Ableton has just released "Note" for IPad... will Native Instruments finally update iMaschine 2?
Ableton Note
Double your loops to create variation within clips. Then duplicate your clips and experiment with different versions of your idea in Note’s Session View layout. Create eight tracks with up to eight clips on eight scenes, and use the Scene Launcher to experiment with building it up, stripping it back, and trying out combinations of layers.
When you like the way your clips are arranged, export your project as an audio file to share with friends and collaborators.
