This is obscure, but happened with Loup and was fixed by using the answer from the following SO post

http://stackoverflow.com/questions/13133883/having-difficulty-pulling-repository-from-assembla

ipadOscMidi app with Max patch

Have set up a Github repository for the ipadOscMidi simulator app: https://github.com/tkzic/ipadoscmidi

There is also a companion Max patch for testing

Here is the README file for the project:

ipadMidiOsc
-----------
March 4, 2013
version 1.0

This program is a simulator to test Midi and Osc communication in iOS. There is a companion Max/MSP patch in the archive (oscmiditest3.maxpat). The Max patch lets you control the user interface on the iPad. And it well display incoming messages from the iPad.

I have only tested the default iOS midi networking devices via Mac OS, and an iRig Midi interface. 

This is the only documentation right now - but there are big plans, yeah, for a programming guide, and a free app store app, along the lines of audioGraph.

I wanted to get this initial version out before the spacecraft lands in the backyard.

Acknowledgements:

The Midi code was derived from PGMidi by Pete Goodliffe
The Osc code was derived from OscPack by Ross Bencina

Thank you.

Updates to audiograph for iOS 6

notes

Today I’m attempting to update audiograph to run under the current iOS/xcode releases. Here are some helpful solutions to resolving compilation errors and warnings…

(update) Had problems with git, because I forgot to pull the changes from Michael Tyson, down from github before I made changes to the files locally and committed them.

Ended up doing a wholesale copy and a lot of duplicated effort – anyway it seems to work now.

Very important: The current local version of audiograph is in tkzic/coreaudio/audiograph

I have also submitted a new version 1.1 to app store. but its in the same folder I just mentioned.

deprecated AvAudioSession methods (iOS 6.0)

I commented these out and added the updated methods

The ‘play’ button on the bottom toolbar didn’t work on the 5g ipod touch (with taller screen)

Here’s what fixed it (in applicationDidFinishLaunching…)

from this stack overflow post: http://stackoverflow.com/questions/12395200/how-to-develop-or-migrate-apps-for-iphone-5-screen-resolution

The only really required thing to do is to add a launch image named “[email protected]” to the app resources, and in general case (if you’re lucky enough) the app will work correctly.

In case the app does not handle touch events, then make sure that the key window has the proper size. The workaround is to set the proper frame:

<code>[window setFrame:[[UIScreen mainScreen] bounds]]</code>

There are other issues not related to screen size when migrating to iOS 6. Read iOS 6.0 Release Notesfor details.
