[linux-audio-user] [ANN] eisenkraut 0.3

[Jens Gulden]

Hello,

>> http://sourceforge.net/projects/eisenkraut

A sample-editor written in Java & SuperCollider is a great idea. Thanks, 
Sciss, for starting this!

I'm trying to get Eisenkraut running on Linux. These are the steps I 
have taken so far:

1) Added "libraries/NetUtil.jar" to the $CLASSPATH in Eisenkraut.sh
(otherwise a "java.lang.NoClassDefFoundError: de/sciss/net/OSCListener" 
occurs)

2) Needed to make a change in createTempFile() in IOUtil.class:
Instead of:
File tmpF = File.createTempFile( prefix, suffix, new File( 
IOUtil.getUserPrefs().get( IOUtil.KEY_TEMPDIR, null ) ) );
it's now just:
File tmpF = File.createTempFile( prefix, suffix, null );
It seems that
IOUtil.getUserPrefs().get( IOUtil.KEY_TEMPDIR, null )
returns null, which causes the constructor of java.io.File to fail. 
Luckily it is easy to work around this by just specifying 'null' as 
default directory for createTempFile(...), which causes the system's 
default temp-dir to be used.
(I wonder why this doesn't work with the value from the preferences. The 
saved preferences in ~/.java/.userPrefs/de/sciss/eisenkraut/prefs.xml 
correctly contain a 'tmpdir' value.)

3) In order to apply the above fix, I needed to recompile the project on 
my own, which in turn made it necessary to:
a) Change source file names in  de/sciss/eisenkraut/session:
__SessionChangeEvent.java to SessionChangeevent.java
__SessionChangeListener to SessionChangeListener.java
(Why are there underscores in the original filenames?)
b)Create a dummy-interface with an inner dummy-interface:
de.sciss.eisenkraut.realtime.RealtimeProducer and
de.sciss.eisenkraut.realtime.RealtimeProducer.Request.
(Sources for that are not included.)

4) A problem which is related to my specific configuration:
InetAddress.getLocalHost() seems to perform a lookup at the name-server 
to determine the current local ip-number based on the name of the host. 
But when I'm not in the office, my machine's ip number is different from 
what the hostname is associated to.
This led to the situation that the UDP packages were sent from the 
correct local ip address to a wrong/non-existent address in the outside 
network (that was returned by getLocalHost()).
One could blame either my "hand-made" multi-ip-configuration, or Sun's 
implementation of getLocalHost() for the problems that occurred from that.
But in any case it would be very useful to be able to avoid problems of 
this kind by letting the ip-part in the preferences-field "Supercollider 
OSC Socket (IP:port)" also take effect.


After solving these above issues, I am stuck. Eisenkraut now starts up 
properly and it boots the SuperCollider server upon manual request 
(Boot-button). It also loads a sample-file via File/Open..., and when 
pressing 'play' in the transport window it displays a red time-indicator 
moving above the waveform.

...But there is no sound coming out of my speakers...

My SuperCollider installation is working fine when used with the 
SC-language from inside Emacs, so I assume the problem is related to 
Eisenkraut and its interaction with the SC-server.
This is an example OSC-dump:

### (JENS): the next 2 lines also appear when I run SuperCollider from 
sclang within Emacs, so they seem 'normal' to me. Are they?

[assert] error: 111 (Connection refused)
[assert] where: "socket.c", "sw_socket_tcp_connect", line: 720

### (JENS): the next line is output by the time I manually connect 
SuperCollider's Jack-output to the alsa_pcm Jack-input with qjackctl:

SC_JackDriver: max output latency 0.046440

### (JENS): the following stuff appears when trying to play the sample 
(trying multiple times):

I don't see any error messages among these which could give me a hint of 
where to look next...

My versions are:
Eisenkraut 0.3.1
SuperCollider from CVS, 2005-05-29
Alsa 1.0.4rc2, Jacks 0.99.0, qjackctl 0.2.15a (all from Debian-sarge)
Sun-JDK 1.4.2_02
Kernel 2.6.6

See also a screenshot on 
http://user.cs.tu-berlin.de/~jgulden/test/eisenkraut-screenshot1.png

It would be great to have Eisenkraut working on my machine, so thanks in 
advance for help.

I hope this "herb" (Kraut) will grow and prosper well...

Jens
