Can MusEdit create notation from performance with a live instrument?
This is similar to the problem of CD music versus Midi music… The sound created by the vibrating strings of a guitar is too complicated for MusEdit to decode into notation, but if you have an instrument with Midi output (such as an electronic keyboard, or a guitar with a Midi pickup) you can hook this up to your computer and MusEdit will do a pretty good job of converting your playing into notation.
