is it possible to program a range of the sample duration jitter in the sample cloud sound. as i understand the manual the duration dev. can vary from 0 to twice the duration set in the duration setting. how can i make it vary between letīs say 0.5 of the duration and twice the duration? can the grain envelope be a constant? how can i prevent an envelope fading down the sample before it reaches the end? frank.

Try using RectangularSmoothed as the envelope wavetable. That will give you close to a straight on/off without actually clicking. If you set the grain duration deviation to 0.5 that will vary between 0.5 and 1.5 times your specified grain duration. In general, the grain dur varies between ((1 - deviation) * grainDur) and ((1 + deviation) * grainDur). IP: Logged |

has the length of the envelope got something to do with the actual length of the output grain? IP: Logged |

The envelope length is set by a combination of the GrainDur and GrainDurJitter fields. IP: Logged |

hereīs my problem: my sample is 30 seconds long and i entered a grain duration of 10 seconds and a duration deviation of 0.5. time index is -1 and index jitter is 0. evelope is smoothed rectangle. mx grains is 1. all grains that come out are about 2 seconds long, no matter how long i set the grain duration. the only change happens when i set it under 2 seconds. this sound should produce the sound of a telefone ringing fron time to time with a random length from ca. 5seconds to 10 seconds. so i set a very low desity.

Right now, the maximum duration of the envelope in the SampleCloud is 1 second. But I think you should be able to achieve the desired result by using a Sample with a random trigger. Paste a FunctionGenerator into the Gate field of the Sample. In the FunctionGenerator use 0.1 s random abs lt: !Density * 0.1 for the Trigger, (0.1 s random abs * 5 + 5) s for the OnDuration, and Rectangular for the Wavetable. This results in the Sample being triggered for 5-10 seconds at a random rate determined by the Density. IP: Logged |
