply to the Csound devs list, perhaps someone there can
tell you more.
I agree that jackmidi in Csound would be a Very Nice Thing. :)

Julien, thanks for the heads up. Jackmidi would indeed be useful.
We're not all crusty old Alsa seq users anymore. :)
Regards,
Alex.

Dave, thanks for forwarding this. I'm so new at Csound and Blue that
i'll take some time to stumble around a bit with it first before the
wave of questions start. (Still trying to figure out how to add a
soundfont to a fluid instrument, and add an instrument in a score
track, to a polyobject or a genericscore object. The brain is melting.
:) )
Given the relative and elegant simplicity of jackmidi structure,
perhaps those much wiser than i about these things will have a fit of
enthusiasm, and consider implementing it, so we can all go forward
together. :)

unfortunately, this misses a much deeper aspect of the difference
between ALSA and JACK MIDI.
ALSA MIDI delivers MIDI (in all likelihood) to something other than
the thread doing synthesis/processing. This can be nice when using
MIDI for application control (transport, solo/mute/rec-enable etc etc)
but it makes it a bit more difficult to use it in the synthesis
thread.
JACK MIDI delivers MIDI to the thread doing synthesis/processing. This
makes it very easy (and accurate) to use MIDI for
synthesis/processing, but harder to use for application control (which
likely happens in another thread).
finally, JACK MIDI *only* allows MIDI output (directly) from the
processing thread, whereas doing that in ALSA is a recipe for xruns
etc and you really have to do MIDI output from some other thread.
so for example, switching Ardour from using ALSA MIDI to JACK MIDI
wasn't just about using a different API for getting MIDI in and out.
it required a substantive re-engineering of how all MIDI I/O is done.
