I don't think so..
tu run "tuxguitar-alsa" you need first ALSA (Advanced Linux Sound Architecture) libraries installed in your system.
but Alsa is only available for linux.. ( isn't it ? )

You can't.
It should however be possible to build a CoreAudio plugin and use the native instruments - there just needs someone to make it.
I think I have enough CoreAudio knowledg to make it, but not enough tuxguitar knowledge. perhaps if Julian points me in the right direction? (Basically it's easy to fill noteOn/noteOff/programChange/controlChange/picthBend stuff, there just isn't any notion of device and ports on mac)

Well my wording was bad - there are devices but for plain playback you don't need to care about them.

sp there is no way to improve the tux guitar sound bank? and in the next version can't you just make a soundbank people use on ALSA standard?

Hi,
To Auria:
>It should however be possible to build a CoreAudio plugin
>and use the native instrument
yes it's possible..
everyone can take the TuxGuitar-alsa project, and override
only the native methods ( *.c )
but i can't do that because i don't have a mac
To Jeremy:
>sp there is no way to improve the tux guitar sound bank?
TuxGuitar is not a software synthesizer.. it only connect to it.
as default, because it's written in java, it uses the "Java Sound Api" .. and Java Sound Api, is who needs the "soundbank" file.
however CVS version ot tuxguitar, has better options to select a midi device.. it works better under windows, because java sound api can see native ports under windows (i didn't know that )..
i tell you this, because maybe it also can see native Mac ports (i can't know)..
>and in the next version can't you just make a soundbank
>people use on ALSA standard?
i can't understand this question. (my english not good)
Alsa is the Linux Sound library..
tuxguitar-alsa plugin, is only to connect tuxguitar with alsa.. and select a native Midi Port.
that Midi Port. (sytnhesizer) is who play the sounds..
so a tuxguitar "soundbank" is not needed.

yes i know
My question is, I suppose the Alsa plugin deals with ports somehow, and there is no need for such concept on mac, so i'm not sure how Alsa plugin lets the user choose a port and what I should change to change this behaviour.
[quote]sp there is no way to improve the tux guitar sound bank?[/quote]
Yes there is i'm discussing it right now with Julian... But forget Alsa, Alsa is Linux. You need to either a) get a better Java soundbank b) use a CoreAudio plugin to use Quicktime instruments (the plugin does not exist but I might be able to make it)

well, i don't have any idea about mac..
i can tell you only how to make an output plugin for tuxguitar (under CVS version):
it are bassically 3 java interfaces:
---------------------------------------------------
MidiPortReader: it has only 2 methods:
*listPorts: returns a list of MidiPorts
*closeAll: close all ports.. (called at the end of the app)
maybe this method should be renamed to "free"
MidiPort: it contents the port info..
*getName: a single name to show at "selection" combo
*getKey: a unique key for that port. (needed to open it later)
*open,close: don't need explication.
*out: it returns the MidiOut for that port. (previously opened)
MidiOut: here are the midi events:
sendSystemReset();
sendAllNotesOff();
sendNoteOn(int channel, int key, int velocity);
sendNoteOff(int channel, int key, int velocity);
sendProgramChange(int channel, int value);
sendControlChange(int channel, int controller, int value);
sendPitchBend(int channel, int value)
---------------------------------------------------
so.. thats all.. tuxguitar do the other.

i forget say:
to get plugin work.. this file should be at classpath:
META-INF/services/org.herac.tuxguitar.player.base.MidiPortReader
and the content of that file should be:
package.bla.bla.MidiPortReaderImplementation
then tuxguitar will take dynamically it at start.
remember.. all of this works only on CVS version.

>i didn't think i needed CVS version for this
well, there are a lot of changes in CVS version..
1 of them is the combo to select a midi device at
"config -> sound"
to build it:
first type:
ant -Ddist.version=version
it'll made an TuxGuitar-[version]-src.tar.gz
it bassically makes a source package exluding non necessary files from CVS version.. and put the content of xml/* at first directory level.
then you need extract that source package,
modify "build.properties":
uncomment all at your OS settings. and comment the others.
also, see for swt.jar.. as default this is the path:
lib.swt.jar=lib/swt.jar
but that jar is not included at CVS version.. so you should download it: http://www.eclipse.org/swt
and type "ant" again.
if you select the mac settings, it will create an "tuxguitar-[version]-mac.app"
you can make a .dmg file following this:
http://www.eclipse.org/swt/macosx/

