I just read the Audiobus article on TUAW
and ask myself if this is a step in the
right direction... I always saw the iPad as a single task device.
I could record a synth app like iPolysix or Animoog directly into Garageband on the iPad,
then a such a performance would end up very gracefully into Logic Pro
But then again, I cannot imagine apple supporting a third party mechanism. Let's hope
they will build it into CoreMidi / CoreAudio ...
