[Qmidiarp-devel] QMidiArp-0.4.5 released

From: Frank K. <goe...@ya...> - 2012-01-21 18:00:59

Hi there!

QMidiArp 0.4.5 is now available for download and contains two
bugfixes for issues reported on the IRC by quilzo.

http://sourceforge.net/projects/qmidiarp/files/qmidiarp/0.4.5/

qmidiarp-0.4.5 (2012-01-21)

Fixed Bugs
  o JACK Transport start with ALSA backend was broken in 0.4.4
  o Crash when events not matching any channel in any module were
 received in JACK MIDI backend


For those who want to check out some new features under development, the 
current "globalstore" git branch contains a new global parameter store handler 
allowing to switch all settings in one click at a defined time which can be very
handy in live situations. For this,

git clone git://qmidiarp.git.sourceforge.net/gitroot/qmidiarp/qmidiarp
cd qmidiarp
git checkout globalstore
autoreconf -i
./configure
make

Best

To all who have already grabbed the tarball 

before two hours ago, 

may I ask you to grab it again. Although the tarball worked, 

it contained one wrong source file producing debug output, which 

is not very clean.

Thanks to Nedko who has quickly seen this

Apologies....again

[Qmidiarp-devel] QMidiArp-0.4.4 released

From: Frank K. <goe...@ya...> - 2011-12-24 09:00:03

One month after the last one, QMidiArp 0.4.4 comes as a bugfix release,
and the only new 'feature' is that the JACK MIDI backend can run 
without JACK Transport too.

Everyone is encouraged to upgrade to this version available at

http://qmidiarp.sourceforge.net

With many thanks to the reporters (and christmas wishes of course :) )

[Qmidiarp-devel] Planned bugfix release

From: Frank K. <goe...@ya...> - 2011-12-20 19:42:33

Hi there,

due to the big bug crashing qmidiarp for some of you at startup I think the best 

would be a bugfix release soon. There are a couple of other small
issues that I have fixed since 0.4.3 in git, and if you find the time
please check out the current git version and let me know if it works
as expected. Don't hesitate to report also small issues and ideas
so that we can hopefully end the year with a proper qmidiarp
version. 


Have it a try,
best regards
Frank

[Qmidiarp-devel] QMidiArp-0.4.3 JACK MIDI patch

From: Frank K. <goe...@ya...> - 2011-12-05 21:57:49

Dear all,

as reported by some users, in certain cases QMidiArp-0.4.3 crashed with a floating point exception directly on startup when used with JACK MIDI. This exposed only on a few systems, at least one of them AVLinux (unfortunately not mine), but is still a big bug due to a missing initialization.

It is now fixed by a patch that can be found here:

http://sourceforge.net/projects/qmidiarp/files/qmidiarp/0.4.3/qmidiarp-0.4.3-fix-transport.patch/download


It is applied with

cd qmidiarp-0.4.3
patch -p1 < qmidiarp-0.4.3-fix-transport.patch


Thanks to the two reporters and Robi for the remote access to a system exposing the bug.

Hi Frank,

Thats good news - no problems building here in Fedora, just a couple of 
minor rpmlint warnings I've patched here for inclusion down the track.

One simple FSF address the second where a man page warning:
qmidiarp.x86_64: W: manual-page-warning

[Qmidiarp-devel] QMidiArp-0.4.3 released

From: Frank K. <goe...@ya...> - 2011-11-20 18:33:06

Here it is, a new QMidiArp version has arrived! The main new features are JACK MIDI, 

which is the default backend now, JACK Session support, and a new in-sequence loop 

marker that can be used to bounce the play direction or to loop at a mouse-clicked 

position in the sequence. Note that you can still get the alsa backend by starting with
qmidiarp -a .

The full list of noticeable changes is below.

Thanks again to all having reported ideas and bugs and given their support.


Masters of the step sequencer, Enjoy!

New Features
  o Groove functions now work for all modules, not only Arps
  o Effect of groove settings is displayed in the Arp/LFO/Seq screen
  o LFOs can be triggered and restarted by the keyboard
  o When reducing the size of LFO waves or Sequences, the original data
    is kept in memory and is also saved to the session file as a whole
  o LFO and Seq play direction can now be chosen, and bouncing loops are
    possible
  o New user positionable loop marker in Seq module. The marker is
    placed by left or right mouse click on the bottom cursor line of the
    sequencer and represents an additional return/loop point. It can be
    removed again by clicking in the bottom left or right area of the
    Seq screen.
  o Triggered one-shot play of LFO and Seqs improved
  o JACK MIDI backend available. This is now default, use the -a option
    for getting the ALSA backend
  o JACK Session support when using JACK MIDI backend

Fixed Bugs
  o A rounding error led to desync when Arps were used with groove shift
  o MIDI controls for Groove did not initialize upon "New..."
  o MIDI Controllers assigned to multiple destinations stopped at the
    first one encountered and ignored all others

General Changes
  o JACK MIDI is now the default backend, -a option enables ALSA backend
  o Obsolete .qma text file import removed

In addition to the play direction switch we now have an, no, THE in-sequence loop marker available.
This one is, I think, what Sascha suggested as a feature. 
You can place a loop marker using left or right mouse buttons on the bottom frame (where the cursor is).
The loop marker goes away again when clicking in the left or right bottom corners.
Suggestions to make this better are welcome.
There was also a fix regarding MIDI Clock Sync not starting upon the second time the
MIDI clock started. MIDI Clock sync anyway has still a lot of jitter on my machine, 
and I don't seem to get this tackled easily. 

