... i was wanting to make a self-generating melody type of sound in kyma. something simple involving soft sinewaves... and thought perhaps of using a randomizer to choose pitches and note locations.... what sort of (nextRandom) expression could be used in a Pitch parameter field that would restrict the choices to a particular key.. C-minor, etc.... ? thanks.... IP: Logged |

One approach might be to use the random number as an index into an array... For example: (((1 bpm: !BPM) nextRandom abs * 8) of: #(60 62 63 65 67 69 71)) nn IP: Logged |

*bonk* of course.. i feel stupid! i knew that... what is the abs * 8 portion of that expression there for, though? why not just have it choose a nextRandom of the nn you have supplied? thanks

That was an error. It should be * 7, because there are 7 elements in the array. IP: Logged |
