From Kundalini WIki
The Kundalini Piano Mirror is a program for real-time manipulation of midi messages. It is designed for use with a digital piano, and has two main uses:
- Creating a left-handed piano
- Allowing a performer to write scripts which allow her to programmatically alter her dynamics, such as, for example, to achieve a smooth crecendo, despite differences in finger strength. This is called augmented dynamics.
