Secret Base Design has updated Live Guitar with lots of new features including Audiobus and interesting Twitter integration!

What's new in 1.3:

• Introducing Audiobus support
• Improved support for Virtual and Core MIDI
• Import/Export chord progressions through Twitter

Buy Live Guitar on iTunes: $1.99

Update: The free version was also updated over the weekend. Developer Fessaboy posted about it in a comment here:

No Audiobus, limited numbers of chord sets, and only one sample, but it's got all the MIDI goodness, and is probably useful to folks. If you dig it, please buy me a cup of coffee by going to the full version. If not, that's ok too!

You may recall my video from last week where I used Live Guitar's MIDI and Audiobus support to do some interesting iPolysix jamming. Another feature I was using was the ability to import whole chord progressions from songs via Twitter. This was really handy for me, because I don't have a fucking clue how to read guitar tabs. x03256? 330111?

Fortunately if you search Twitter for the #sbdlg tag, which you can do from inside of the app, you'll find a ton of tabs for many popular songs. You don't need a Twitter account to grab them either, but you will need one to tweet out your own.

Here is a demo of the new features!

Audanika continue their Harmony Theory Blog with Lesson 3, explaining where we get the names for notes and why we need them.

Read the whole thing, complete with pictures, on their website. Here is a little video exploring the circular relationship of the notes.

Just a couple of weeks ago Loopseque was updated with MIDI, and today they've added Audiobus support!

What's new in 2.6:

• Audiobus support.
• Minor bugs fixed.

Buy Loopseque on iTunes: $5.99

Unfortunately there is a known bug in Loopseque's Audiobus URL scheme. This is the way Audiobus launches other apps, so you'll have to launch Loopseque manually.

A fix has been submitted to Apple. In the mean time you can use Loopseque with Audiobus, just make sure you launch Loopseque before trying to connect to it!
