Since it might seem that I only post something when I come across a potential problem (which is often something specific to my setup or user error!), I thought I would post this:
I have used Cantabile 3 since before its official release, often using newly released experimental builds, and I am consistently impressed with both the quality of the application and the responsiveness with which Brad responds to all of the comments. As a software developer, I am very much aware of the difficulty of satisfying such a wide range of requirements and preferences.
I am confident that Cantabile will be the center of my performance rig for a long time to come.
