www.notation.com/MidiNotateBetaRelease.htm

If you are using any prior version of Composer, it will be necessary for you to download and install version 1.9.11. (No patches from previous beta versions are available.)

Composer beta release version 1.9.11 includes the following enhancements:

New Song Wizard. The New Song Wizard has been much improved. As you make choices for the ensemble, meter, key signature, measure count, and song title, you can watch the score evolve according to your choices.

Importing MIDI files. Composer now analyzes with tracks in the imported MIDI file are probably keyboard tracks that need the Split Hands to be applied, or which are right- and left-hand keyboard staves that are in the incorrect order which needs to be reversed. You have a chance to review Composer's recommendations before it applies the corrections.

Parts. The "parts" feature of Composer has been reorganized to make it more intuitive. Many commands in the Parts menu have been moved to a new Change Part dialog, which more clearly shows the relationship between staves and parts. For example, a piano part typically has two staves. There is also a new Add Keyboard RH and LH Staves command in the Staff menu, to create a pair of right- and left-hand staves for a keyboard part, with an brace added to the left of the pair of staves.
