Hi,
Can someone point me to a very simple and obvious HOWTO on making OSC work
with Linux Apps?

From a developer's perspective, I found liblo to be
a good wrapper
around OSC. Here's a snip from the liblo README:
-----------------------
liblo is a lightweight library that provides an easy to use implementation of
the OSC protocol. For more information about the OSC protocol, please see:
- http://www.cnmat.berkeley.edu/OpenSoundControl/
- http://www.opensoundcontrol.org/
The official liblo homepage is here:
- http://liblo.sourceforge.net/
-----------------------
I do most of my development in Python, but I found the "pyliblo"
bindings for liblo to be Good Enough (tm) to get my app responding to
and generating OSC. I did have to make a small patch or two which I
haven't submitted back upstream; if you are using the Python bindings
let me know and I'll point you to my changes.
It was quite a nice feeling to click "Learn", wiggle a fader on my
iphone TouchOSC app, and watch the fader in my Linux app start to move!
Thanks,
Bill Gribble

I might need that shortly.

How does one achieve that set of steps with Linux software? Is there a
generic OSC control app for Linux that will communicate with any OSC
enabled app?

The way I implemented learning is to add a default handler to my created
OSC server, take the next incoming message, pick the "path" out of it,
and then add a handler for THAT in place of the default. It's possible
to get in a race if you are trying to learn with lots of OSC data flying
around but that's the user's issue :)
I think OSC was designed with the idea that the servers would define the
"name space" of paths and you would build a client map to send controls
to the proper destination. It looks more like it's really working the
other direction, where the clients/controllers define the paths they are
going to send, and the server is responsible for learning the mappings.

The reason I'm asking is for controlling jamin remotely. JAMin already has
OSC functionality after all Steve Harris wrote liblo ;-)
My problem is figuring out how to test JAMin to make sure I haven't broken
anything with any of my recent updates. Specifically I added a "Daemon" or
"Headless" mode and I would like to check that the controls are all still
working. In addition it would be nice to be able to control the JAMin
daemon from a remote machine. So the the two issues are how to connect to
a server app and also how to do that from a remote machine.
it looks like oscsend is going to be the way to go for now.
I'm tempted to spend some time on a python/clutter generic osc controller
app but if you have already started on that it might not be necessary. I'm
also thinking of adding support for OSC send to JAMin (if it is not
already there) so it can be a remote controller for the JAMin daemon. Call
it "controller" mode...

Otherwise you have to write a little user interface that dispatches
the OSC commands with arguments to tickle the corresponding functions
in JAMin.
If you want a bit of a GUI you'll make up creating
a bunch of widgets for each type of control.
In other words, sounds to me like duplicating a lot of what Jamin
already does.
I'm also considering adding OSC control to Nama although I'm
a little peevish as Nama users already has a protocol for
remote control: ssh! With ssh -X I even had the Tk GUI
running remotely. I recall there is a protocol to compress X
network traffic as well.
If I do implement OSC control for Nama, it should map fairly
directly to Nama's existing command language, so the
language parser will to dispatch the command inputs I get in
the OSC format over the socket. It might be nice if
something could be made to work with a short hack. :-)

A generic solution would be a slider/knob and button that could be
arranged in any order/number and associated with any control value.
Then users can build their own control modules.
I'll have to check out the python module Bill mentioned first to see how
much effort is required on my part before committing to it though.
I'm not sure how to get a remote JAMin controller to find the daemon
server. If it is just a case of assigning the ip address and port number
then that should be pretty easy to implement. Just a case of adding send
commands to each control widget then.

Just as an aside: There's also vncservers and viewers which do not need
a persistent connection..
