WAVE->MIDI: Recorded music can be converted into score! WIDI is one of the best tools that allows polyphonic conversion. You can take you favorite audio record, convert it into notes and than do with it anything you like. You can even record your own voice and then convert it into score! MIDI files are much more flexible than WAVE - you can reassign instruments, change tempo, add or delete some notes and so on, you can use your favorite Musical Editor such as CakeWalk to do that. This software is improved constantly, check the WIDI web site periodically for updates.
