Title: First release: LinuxBand 12.02 Beta
Post by: noseka1 on February 12, 2012, 08:33:09 PM
Hi all,
just to introduce myself. I'm a developer mainly in C++ and Java on Linux platform. In my free time I like to play jazz guitar. To accompany my improvisation practicing I has been using MIDI files generated by MMA. To facilitate writing of MMA files and playing them back I created LinuxBand. I hope you'll enjoy it.
Ales
LinuxBand is a GUI front-end for MMA (Musical MIDI Accompaniment). Type in the chords, choose the groove and LinuxBand will play a musical accompaniment for you.
It’s an open source alternative to Band-in-a-Box featuring:
Easy to use graphical interface
Open and well-documented data format
Output to JACK Midi to facilitate co-operation with other audio applications

Okay, this is completely out of the blue! I'll have to look at it later. Looks like a very cool project.
Guess, this will be similar to lemma (I ask having not tried it out yet)?

I think I've been away from C for too long :) I did a clean ./configure but make really complains: bob$ make cc -o target/linuxband-player -I/usr/include/glib-2.0 -I/usr/lib/i386-linux-gnu/glib-2.0/include -pthread -I/usr/include/glib-2.0 -I/usr/lib/i386-linux-gnu/glib-2.0/include -I/usr/include/glib-2.0 -I/usr/lib/i386-linux-gnu/glib-2.0/include -I. -lglib-2.0 -pthread -lgthread-2.0 -lrt -lglib-2.0 -ljack -lsmf -lm -lglib-2.0 src/main/c/linuxband-player.c src/main/c/midi.c src/main/c/remote_control.c /tmp/ccjGvEFC.o: In function `warning_async': linuxband-player.c:(.text+0x110): undefined reference to `g_log' /tmp/ccjGvEFC.o: In function `warn_from_jack_thread_context': linuxband-player.c:(.text+0x130): undefined reference to `g_idle_add' /tmp/ccjGvEFC.o: In function `nframes_to_ms': linuxband-player.c:(.text+0x145): undefined reference to `jack_get_sample_rate' /tmp/ccjGvEFC.o: In function `ms_to_nframes': <and lots more> I suspect I'm missing yet-another-dev-library.

After successful ./configure the compilation should not fail. I'll have to fix it.
However, your compilation line seems very similar to my:
cc -o target/linuxband-player -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I. -lglib-2.0 -pthread -lgthread-2.0 -lrt -lglib-2.0 -ljack -lpthread -lrt -lsmf -lm -lglib-2.0 src/main/c/linuxband-player.c src/main/c/midi.c src/main/c/remote_control.c
And the required symbols are in those libraries:
nm -D /lib/libglib-2.0.so.0 | grep g_log
000000000004dc40 T g_log
As I see i386-linux-gnu directories in your output. Can't it be that for some reason you compile for 32-bit arch but try to link against 64-bit libs, or the other way round?

I don't have any 64 bit stuff on the machine.
This is Ubuntu 11.10.
I think I have the needed "dev" packages. If not, it should be found in the configure.
Isn't g_log a macro? So it should be defined in a header file? Could that be missing?
But, if I look for the g_log you are using:
[03:07 PM /usr/include/glib-2.0] bob$ grep -ir g_log_set_default_handle *
glib/gmessages.h:GLogFunc g_log_set_default_handler (GLogFunc log_func,
So, that one (and I assume the others) are there.
Let me log in/out and try again.

Okay, I' lost :)
I double checked the dep list:
apt-get install libjack-dev
apt-get install libsmf-dev
apt-get install python-gtk2
apt-get install python-gtksourceview2
All were okay, except that the first line deleted my existing libjack2 stuff and installed libjack1.
No differences in the compile. Next?

Now, let's check that your linker is linking against correct libraries. On my machine -lglib-2.0 would cause linking the /lib/libglib-2.0.so.0.2800.8 library file because the symbolic link /lib/libglib-2.0.so.0 points to it.
So I replace all occurences of -lglib-2.0 with /lib/libglib-2.0.so.0.2800.8 and try the resulting compilation command:
cc -o target/linuxband-player -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I. /lib/libglib-2.0.so.0.2800.8 -pthread -lgthread-2.0 -lrt /lib/libglib-2.0.so.0.2800.8 -ljack -lpthread -lrt -lsmf -lm /lib/libglib-2.0.so.0.2800.8 src/main/c/linuxband-player.c src/main/c/midi.c src/main/c/remote_control.c
This way, the linuxband-player.c:(.text+0x110): undefined reference to `g_log' error should disappear because the symbol is there as checked using grep before.