See ya

Frank

OK this part seems to be fixed now, was not a drama after all, but I had missed testing it on my old 32bit machine...:)
However I cannot reproduce the other (connection) error, so If this affects others please tell.

Thanks Sascha

Thanks for your reports.

Hmmm, that is not what I expected. I tested it on two machines here, both running jack2 though and it ran flawlessly with Jack MIDI. I have a third (slower) machine available today and will test it there.
Is the first machine (where you get the "port not available" messages) running jack1? 

If there are machine-dependent errors that's a bad sign...

I hope we can this sorted and look forward to more info. I'll be around on IRC #qmidiarp, too.

Cheers
Frank

Hi Frank,

second test on another machine:
Archlinux: Kernel-rt 2.6.33
qjackctl 0.3.8
jack2 1.9.7-2

- builds fine.
- runs fine with alsa
- qmidiqarp -j works ... for a while ..
I see qmidiarp in Jack-Midi tab and if I press start on qjackctl qmidiarp
runs ... but not long ... qmidiarp stops playing after different times and
I get no error messages at all.
stop/restart jackplay runs qmidiarp but again it stops after a while
(sometimes 4 steps as a minimum and sometimes 2 loops as a max)

greetings, sascha

Re: [Qmidiarp-devel] More News from the git cuisine

From: Sascha S. <ung...@gm...> - 2011-11-04 11:38:20

Hi Frank,

tested the git and it builds perfect.
qmidiarp runs well with alsa but with the option "-j" I get:
# jack process callback registered
# float exception (original => Gleitkomma Ausnahme)
and the jack messages show something like:
# Output port index = 7 not found for application ref = 3

and a little cosmetic issue:
in the step-sequencer the "Display"-options could be a dropdown (Full,
Upper, Lower ....) that would save some height.

will test more this weekend

Greetings, Sascha

[Qmidiarp-devel] More News from the git cuisine

From: Frank K. <goe...@ya...> - 2011-11-03 22:49:44

Hi all,

just to give some more updates on the current qmidiarp git version (did I say that autumn..ah...phew..)
I have included some new features that might be interesting to some of you.
Here's the summary:

  o Groove functions now work for all modules, not only Arps
  o Effect of groove settings is displayed in the Arp/LFO/Seq screen
  o LFOs can be triggered and restarted by the keyboard
  o When reducing the size of LFO waves or Sequences, the original data
    is kept in memory and is also saved to the session file as a whole
  o LFO and Seq play direction can now be chosen, and bouncing loops are
    possible


If someone finds the time to test this and the program as a whole (don't forget to use -j option 

once in a while to get JACK MIDI) that'd be really helpful, the signs of a new release start 

appearing, and it could be somewhen in november if there is not too much mess with 

the current version.

Enjoy and let me know :)
Best

Frank

[Qmidiarp-devel] JACK MIDI progress

From: Frank K. <goe...@ya...> - 2011-08-28 12:53:30

Dear friends,

Summer is almost over, not much has happened around QMidiArp development.

Wait, there was one thing: JACK MIDI support. There is some progress on that end, and those
of you in need of a JACK MIDI interface for QMidiArp might want to checkout the jack-midi git
branch. As things stand, this is currently fully working, at least from my testing point of view.
Nothing has improved regarding input latency (which is two ticks now, about 20 ms), but at least
those having trouble with unstable ALSA timers might see an improvement over the ALSA driver.
To go beyond that, some more work and Nedko's (with who's help the architecture
changes up to now could be done) competences will be badly needed, since I still don't feel 

comfortable in real-time programming.


To get the test version do a git clone and checkout the jack-midi branch:

git clone git://qmidiarp.git.sourceforge.net/gitroot/qmidiarp/qmidiarp 

cd qmidiarp
git checkout jack-midi
autoreconf -i
./configure
make
sudo make install

you can now call qmidiarp with 

qmidiarp -j 


to use the JACK MIDI backend, otherwise the alsa backend is used as before.

You'll need a transport master such as qjackctl or qtractor aside to start qmidiarp in JACK mode.

I'd like to know whether it works for you as well as it does here. I must say I use an rt-kernel and a 128ms jack period. No xruns.


Have fun, and let me know whether it does as it should, also, does the old ALSA interface still work as before?


Cheers
Frank
