Version 2.01 improves version 2.00 by adding:

Step note-entry from a MIDI device.
Additional styles.
Textual editor for styles.
Improved preferences dialog.
Playback location tracker and seek.
Bug fixes for previous version.

This version, which runs on Windows, Mac, and Linux, is posted at:

(Note: In order to use external midi devices on a Mac, one needs to install
Plumstone:
http://www.cems.uwe.ac.uk/~lrlang/plumstone/ due to this being a Java app.
It is free.)

We are still a bit behind in updating documentation such as the tutorial.
