FCC tools v.01
Open Music patches to produce, filter, transform and evaluate data.
The Open Music(1) patches in these folders have been used to produce, filter, transform and evaluate pitch, durational and spectral data over years of composing.
Some of them may be hopefully useful in computer-aided musicology toolkits as well.

The code in these folders is provided as it is, without any warranty.
It is freely available for everyone to download and modify as they see fit.
I would highly appreciate to receive:
– comments and bugs-reports
– examples to be used in future tutorials
– Max implementations (!)
I’m sorry for the poor documentation; I might extend it in the next release on your feedback.
Particular thanks are due to Michele Tadini and Conservatoire National Supérieur Musique et Danse de Lyon for inviting me to share my stuff.
