Using Mathematica 6.0.2, I can't get this relatively straight forward code to
work, Can anyone explain what's wrong and how to fix it. It's
essentially intended to be musician utility for using the SoundNote
function which I hope to further elaborate by also converting any
(MIDI note range frequency) into the appropriate MIDI note number and
pitch bend values assumming a fine tuning RPN range of +/- 1 semitone,
allowing 100 cents "sensitivity" to be defined.
Manipulate[
DynamicModule[{f, m, s, sd, pt, p, o},
f = N[(440/64) 2^((m + 3)/12)];
sd = {"C", "C#", "D", "D#", "E", "F",
"F#", "G", "G#", "A", "A#", "B"};
s = m - 60;
pt = Mod[m, 12];
p = sd[[pt + 1]];
o = Integer[m/12] - 1;
Print[
"MIDI Note Number (0-127)", m,
" equals ", f, " Hertz (8-12600)",
", and its SoundNote number (-60 to 67) is ", s,
", which has the Pitch name of (C to B) ", p,
" in Octave (-1 to 9) ", o, "."
