Sounds of the logistic map

• Logistic map of lambda = 3.7028 (4k midi file) First 500 notes on a 16 note Cmaj scale. This value of lambda is slightly chaotic tending to a seven note repeat.
• Logistic map of lambda = 3.8 (1k midi file) First 100 notes on a 16 note Cmaj scale.

• The Miraculous Bailey-Borwein-Plouffe Pi Algorithm The source of the c code for the conversion of numbers into chars.
• Günter Nagler's midi utilities with C++ sources and original compositions. I used his midi2txt and txt2midi programs to work out a method of translating the hexadecimal stream into notes. I also used the txt2midi program to produce the final midi files.