I needed to change your example cc line to: cc -o target/linuxband-player -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/glib-2.0 -I/usr/lib/i386-linux-gnu/glib-2.0/include -I/usr/lib/glib-2.0/include -I. /lib/i386-linux-gnu/libglib-2.0.so.0 -pthread -lgthread-2.0 -lrt /lib/i386-linux-gnu/libglib-2.0.so.0 -ljack -lpthread -lrt -lsmf -lm /lib/i386-linux-gnu/libglib-2.0.so.0 src/main/c/linuxband-player.c src/main/c/midi.c src/main/c/remote_control.c But, that gives the same errors as before :) /tmp/ccGhZH7T.o: In function `warning_async':

Finally, here is the fix for the compilation problem. Apply the attached patch and make again:

That fixed it ... reminds me why I don't miss programming in C :)
But, there seems to be a problem with linuxband finding my lib, etc. I have a link /usr/local/share/mma which points to my main mma tree and mma in /usr/local/bin.
Yes, I did a make install on linuxband.
The last few lines it prints to the terminal might help:
Traceback (most recent call last):
File "/usr/local/share/linuxband/linuxband/midi/mma2smf.py", line 38, in check_mma_syntax
mma = subprocess.Popen(command, stdin=subprocess.PIPE, stdout=subprocess.PIPE)

I suspect a path issue?

:D ;D I could compile your program (I run Ubuntu 10.10 - 64 bits). Looks good! A few points, though: - It looks very much like Lemma => http://welltemperedstudio.wordpress.com/code/lemma/ (http://welltemperedstudio.wordpress.com/code/lemma/).
- I think the name (LinuxBand) and the choice of Jackd makes it to restrictive. It should run on Windows, too.
- I'd appreciate Alsa or/and Pulse Audio support. Beginners can't easily setup Jackd.
- We definitively need a graphical groove editor. It would make MMA less daunting for newbies (Yes Bob, I know: with a UI, one can't exploit all the power of MMA. However,...). To be considered for next versions.
Thanks. Alexis

I've always been of the opinion that my time is best spent in worrying about the parser and the file creation bits of mma. And it is trivial (yeah, right) to add a gui front end to the program. So, I really do welcome programs like linuxband! Let's get more people using mma ... which, I keep hoping, will lead to better libraries and better sounding backing tracks.

- We definitively need a graphical groove editor. It would make MMA less daunting for newbies (Yes Bob, I know: with a UI, one can't exploit all the power of MMA. However,...). To be considered for next versions.
Ahh, but you forget that there has always been a GUI for mma. It's called emacs :)

You can set path to MMA in View/Settings (or Preferences). Default is /usr/bin/mma.

Okay, a few little things:
1. The preferences is not working as it should. Clicking, for example, on <groove dir> brings up a short list of directories, but I cannot step though a selected dir. I'm only able to select a top level entry.
2. I can edit the .linuxband/linuxband.rc file and change the paths there.
3. I think there is a concept problem with swingmode. You're not the first to have this problem ... but the way you are using it (just like in lemma) it has no effect. The loading of a groove restores the previous setting. Doing it after a groove is loaded doesn't help either since the sequences are already parsed. For a user, the only time swingmode has an effect is when you have something like: Swingmode On ... some solo notes .... I think this is covered in the docs, but I'll re-read them before the next release.
4. Not sure how you are doing the "follow the bouncing ball" thing to highlight the chord changes. But, I might be able to help at this end by writing data to follow into the meta track of the midi.
5. With jack running I get no sounds playing a midi track. Player issue? Jack not setup right? I don't know since I normally don't run jack.
...........
If I send more time on this I'm sure I can help more.
It's a great concept and should help folk who, unlike me, don't love the command line :) Look forward to the next version!
Best,

A few points, though: - It looks very much like Lemma => http://welltemperedstudio.wordpress.com/code/lemma/ (http://welltemperedstudio.wordpress.com/code/lemma/).
- I think the name (LinuxBand) and the choice of Jackd makes it to restrictive. It should run on Windows, too.
- I'd appreciate Alsa or/and Pulse Audio support. Beginners can't easily setup Jackd.
- We definitively need a graphical groove editor. It would make MMA less daunting for newbies (Yes Bob, I know: with a UI, one can't exploit all the power of MMA. However,...). To be considered for next versions.
Thank you for your comments. I chose the name LinuxBand to promote my favourite OS and to indicate that LinuxBand is targeted on the Linux platform. Yes, Alsa support would make it easier for beginners to enter. Also groove editor would be nice to have. Patches are welcome.

Thank you for testing! 1. The last item in the list is "Other ..." Here you can step through dirs. This is a standard GTK dialog. I find it not too well done. 3. Well, I set that Swingmode by intuition. I should really look at the documentation. 4. That's the way I do it. 5. I cannot describe configuring Jack in two sentences, but there enough examples on the web.

Yeah, did that :) Didn't work either :)
