How do I record a Sound to disk if it has VCS controls and I have tweeked them to get the effect I want? Say I take a SampleCloud and adjust the index, density, etc. to get the desired effect. Now if I use "Record to disk..." from the Action menu, all of the settings in the VCS change. It doesn't seem to matter if I save the sound first, or even if I take a snapshot and save that. (I even tried re-nameing the snapshot to "Default") Seems like a pretty basic thing to want to do... Bill Meadows p.s. - Please add "Frequency" to the SampleCloud. There are so many programs out there that already do this - e.g.: Thonk, Cloud Generator, plug-ins for Digital Performer. IP: Logged | |

I've been told that they are working on a frequency parameter for the sample cloud. Meantime here's my own version of a granulator including feedback. I'm sure there are things that can be done to improve it - have a look and let me know. Gareth IP: Logged | |

Yes, Jürgen Krehan discovered this bug with recording last week. We have it fixed and hope to upload an update as soon as we have packed and shipped all of the crates for the upcoming AES show in Los Angeles. Thanks for the report & we hope to get you the fix by early next week. IP: Logged | |

quote: Gareth - This is a pretty good work-around. I thought about this approach awhile back, but didn't think it would work because the GrainCloud doesn't have a "from MemoryWriter" check box. (e.g. - like SampleCloud) How does it know that "recording" (or whatever) isn't a waveform on disk somewhere? Seems inconsistent to me. One other thing to note: when you placed that lowpass filter after the GrainCloud, it summed the left and right channels, so "PanJitter" no longer has any effect. I really wish Kyma would use separate left and right ports on the icons so one could keep the signal path (stereo/mono) clear. Bill IP: Logged | |

This is a pretty good work-around. I thought about this approach awhile back, but didn't think it would work because the GrainCloud doesn't have a "from MemoryWriter" check box. (e.g. - like SampleCloud) How does it know that "recording" (or whatever) isn't a waveform on disk somewhere? Seems inconsistent to me. Yes I half expected it not to recognise the file name - a bit of beginner's luck! One other thing to note: when you placed that lowpass filter after the GrainCloud, it summed the left and right channels, so "PanJitter" no longer has any effect. Agreed, I also find this confusing. Sometimes I want to do totally differerent things to the left and right channels but its hell to sort them out. Thanks for the tip though I'll deal with that. Also I'm using a variable highpass filter to get rid of DC bias in the feedback loop - this could be done more efficiently. It clicks on some settings too - any ideas for that?

quote: The clicking is due to the frequency shift. You are reading faster or slower than the MemoryWriter is writing into the buffer, so there is a discontinuity when you pass the write pointer. This is similar to the the problem mentioned awhile back by someone trying to do reverse delay. I have an "old-style" pitch shifter that Carla sent me that might solve the problem, I'll look into it. Ideally, of course, SSC would add frequency control to the SampleCloud. As far as the volume goes, I think you have !Density in the amplitude parameter. (I don't have your patch in front of me, so my memory could be off.) I thought you did that on purpose! Bill IP: Logged | |

Cheers Bill. I tried to substitute a stereo LP filter for the mono one to regain pan jitter but I can't figure out how to assign the left and right outputs of the grain cloud to it - it keeps sending the same signal to each filter channel. You're absolutely right about the amplitude - oops  > I also notice that there are unnecessary things in there like the time offset which is a hangover from some earlier experiments. I'd be keen to have a look at your alternative pitch shifting solution. I used a pitch shifter in another version but I'm not entirely happy with it - it only works on monophonic inputs.Gareth

I too am suprised that the grain cloud works with a writer but Gareth you have prooved that it does. I'm well impressed. Any way there are two reasons for the clicks, one is as bill said (the reader and writer crossing over), the other as that the grain cloud is expecting a waveform as its source and has a fixed size of 4096 samples. So if we make the writer the same size we will only get clicks if we shift the pitch. This means that although the grain length can be anything, the maximum time shift that any grain can be reletive to the original signal is 4096 samples or 93 ms (at 44.1 khz sample rate).Gareths feedback path helps to mask this limitation. I've attached an adjusted module that puts freq in terms of pitchshift so that one = no shift, gran duration of one= 4096 samples and density= number of grains. I've removed the HPlevel as it was realy doing the same job as feedback. I've added a level control as both density and feedback can cause cliping. I've also compensated the feedback with the level control as they are interlinked but as you move the level control you can cause extra feedback until it stops moving. Also I have added the sterio filter a you talked about. At the moment you have to move the right hand signal to the left, then do the work and then move it back to the right. I am sure this will change soon with all the new multichannel outputs, but for the time being I think this is the only way to do it. So until there is a new pitch controled sample cloud, I hope this helps. regards p.s. To get your old presets to do anything you must up the density control. I had to cut the max density to 20 grains as my little home cappy 66 ran out of the magic juice. IP: Logged |