"org.herac.tuxguitar.player.base"
is at TuxGuitar project..
Are you building a plugin ??
if you are doing it..
you should build it also with "ant"..
but you need edit build.properties.. and set:
path.tuxguitar=here_the_path_of_tuxguitar.jar
OR
path.tuxguitar=here_the_path_of_tuxguitar src/
path.swt==here_the_path_of_swt.jar
Note, if you set the path of tuxguitar sources, swt.jar is needed.
remember, plugins and serverces. must be from CVS version.
also, i think you are tring to build tuxguitar-alsa ???
it'll fail on the try.. because it try to build native ( C ) sources.
however.. onces builded, you should move the tuxguitar-[plugin].jar to:
TuxGuitar/share/plugins
Or
TuxGuitar/share/services
(note tuxguitar-alsa, is not a plugin anymore.. it is now at services folder)
tell me.. did you try this version, already can load native devices ?? at "config -> sound" (it can't under linux.. but yes under windows)

[quote]it'll fail on the try.. because it try to build native ( C ) sources.[/quote]
No, I modified the Alsa sources to remove Alsa code. Now i'm just trying to compile.
Now I have a "tuxguitar-coreaudio.jar" file, thanks! I put it in services folder, but how can I get tuxguitar to use it now? you said "
to get plugin work.. this file should be at classpath:
META-INF/services/org.herac.tuxguitar.player.base.MidiPortReader" but i can't find that file - do i need to create it?

Ok,
you have your own plugin "tuxguitar-coreaudio.jar"..
>META-INF/services/org.herac.tuxguitar.player.base.MidiPortReader
>but i can't find that file - do i need to create it?
yes you need..
i'll try explain you (with my bad english)
TuxGuitar, has a class to load that service|plugins:
TGServiceReader.lookupProviders(Class c);
the lookupproviders method, try found all files called:
META-INF/services/[Class.getName()]
and make an Iterator with the content of the files.
on this case, the method is called as:
lookupProviders(MidiPortReader.class)
and the content of:
META-INF/services/org.herac.tuxguitar.player.base.MidiPortReader
should be the "package + classname" of the class what implements "MidiPortReader".
Note, all services included it on the jar file.. (see at build.xml of any plugin how they do that)
but you can put it at share/META-INF folder to test.

right now the META-INF/services/org.herac.tuxguitar.player.base.MidiPortReader file contains "org.herac.tuxguitar.player.impl.midiport.coreaudio.MidiPortReaderCA"

Thats seems to be right..
now, copy that jar to "tuxguitar/share/services"
and run tuxguitar..
go to "Settings -> Configure" and at "sound" tag, you should see the generated midi ports at the "Midi Port" combo.
one thing... at "share/services" remove "tuxguitar-alsa.jar" if it exists because it can crash...
the other "tuxguitar-jsa.jar" (is the Java Sound Api implementation).. so you can also remove it.. if you don't want see "Java Sound Synthyesizer" port.

mmm we posted at same time...
about: "java.lang.UnsatisfiedLinkError"
first.. if you get that error.. is because tuxguitar could see the service.. so thats good.
well that error, is because the plugin is trying to load a Native library "tuxguitar-coreaudio-jni" and not found it.
i'm not sure what was the maded changes.. so i aks you some things:
**Are you using native sources ( *.c or *.cpp)???
if you aren't, you should remove:
---------------------------------------------------
static{
JNILibraryLoader.loadLibrary(JNI_LIBRARY_NAME);
}
---------------------------------------------------
from MidiReceiverJNI ?? (thats the class on tuxgutar-alsa)
if the answer is yes..
did you build the native library ???
the library should be at LibraryPath, to java found it..
-Djava.library.path= (look at tuxguitar launcher script)
Or, you can do equal as tuxguitar-alsa.. it includes the native library on the jar..
and "JNILibraryLoader" load that library.

My code is just a modification of the Alsa code, so it works the same way.
it produces a .jnilib that gets included inside the jar file. the biggest modification is that i changed it to C++ however the header defines it as extern "C" so it still has C linking and there shouldn't be problems
I think the error could be that the "-shared" g++ switch does not exist on OS X so I built a dynamic lib instead of a shared lib.

