I've compiled from the UX2 branch, but I cannot see any "PCM Capture
Source" control in alsamixer nor in gnome-alsamixer, Although "PCM" and
"Monitor" sliders are there.

Btw, device name is not present in gnome-alsamixer, just an empty tab. I
attach a screenshot.

The TonePort transmits the same signal on the left and right channels, but 
with largely different amplification. So if you hear a noisy signal in the 
right channel, try to move the balance entirely to the left side, where you 
might have the clear signal, which simply could not have been heard while the 
right channel was active. You can also use the monitor control in a mixer 
application to adjust the volume of the guitar signal.

I just added support for source select on the UX2 under the assumption that 
it's identical as on the UX1 in the following subversion branch:

https://line6linux.svn.sourceforge.net/svnroot/line6linux/driver/branches/ux2

Please also have a look at

http://sourceforge.net/projects/line6linux/forums/forum/713265/topic/3695415

which is the discussion with an UX1 user finally leading to some of UX1's 
features being supported. Can you please provide the list of source select 
options of the UX2 (as requested in posting #12 in the above mentioned forum 
thread)?

[Line6linux-devel] Line6 TonePort UX2 issues

[<cp...@un...>]

Hey everyone,

I'm having a few problems with installing the Linux driver for my  
Line6 TonePort UX2.

Issue 1: Every other time I start up my computer, one of the Clip  
lights come on in the front. Not both, just one of them. It's very  
strange.

Issue 2: The instrument (normal) input is always active in my right  
speaker. When I play my guitar and it's connected to the instrument  
input, it plays through this speaker no matter what, except it is very  
distorted and noisy. Is there any way I can stop this?

Issue 3: I noticed in the documentation it was stated that the UX2 was  
not equipped with the Capture Source feature due to lack of response.  
I am wondering if there is any further update as I would like to be  
able to switch between all my available input sources.

Thank you for the help. Please let me know about any debugging steps  
you would like me to take. This driver is just one of the few issues  
standing between me and being Windows-free, so any help you guys can  
give me is very much welcome.

-Chris

[Line6linux-devel] Some comments and questions

[Aldrin M. <am...@dc...>]

Hello,

First, thank for your hard work: I've successfully do many things with
my pod xt live with Linux!!!


I've downloaded and checked the code. Two issues araise:

1. Can't we put this module in alsa? this way, this driver will appear
on may distros without much effort from the user part. Maybe some code
changes must be done to be aproved, but it will a plus.

I'm offering to help or do this work, if you wish. Are any licensing
issues pending?


2. I've seen the kernel module code, and found that many of the sysfs
hacks and handling of the device is done in kernel space, but the code
is mostly sending/receiving MIDI messages. I think is this plain wrong,
all this code must be in user space, not kernel space.

So, I think we should strip this code from the kernel module and put it
in some library. This will make disapear many of the sysfs files, but
anyway this must be put in the library not kernel. All current client
libraries for line6usb should send/receive standard midi messages
through alsa instead of reading/writing the sysfs. Besides, this will
make this client libraries more compatible with other line6 products:
think for example the flextone amps, which have a similiar midi protocol
but have no usb connection; the same library could be used if we connect
the flextone through a midi port. Besides, any error in this midi could
take serious consecuences, for example I've already hang my machine by
sending "random" midi messages to my line6 through alsa. I suspect there
are bugs in that code.


For making all of this work, we should take off all midi handling in
kernel and provide the raw midi device. And make sure it receives what
is expected: I found that line6 midi specs says that a channel dump is a
sysex message, but actually is sent with a FB first byte. The kernel
driver must make sure that what is received/sent in user space is the
same as the line6 midi specs. This make compatible the user library if
you connect a line6 device through usb or through a midi port.



I could help in both issues, I'm actually writing a python studio (DAW)
program and already created a python binding for alsa (It's available in
current 1.06rc2 alsa version). I plan to make a python library for line6
products, which you could use with any line6 product with midi support.
But I will like to hear your opinions first.

Best Regards,

It compiles fine. I'm not able to test it at the moment, because I don't
have my POD with me. build.log attached.

Hi,

Thanks very much for the driver for the various line 6 USB devices, I'm
looking forward to using it !

The attached trivial patch removes the use of snd_pcm_group_for_each
line6usb which has been removed in kernel version 2.6.22. With this
patch applied, the driver compiles fine with kernel 2.6.23.

Before hacking away at the driver to support my new X3 Live, I plugged
it in with USB and just watched /var/log/messages.  Here's what I got:

Looks like the product ID is: 0x414b

Does anyone have the bean-shaped X3 to see what it's device ID is?

Attached is a patch file for current SVN Trunk.  It's a start at
adding support for the X3 products to the driver.  Seeing as I don't
exactly know what I'm doing, it's not really working yet.

[Line6linux-devel] General method of controlling a POD XT USB device?

[Boyd T. <bti...@gm...>]

Could someone explain the general method of controlling a POD XT USB device?

I'm trying to wrap my hands around how this all works.  From what I
can tell, with older POD devices, you had to plug in a MIDI cable to
control the device (i.e., change amp models, effect settings, etc.).

With the newer PODs it looks like the controlling can done via USB.
My question is:

1. Do you control the POD using MIDI packets/commands still over the
USB interface

 -- or --

2. Do you use some other direct USB command to do the controlling?

I was fiddling around with the MIDI API in OS X just to get an
understanding of how this stuff works, but my POD X3 Live never seemed
to respond to any of the MIDI packets I sent it.  So now it's got me
wondering whether I should be using some other USB-direct command.  I
tried reading through the line6linux driver code, but I'm sure I'm
missing something because I haven't read through any driver
documentation for Linux yet.  It's on my todo list next.  :)

Thanks for any help you might offer,

Boyd

I installed the latest OS X drivers last night and the latest Line 6
Monkey and GearBox.  Monkey sees the X3 Live but GearBox doesn't
understand it.

I'm gonna sound completely stupid since I have no idea how this stuff
works, but reading through some of the source code and product manuals
on older products, it looks like communication with the POD is all
done via MIDI.  I sent a private message to Line6Miller on the user
discussion groups asking for an update MIDI CC Reference Chart for the
X3/X3 Live, but I'm not sure if they just hand that out.  I assume
that's what'd be needed to update the line6usb linux driver.

I've contemplated building something using Cocoa in OS X that just
does some simple slider controls to communicate with the X3's MIDI
interface.  But, since I've never done any MIDI programming in the
past, I'm not sure how easy/hard it'd be.  And, of course that'd be
using the OS X Line 6 drivers.

The other option for me would be to do the same thing using Gtk in
linux; or just wait until January '08 for Line 6 to release a newer
version of GearBox that works in OS X.

Are there already existing MIDI apps (free/open source ones) that
would let you tweak the X3's interface?

Boyd

Maybe this would push the project to the next step.

But, since there is no software update for the X3/X3Live in the download
area   of Line6 for Line6Edit or such software, there are two
possibilities for communicating with that devices:
	- Compatible with older PODS
 	- Editing software is still pending

So the question is: are the X3/X3Live are managebale with existing
Win/Mac software?

[Line6linux-devel] Anyone working on an X3/X3 Live Driver?

[Boyd T. <bti...@gm...>]

I just bought an X3 Live and saw this project.  I wondered if anyone's
already working on updating these drivers to use the X3 Live.  I would
love to help out.  I've written a few Gtk applications but have never
gotten into writing drivers.  Perhaps this would be a great place to
start.

Has anyone written a Gtk front-ends for controlling the PODS?

Thanks,
