Pentatonic Permutations

Pentatonic Permutations is an algorithmic piano music composition that started with the Big Bang 13.799 billion years ago and will continue another 16 trillion years and then stop. It uses the Japanese 1-4-2-3-2 Kokin-Joshi scale that is also known in India as Raga Vibhavari (Revati).

Each moment of time is tagged with a unique predetermined melody that never repeats until the last permutation is played. The composition is synchronous and realtime. Each Pentatonic Permutations Player (PPP) and each computer are playing the same part of the composition. You are listening to the same notes in this moment of time as everyone else.

Different Reverb algorithms can be selected. I prefer "Chapel".

"Echo" in the Reverb pulldown generates a 4 sec Echo.
