Is there a way to calculate logarithms in Sonic Pi? I want to write music in just intonation and I’d rather not have to manually perform the calculations myself each time I enter a note.
try this Ruby function
EDIT th above gives log base e If you want a differnt base use
live_loop :test_log_in_ruby do tick puts "x=", look, "log(x)=", Math.log(look) sleep 1 end
Thanks everyone! And I just realised that there’s another way to write just intonation music -
# c scale ..... a = 440 # 24,27,30,32,36,40,45,48 midinumber=[:r] for justnumber in 1..96 midinumber[justnumber] = hz_to_midi(justnumber*11) end puts midinumber