It should work as dynamic lib too.
I think you should forget about JNILibraryLoader for the moment, as this class was created having in mind the linux library.. It may not work on mac.
Instead use java framework to load the dynamic library:
----
* System.load(String filename)
Loads a code file with the specified filename from the local file system as a dynamic library.
* System.loadLibrary(String libname)
Loads the system library specified by the libname argument.
----
The first one, takes as argument the filename of the library, for instance, System.load("/home/xx/mylibrary.so") would load the library with that name.
The second one, uses the O.S. convention to load the library.. for instance, on linux System.loadLibrary("test") would load the library named /lib/libtest.so while on windows would load c:windowstest.dll ...
System.loadLibrary() looks for libraries on the java.library.path, you can set this using -Djava.library.path=xxxx on the command line (tuxguitar's launcher script sets this option).
On some systems, the folder where the library resides needs to be on LD_LIBRARY_PATH.
If none of these work properly, you should take a look at some documentation on how to do jni on mac.

A few questions i don't get...
1) when you play a song then press stop, note off events are not thrown so the note continues to play forever. how does TG tell the player to stop all sound?
2) what is jint note? when i play using this as midi key, the played pitch is wrong... any idea why this happens?

Hi,
>how does TG tell the player to stop all sound?
On this order, that methods of MidiOut are called by the sequencer:
sendAllNotesOff();
sendSystemReset();
>what is jint note? when i play using this as midi key, the played pitch is wrong.
I'm not sure if i understand the question...
but however..
note there are differences of pitch value, with tuxguitar-alsa and tuxguitar-jsa:
at the method "sendPitchBend(int channel,int value)"
tuxguitar-alsa uses pitch as: ((value * 127) - 8191)
but on java sound API "value" not need be changed.
so, maybe you should see if it need be changed or not for coreaudio.

@Jeremy : Sorry for hijacking your thread! there is no other java soundbank that i know of. I know there is a commercial tool to create custom ones but i don't know much more.
@Julain: ok thanks first problem fixed.
my other problem is not with pitch bend.
I will give you an example. I will use fret 0 on highest string, which is a E note and midi key 64. When I add such note, my plugin receives a request for 'note on 64' message.
Then i choose "Play". I still receive a note on 64 event, but the pitch is not E, it is much lower than that.
It seems to be a pitch bend or a controller problem, I will inverstigate.

Ok i found the problem : it is controllers 100 and 101 (Registered Parameter Number LSB and MSB)
I don't know what these controllers are used for, i however was able to solve pitch problems by blocking them. I'm not sure sure why the change the pitch of played notes.
Now all that remains to fix is pitch bend and we can have native playback on mac.

Hi,
>Ok i found the problem : it is controllers 100 and 101 .....
That controllers are needed to set pitch bends greater than 2 semitones.. (for effects: bend, slide...).
i don't know exactly what they do...
but if they aren't setted, the pitch bend don't work fine.. (a slide from 2 TO 10, make sound as "2 TO 4")...
i taked that controllers, watching "midi" files what could play that pitch bends..
i think.. you can test export a midi file with tuxguitar, and listen it on a midiplayer.. and if it works, that shouldn't be the problem.. maybe something like "value * anyNumber" can be a solution.
>would you like to host it along alsa plugin, or?
well that's your decition.. "it's your project".
ofcourse you are welcome to upload it to the CVS and it will be included on Mac version. and ofcourse you at authors section.
Or you can register it on a new project. (on this case, it will be included if license is "compat" with tuxguitar license)
let me know, by "Contact" mail..

easiest is to wait for next version to come out. or you can build it yourself. or i also have it on my computer i could send it to you (though be aware CVS versions are not necessarly stable)

How hard would it be to make it work with MIDI output ports so that TuxGuitar could play on external Midi synths? (or soft-synths by using MidiPatchBay)
I'm doing a soft synth for the Mac and I would like to be able to use it with TuxGuitar.

Hi, i never had a mac.. so i'm "blind" to answer this questions.
It's supposed, you have the "CoreAudio" plugin maded by Auria.
I'm not sure how to connect to an "external synths" on mac, and if CoreAudio can do this.
but however, since 1.0-rc1 "all" tuxguitar ports/sequencers are "plugins". ( if you drop the folder share/plugins of tuxguitar, it'll not sound anymore ).
So if you already have your MIDI Synth (written on Java or C/C++ ) it's very easy to make a tuxguitar plugin
You'll need just a wrapper class beetween tuxguitar and your synth..
with methods like:
sendNoteOn( ... ), sendNoteOff( ... ), sendControlChange( ... ) bla bla bla.....
