Getting Line 6 POD Studio UX2 to work on Linux

I was blessed to have a friend who lent me their recording gear. Here's what I did with it =P

Seek and you shall find

Luckily, someone (Markus Grabner) wrote a driver for Line 6 devices on Linux here:
http://line6.com/supportarchivenew/thread/4031
Their website is here: http://www.tanzband-scream.at/line6/
Note the link to the source code on that webpage is old - the latest should be v0.9.1beta not v0.8.1

Getting the latest version

Using svn to checkout the repo and make didn't work (I got a bunch of errors, possibly due to using svn to clone the repo causing the make command to create a bad revision.h file. I also got errors from driver.c

To get around the errors, I tried downloading the zip from sourceforge here:
http://sourceforge.net/p/line6linux/code/HEAD/tree/
(Click "Download Snapshot"). 

After that, just unzip, go to the "drivers" folder, "trunk" branch then $make and #make install inside that directory. Btw, for dependences, you need gcc, make, your kernel's headers (e.g. linux-headers-generic), and alsamixergui + pavucontrol (for later).

Here's a nice article about ./configure, make and #make install. http://www.codecoffee.com/tipsforlinux/articles/27.html

Plugging it in

Now for the harder part, thanks to bkmfs2 on the line6.com forums in the 1st link of this post we have:

#Then you have to find your soundcard with:
cat /proc/asound/cards
#This tells you how your Line 6 device viewed by the computer ('hw:' number).
#Replace 'hw:1' with whatever shows up for your sound card when you type:
alsamixergui -D hw:1
#You HAVE TO turn the 'monitor' slider all the way down or things will crash (unless the 'svn' site has a newer version that fixes this).
#Just so you know, the thing is a little volitile but I was able to use my Line 6 UX2 with jack-audio with (so far) dependable success.
#Just F.Y.I., I bought a M-Audio MobilePre the other day and it works right out of the box.

I didn't have to get alsamixergui to select the device to control - I use Audacity and it allows you to switch between devices.
My favourite audio setup/control tool on linux has to be pavucontrol although I couldn't use it for audio in and I could use Audacity to select the hw2:0 device for recording, letting me record.

By using the monitor turned up to 100% in the alsamixergui, I was able to hear the input from my mic, albeit quite distorted. It obviously was more clipped when I turned up the "phones" dial and/or turned up the monitor signal from aslamixergui. This is mentioned in 4.3.5 of the driver doc manual PDF (from Markus Grabner's Tanzband-scream.net website), but I haven't been able to fix it yet. The PCM audio works phone though, using the computer to play to the phones without clipping.

I decided to get the full experience dual-booting into Windows and using POD farm (didn't want to set up WINE/VM as I was short on time and didn't want to troubleshoot any errors that would come up). However, I didn't have time to do that either (only effectively had one afternoon) so I just stuck with recording in Audacity on Linux.

Yes, this means you might get to see some art/annihilation related projects released soon showcasing the results.

Ubunchu ch.08 and PSA: Sudo powers

Here's a double release of art projects geared towards new(ish?) users/discoverers of Linux and the Ubuntu distribution.

Ubunchu chapter 8 typeset by me took a year (lol, I had no schedule and it was very on-off, next time I'll schedule it properly so I don't forget what I was doing). It's my first official type-setting/translation manga release, hope you like it. =) I was going to try and perfect it but because the project dragged on so long I thought I should just try and quickly push it out and release/ship it.
Ubunchu is about a school club in a Japanese high school which is tinkering with Ubuntu.
Read the whole series (and a better synopsis) here: ubunchu.net
My latest release (ch8): on google drive - zip of PNGs (click File -> Download),

        Shared folder here - DL in PDF (recommend you DL the zip of PNGs instead and use MComix to read get MComix1.00), 

        and on the ubunchu website (when it gets uploaded there someday).

Getting to work on an open sourced manga/project like this one is pretty nice. Especially without having to clean 'scans' using levelling, and other more sophisticated techniques. xP All of it was done in GIMP which is open source and is also available on windows due to GTK magic (but it feels nicer on my Kubuntu). I've never used photoshop properly (to a certain extent) but I can say GIMP is competitively advanced and has nice plugins too. Mostly used Blambot's fonts - free for non-commercial use.

