capella 7 has evolved over 15 years to become a professional quality notation program at an affordable price. It has additional modules designed to work with it to scan music, create MP3 fiiles and automatically harmonize and compose canons and fugues.
capella start has almost all the features of the unrestricted capella 7 but is restricted to 4 staves of 2 voices and 100 bars total score length. If your music is for piano or no more than 4 instruments it is a very cost effective product.
Lyrics are automatically linked to notes and text can be entered either independent of the notation size or linked to it so that it scales when the stave size changes.
