Calculate frequencies for even octave divisions in ChucK

even-tuning.ck

SinOsc s => dac; // could be any unit generator
440.0 => float baseFreq; // starting frequency
5.0 => float divs; // number of even divisions of the octave
1 => int i; // number of steps above base

// Playtest
// baseFreq => s.freq; // play base freq
// 1::second => now; 


i/divs => float exp;
Math.pow (2, exp) => float mult;
baseFreq * mult => s.freq;

// Playtest
// 1::second => now;
