Since many years I’m working with the Capella software. This Software is liable to pay costs, but there is a free Reader.

 

Capella:

• Capella 8.0
• more modules for Capella

 

Capella-Reader:

• Download  newest version

 

Font package:

For the continuo of some cantatas (and other works) you need the Capella-Generalbass true type font.

• Download Capella-Generalbass.ttf
• Download keyboard layout for the font
