object DegreeToKey extends Serializable
A UGen that uses an input signal as an index into an octave repeating table of pitch classes. The input is truncated to an integer, and indices wrap around the table and shift octaves as they do.
Examples
// modal space where mouse x controls pitch step play { // initialize the scale buffer (Dorian) val scale = Vector(0, 2, 3.2, 5, 7, 9, 10) val buf = LocalBuf(scale.size) SetBuf(buf, scale) // base MIDI pitch val base = DegreeToKey.kr(buf, in = MouseX.kr(0, 15), octave = 12) + 72 val noise = LFNoise1.kr(Seq(3, 3)) * 0.04 // low freq stereo detuning // lead tone val lead = SinOsc.ar((base + noise).midicps) // drone 5ths val drone = RLPF.ar(LFPulse.ar(Seq(48.midicps, 55.midicps), 0.15), SinOsc.kr(0.1).madd(10, 72).midicps, 0.1) val mix = (lead + drone) * 0.1 // add some 70's euro-space-rock echo CombN.ar(mix, 0.31, 0.31, 2) + mix }
