takt 0.309 (new formula)

Takt is a text-based music programming language designed by Satoshi
Nishimura. It has the following features:

* It allows a concise description of note and chord sequences like
  `c d [e g]`.

* Expressive information such as dynamics or tempo rubato can be added
  to such note/chord sequences.

* It provides rich programming features including object-oriented
  support with C-like syntax. Such features enable seamless fusion of
  note-by-note description and algorithmic composition.

* Music transformation (such as transposition) can be applied to
  musical phrases described with the above means. Many predefined
  transformation modules are available; in addition; users can develop
  their own transformation modules with the language. Transformations
  can also be applied to standard MIDI files or events from a MIDI
  input device in a reactive way.