Also would be nice to get a Wacom tablet/ergonomic mouse/SteamController (check out this demo vid!), I get RSI with at least my index finger when using conventional mice. Currently use a trackball for everyday use, but gets annoying since it doesn't have a scroll wheel. Steam controller definitely looks promising since my HKD20 PS-like controller definitely has bad resolution, and I don't imagine my PS controllers or the XBox ones will be much better. Although having fond memories of my Saitek joystick (which is so old it used a serial or parallel connection), I might use that for Star Citizen, although I'll have to test the Steam Controller first, like how I tested the OR. Which reminds me, Oculus Rift post coming soon =)

[Linux is complete with gaming rant]
With Valve's SteamOS, Steam on Linux and Source, Unity, Unreal game Engines being native on Linux as well as CryEngine soon, games seem to be moving en-masse to the Linux OS. This is welcome news, since gaming, and atm, only one particular game (Star Citizen, which has gained 4mil in crowdfunding since I last blogged about last month - 1.5mil of which was from the last 4 days) is the only thing holding me back from never booting Windows on my laptop. It's on CryEngine 3, so can't wait for that to build natively for Linux.
We've got Dota 2, KSP, Guns of Icarus Online, L4D2, TF2, X-series and an increasing amount of games, indie and big-publisher alike natively on Linux already or coming. I find if I'm looking at a game purchase/Humble Bundle, availability is a deciding factor. These next few years will be very interesting for Linux =)

Here's the PSA (it's related to Ubunchu ch.8), sad to say I learnt this the hard way one too many times:

Came across an interesting blenderguru post about why and how Blender's UI is broken and the principles of making good UI, how Blender can be fixed. The folks who made Unity should have a look =P [Sincerely, KDE/XFCE user]

UPDATE: Blenderguru made a video with suggestions, here it is!


=)

OpenShot video editor v 2

So I realise I've been blogging about games (most on Linux) lately, especially with my yearning for Star Citizen to hurry up and get made.
This post, I won't use the 'games' tag. =)

So I was casually browsing kickstarter as you do, and found THIS. Evoking memories of trying hard to find a proper video editing software, finding the most feature filled one on Linux being a readily crashable OpenShot video editor ;P It also kind of reminds me of getting blender and being completely stumped at how to use it. (Along with Maya).
This was back in 2010, and we were able to put together a simple video:


Now, I'm happy to see more work being done, OpenShot getting a new framework, fixing apparently 99% of previous bugs, and cross-platform support.
Oh, and they're switching to Qt from GTK. I liked GTK back on Ubuntu10.04 with GNOME, because Qt would usually look ugly or fail, but now that I'm on Kubuntu12.04, both work pretty well from an end-user point of view. Here's a funny port GIMP to Qt thread that descends into mini-flamewar from the middle till near the end.
Anyway, obligatory iframe of latest blog post (which includes a restrained comment on Operating Systems for devs which I can understand/agree upon):


P.S. Yes, I'm running out of holidays to finish two arty projects in the works, one which was intended to be released a while ago =S; Also, may be starting a eng/tech project (finally!)

News post #11?

http://www.technologyreview.com/news/506466/given-tablets-but-no-teachers-ethiopian-children-teach-themselves/
Woot, u go, hacker children!!
Personally, I think humans are naturally hackers and makers, curious about things, tinkering with them, and wanting to make/create things. This bit of news kind of supports my thought =P
Also, good to see OLPC is doing stuff, their $100 XO-1 is pretty neat too, I've seen it in action before at ASSC, one of the guys from Lunar Numbat brought it along =)
Speaking of which, haven't heard much news from LN and White Label Space, but Canberra UAV had a pretty good year, and they presented at CLUG too! =D

Yep, lots of group dropping there =P Don't forget the hackerspaces I follow: MHV and HackJamHK@Dimsumlabs(-their FB page is pretty well updated) =D
Being a Melbourne boy, it's kinda sad I dont' follow these guys (CCHS) nearly as much (due to me not being around Melbourne -my fav city- as much as the other two places these days! ><") though some of them are LN and they've had some pretty cool projects. Their computer-in-car is especially cool =P and is part of the inspiration for Project Sheila (now much easier with mobile computing and Li batteries =D) which first requires a car and license (lol) xD Anyone get the project name reference? (Hint, my AI will be called Sheila).

In other cool news:

First whole carbon solar cell including electrodes (apparently some researchers as engadget points out, has made the energy transducer part before)
Pretty cool.

Project Anihilation - Red Vs Blue Intro Cover 01

I'm surprised the first product of Project Annihilation was from India (Instrumental) sub-section. I was planning some Alpha ones.
First time ever I've done this. Made with audacity and windows movie maker. I'm looking into some better video editting software - windows movie maker is just too limited.
I used a classical guitar so I didn't have as much re-verb and I wanted to keep the audio as untouched/unedited as possible.

Oh well, enjoy!
