Other promising features that could use just a touch more refinement are GarageBands new track-notation view and pitch-shifting functions. The notation view errs on the side of producing legible scores at the expense of rhythmic accuracyit missed a few triplets and dotted rhythms in my tests. And you can neither change meters and key signatures in these scores nor print the scores. Amateur musicians will appreciate the resulting scores clarity, but pros needing more notation capabilities should look to Logic Express, Mark of the Unicorns Digital Performer, or Steinbergs Cubase.
