Fripp 0.2

Fripp is a music composition environment that uses a spreadsheet metaphor for entering music and manipulating it with built-in and user-created functions. The project supports MIDI playback and recording, and displays music in common notation.
Scores can be exported to Mup format for high quality printing. The core program is written in Python, and the user interface is implemented using the wxPython toolkit.
Main features:
- Enter "music" into cells of a spreadsheet. The columns of the spreadsheet contain the bars of your score, and the rows contain the staves. So each cell contains one bars worth of music for one staff.
- Play the score from one or more MIDI instruments connected to your computer, if you have the (free) KeyKit application installed.
- Export the score to a file for high-quality rendering with the Mup music publication program.
- Organize compositions in workbooks, which can contain multiple scores. The picture above shows a workbook named "Lipstick", which contains three scores. The active score is called "Truly Almond".
- Enter formulas into the spreadsheet cells, to generate new music or transform other music in the score. Formulas can use built-in functions such as:
- Reverse(): Return the reverse of a given musical phrase.
- ReverseTime(): Return a transformation of a given musical phrase, with the pitches in the same order as the original, but their durations in reverse order.
- ReversePitches(): Return a transformation of a given musical phrase, with the durations in the same order as the original, but their pitches in reverse order.
- Transpose(): Return a transposition of a given musical phrase.
- etc.
- Write your own functions in Python, to generate or transform musical phrases, or to control other aspects of the score, such as tempo, meter, key, or instrumentation.
- Write rich-formatted, hyperlinked notes about your scores, and store them in the workbooks.
- Automate Fripp with your own Python scripts.
