a nerdy little thing to try out the new Soundiron Rust libraries (not so new anymore at this stage) for Kontakt, using Fibonacci Numbers (F(n) = F(n-1) + F(n-2) with F(0) = 0 and F(1) = 1) eg:
time signature 5/8, 89 bpm, loop length 1, 2, 3, 5 measures, overall length 144
of course mistakes happen and loop 2 is only 7 measures (should be 8, which reminds me that a visit to the optician to get the glasses tested is overdue).
concept is only implemented with regard to measure length tempo and time, not harmonically, which would mean that steps between notes can be 1, 2, 3, 5, 8, 13, 21 etc semitones (or full notes, as you like).
all in all, just playing around.
