I've been stumped for a while as to why my Tascam US-122 box stopped
working as a writeable midi port.
Using Debian Wheezy, everything was working up to a few weeks ago. MIDI
input still works and there's nothing suspicious in the /var/logs.
But...
nick@arial:~$ aplaymidi -l
Port Client name Port name
14:0 Midi Through Midi Through Port-0
20:0 TASCAM US-X2Y TASCAM US-X2Y MIDI 1
24:0 USB MIDI keyboard USB MIDI keyboard MIDI 1
nick@arial:~$ aplaymidi -p 20:0 Desktop/076903b_.mid
Cannot connect to port 20:0 - Input/output error
nick@arial:~$ uname -a
Linux arial 3.2.0-4-686-pae #1 SMP Debian 3.2.32-1 i686 GNU/Linux
Using older kernels doesn't help. Connecting e.g. rosegarden to the
TASCAM US-122 in qjackctl fails silently (the link is not made in the
connections window and nothing is printed on the console). Can't see
any module loading issues.
Is anybody else seeing this behaviour? I'd submit a bug report but
really can't figure out exactly what isn't working :(

We are proud to announce the release of guitarix2-0.24.3.
Guitarix is a modular mono tube amplifier simulation for jack, with
additional mono/stereo effect racks which can be filled with in-build
effect plug-ins as well as with external LADSPA plug-ins.
Presets can be stored for single effects and complete rack settings.
All UI controllers could connected over jack midi via MIDI learn with
your external MIDI controllers.
Guitarix works on LINUX, FreeBSD, and MAC OSX
Installer (binary) package for MAC OSX is available here:
http://sourceforge.net/projects/guitarix/files/OSX/
This release comes with the following changes:
* fix new unsaved banks return no valid iter (GTK warning)
* add new nice dark-style rc-file
Guitarix is licensed under the GPL
Please refer to our project page for more information:

have fun

I don't quite understand what you do... Is Ctl-Alt-- and Ctrl-Alt-+ a
way
to access Keypad+ and Keypad-? (To change editor font size)
(You can also use F5/F6 to change font size)
Also, when you talk about the window going over the screen boundaries
when
changing font size, is it the system font size you are changing then?
(You
can set the system font size in ~/.radium/config). Because the window
size
should not increase if you change the editor font size.
You can also press Left Ctrl + m to automatically fit all tracks in the
visible area. Left Ctrl + m makes radium use two characters for
note names instead of three. Left Ctrl + t changes the note names into
a
visual representation instead of text.

I agree about that. I think the main problem is horizontal space, so
possible having one key that changes between only showing the editor
or only showing the mixer would work. Turning on/off the instrument
window
isn't that important.
Radium is an open source music editor with a novel interface.
It's inspired by trackers, but has fewer limitations and uses graphics
to show musical data.

Thank you!
It seems like floorf crashes on your machine. (although I'm not
entirely sure the line number is correct since it was compiled with
-O3)
Which CPU do you have?
And why does this happen?
Radium is compiled with "-O3 -mtune=generic -msse"
Shouldn't that make it run on all CPUs that have sse instructions?

Hello all,
I'm working on a little app utilizing 'lasound' and I've got bassically
what I want. However, somewhere there is a fault. Editing a random
variable causes a segmentation fault. I've tried gdb but except it
telling me where the application crashed (which I already knew) I did
not get anything useful out of it. To minimize my own potential errors I
have here below the example script from where I started (though I have
removed some unnecessary stuff) and commented out the 'long *outvl' and
'*outvl = -1'. Uncommenting, compile, and run this and I get a
segmentation fault.
The original script is available at the following link:
http://stackoverflow.com/questions/7657624/get-master-sound-volume-in-c-in-…
Can someone tell me where this is going wrong?
Thanks in advance, Maarten

Good point about the driver
Unfortunately i couldnt find any info at all about this device (probably
because its cheap, new and built by a rather unknown company) and exactly
for this reason i would liks to share what i have found out

there is a reason why MIDI is a standard protocol.
the only way that a MIDI device is not Linux compatible is if it doesn't
actually send MIDI, but instead uses some proprietary protocol which is
then converted by a device driver into MIDI that can be seen by apps on the
computer.
there are very few such devices. the question to ask is whether it has its
own device driver - if it does not, then its about 99.78% certain that it
will work on Linux or with any other MIDI capable platform/device.
A wild crosspost appears!
Laborejo, Esperanto for "Workshop", is used to craft music through notation.
It is a Lilypond GUI frontend, a MIDI creator and finally a tool collection to inspire and help you compose.
It works by reducing music-redundancy and by seperating layout and data.
Before you read the details make sure to connect to Laborejos Facebook, Twitter or Google Plus!

This is the release of version 0.4
Download: https://github.com/nilsgey/Laborejo/tarball/0.4
Dependencies: http://www.laborejo.org/documentation
Linux Instructions: Unpack, cd into the created directoy, execute:
./laborejo-qt
Then use the number- and cursor keys for immediate success!
Check Help->Manual for navigational and note/rest entry keys. Everything else is in the menus.
New since version 0.3 (highlights):
* Lyrics are visible under the tracks directly and aligned to their notes
* Nicer cursor :)
* New dynamics like fp and sfz.
* New commandset for note speed entry with the numblock.
* Colored always-visible Marker in the GUI to indicate track groups. Also displays small instrument name for better orientation
* Lilypond binary and pdf viewer are now a config variable
* More Subsitutions (assign a pre-defined group to host notes. Group gets transposed and scaled accordingly). Final Fantasy arpeggio, common melody figures etc.
* Many bugfixes and small improvements that make the program work like you expected it to do anyway
Most important known problems:
* This is Alpha Grade Software. Don't use for long-term work. However, the produced midis and PDFs will last forever.
* There is no built-in jack midi output yet. You have to export midi files.
* Documentation is nearly non-existent.
* Deleting selected objects may result in strange gui behaviour. Nothing a save/reload can't fix for now.
Have fun, it would be nice to hear from you!
