Euphonix’s "MC Mix" hardware control surface. A nice piece of kit, costs $999. It’s a little smaller than the Mackie Universal Controller, a plus in my opinion.

Unfortunately, the motorized movement of these faders can also be noisy, especially the clacking sounds emitted as many faders pop into position at once. This can be distracting when trying to mix a quiet, emotional scene. These controllers are also pretty expensive, starting at about $1000.

Enter the iPad and Saitara Software’s “AC-7 Pro Control Surface”:

The control surface in the video looks very cool to me. It’s silent, can be seen in a dark editing room, appears to function as well as I’d need, and the cost of the app is only $9.99. I’ve played with a friend’s iPad, and know the touch-sensitivity of that screen is accurate and responsive enough that I’d have no problem adjusting several tracks at once with this interface. For those addicted to the feel of hardware faders this might not cut it¹, but for me it’d be a big improvement over moving the faders in Final Cut Pro’s “Audio Mixer” window with a mouse. I can’t justify spending $1200 on a set of faders I’d barely touch except a bit towards the end of a project, but $10² ? Hmm.

Yet another reason to consider an iPad. I wonder how long I’ll hold out? Sigh.

1. I don’t think this is just a matter of purely subjective preference –one can feel where a hardware fader’s control is in space, and there’s probably a bit of resistance built in so the user can feel when the level has been set at unity without having to look.
2. $510 if factoring in the cost of an iPad, which can also be used to access the iPoo social network.

The crippled feature to be healed and exploited

How iTunes sharing works

If a copy of iTunes is running on any other computers that are on the local network, those instances of iTunes will notice the advertisement of an iTunes share on the network, and will display the name of that iTunes share in the left column of the window. The user can then click that shared Library and play songs from it on their computer. The playlists and songs stream over the network from the sharer to the sharee. Unfortunately in my case, iTunes running on my laptop at work couldn’t see the iTunes share served from my computer at home, because my home computer is miles away and not connected to the same local network as my laptop.

Bringing the remote network closer

REMOTE ITUNES SHARING

I recognized a familiar Unix trick in their tip: Port forwarding over a secure shell connection. Of course! If one could make a secure shell connection (abbreviated in the command “ssh”) to a remote computer, one could then do what’s called “port forwarding”, and forward all communications on a port on the remote machine to a port on the local machine. This would transport both the advertisement of the iTunes share and the actual sharing itself from the remote network to the local network. I’d never actually executed port forwarding over ssh before, but I’d heard of it, and between their example and the man page for the ’ssh’ command, it all became clear. The tip first requires that one knows the IP address of the remote computer, and then shows the command to connect to the remote machine, grab any communications on port 3689 (the port used by iTunes sharing), transport it encrypted to the local machine, and repeat it on port 36890 of the local machine. The command looks like this (hover your mouse over any portion of the command to see an explanation of that portion):

$ ssh -fNL *:36890:127.0.0.1:3689 USER@REMOTE-HOST

After that command successfully concludes, the iTunes share on the remote computer will be accessible to computers on the local network, except they won’t be able to see that it’s there. The second command in their document uses OS X’s built-in “dns-sd” command to advertise that there is an iTunes share on port 36890 of the local computer. It is this advertisement that will make the iTunes share appear in the sidebars of any copy of iTunes running on the network:

$ dns-sd -R "Remote iTunes" _daap._tcp local 36890 &

I was confident that this would all work, but for one snag. Like most people, my home computer only has an address on its local network, it doesn’t have its own internet address. The computer is connected to a router. The router has an IP address on the internet and an IP address on the local network and uses what’s called “Network Address Translation” to distribute connections from the outside internet to all the computers on the local network. If I tried to connect to the IP address of my home connection, I’d be connecting to the router, not my home computer with its trove of music. Luckily a solution was within reach.

Locating the remote computer using Back to My Mac

Wherever you go, there’s your Mac.

Back to My Mac puts any Mac OS X Leopard- or Snow Leopard-based Mac you use within easy reach. MobileMe finds your remote Mac computers over the Internet and displays them in the Finder on the Mac you’re using. So you can connect from anywhere with just a click. Edit and save documents, open applications, and move folders. With Back to My Mac Screen Sharing, you can control your remote Mac as though you’re sitting in front of it.

I have been using the Back to My Mac service to copy files to and from my remote computer from work, and to occasionally take control of my home computer’s screen from work. The service must be punching through the router using port-forwarding and registering a temporary domain name for my home computer which can be accessed from the outside internet. I figured that if I could find out this domain name, it would be worth a try to use it to connect from work to the home computer and set up ssh port forwarding of the iTunes share. A search turned up this article:

10.5: How to use ssh using ‘Back to My Mac’

The writer of that article explains exactly how to determine the Back to My Mac domain name at which one can find their remote computer. When I tried the first method described, it did not work. As it turns out, that method works for short computer names, but my home computer’s name is long, and Back to My Mac truncates it and adds a few random (?) numbers when assigning the domain name. The second method they mention does work. I can easily determine the name assigned to my remote machine by choosing “Shell > New Remote Connection…” in the Terminal application’s menubar. In the “New Remote Connection” window that appears, I choose ’ssh’ in the service column and my remote computer’s name in the ‘Server’ column. There, in the field at the bottom of the New Remote Connection window will appear the command for making a ssh connection to my home computer. It’s not the same ssh connection command that will be used to do port forwarding, but the last portion of it does show me the exact domain name that will resolve to my home computer.

1. All the solutions written below involve the use of the Terminal application and the command-line. If you’ve never played with such, give it a shot. Stop kvetching and open /Applications/Utilities/Terminal. You paid for a Unix operating system when you bought your Mac, you might as well try exploring some of its inner awesomeness.

Always one to obediently follow directions, I ripped, signed, and sent. I also listened, and damned if it isn’t a great little album. Here’s the first track, “Forget Everything”, for your streaming or downloading pleasure¹ :

01 Forget Everything.mp3download mp3

I’d highly recommend that you receive this album by mail from a friend or an anonymous source. Failing that, the mysterious band² has a website, a myspace page³, and the album is available at both the iTunes music store and the Amazon MP3 store.

1. Hit the triangle button to play the track in your browser, or the download link to download the mp3 file
2. Their myspace page doesn’t list the names of band members, their number, or even a location.
3. The album can be listened to on the page in that icky myspace music player widget.

Shure makes a set of earbuds called the i2c, which are simply their e2c earbuds with the addition of thicker cables, an inline microphone, and an iPod connector (looks like a standard 3.5″ stereo jack except it has one extra conductor for the mic). As an iPhone headset, the i2c has faced some criticism due to the fact that it lacks an inline answer/hangup button. Perhaps because of this minor inconvenience, Amazon.com has recently dropped the price of the i2c headsets from $119 to about $39.

I don’t care about the button, or the mic, since I don’t have an iPhone. For a nice pair of earbuds, that price happens to be a great deal. I placed my order last week thinking that if the iphone plug wasn’t compatible with my ipods that I’d cut it off and solder a standard miniplug in its place (ignoring the mic wire). It turns out that the iPhone connector works fine in both my 1st-gen iPod Nano and 1st-gen iPod Touch. Right and left channels nicely separate, and the sound is good. The mic connector on the plug doesn’t seem to short or otherwise interfere with the contacts for the audio outputs –your mileage may vary. It’s working for me (I suspect the connector was designed to work in both iPhone and standard mini-stereo jacks, but don’t quote me on that).

If you buy a pair of i2c’s (or any in-ear monitors really) I’d recommend tossing the silicone sleeves they ship with (with extreme prejudice) and instead using compressible foam tips so that the earbuds really make a nice seal in your ear. The sound quality will be much improved, and the bass presence and detail will increase. Shure sells orange foams that works well, many on the net tout Shure’s tapered black “olive” foam sleeves for greater comfort and cleanability, and I’ve heard good things about the Comply viscoelastic polyurethane memory foam tips.

I ‘m happy to now have a nice pair of earbuds to use for running (My Future Sonics FS1’s finally died, and I don’t want to subject my FS Atrios to the same abuse). Yay. If you’ve been thinking of replacing your iPod earbuds with something better, this here’s a very good deal (on something much much better).

Tokyo Police Club played The Music Box last night, and I and a friend who likes to go nameless attended. I thought the show was great, and found the band’s amped-up shoegazer style refreshing, he had the opposite reaction, and left early. I think it helps to hear their music and know some lyrics beforehand –it’s deceptively non-accessible stuff despite the driving beat. The acoustics in the club were such that it was difficult to pick out the different layers of sound.

I shot a few photos with my digital point-and-shoot, they can be accessed by clicking the photos in this post.
