Re: [PD] euclidean rhythms
Do you want to have a similar GUI as well? Pierre 2011/5/26 Martin Dupras martindup...@gmail.com I had a quick read of the paper just now. I might have missed the point altogether, but from what I understand, the results that he gets from the Euclidian algorithm are the same (if you accept a rotation pattern as being equivalent) as what you'd get from the simple rounding of fractions. In other words: let's say you want 5 beats in a grid of 12 (or a 12-sided polygon, if we use his graphical representation), the exact spacing between two beats would be 12/5, or 2.4. The first beat would be 0*2.4= 0. The second beat would 1*2.4 = 2.4, rounded to 2 The third would be 2*2.4 = 4.8, which we round to 5. The fourth would be 3*2.4= 7.2, which we round to 7. The fifth would be 4*2.4 = 9.6, which we round to 10. We now have the pattern x.x..x.x..x. The way I would do it would be to store the pattern in table; calculate the slice size (e.g. 12/5), then multiply successfully by values from 0 to n-1 (0 to 4, since we want 5 divisions of 12), round that, and then store a 1 at the rounded index values. I'm sure there are plenty of more elegant methods. - martin On 25 May 2011 22:13, Cody Loyd codyl...@gmail.com wrote: Posted this on the PD forum.. but haven't heard anything yet so i thought I'd try here as well.

[PD] Waiting an array to be finished reading
Hi all, I'm reading a drum loop from an array. While playing when i read another loop in to the array it naturaly keeps playing from the phasor's current value. How can i wait the array to be finished reading before writing the new sound file into the array ?

Re: [PD] Spectral focusing
Hi Zax, did you look into Miller's timre stamp example file? Perhaps this is also useful for you! best, P e...@mx.kein.org wrote: Hello list, After a few years of maxing I migrated back to PD about a year and a half ago and haven’t looked back. Now I ran into a stumbling block and I figured I turn to you for help: I’m looking for a way to impose a harmonic spectrum on a non-harmonic signal. I tried cross-synthesis with a harmonic signal, which is ok, but what I’m actually trying to do is to “tune” a field recording, in a way, so it can have harmonic relations to a live instrument. I played with the pvtune~ object from fftease which is nice, but the results end up sounding a bit autotune-ish. And I also tried driving a few vcf~ filters with frequencies running from fiddle~/sigmund~ but the fundamental from these objects is too erratic and it sounds very unnatural. Wishart describes in his book a technique he calls spectral focusing, which relies on lpc. He says that lpc can be set to generate a filter bank which is distributed evenly with respect to pitch, but I’m not sure I understand what he means and how it can be done in PD. lpc seems to output a set of amplitudes for the coefficients. Can I set the filters to frequencies of my choice?

Re: [PD] Waiting an array to be finished reading
You have to know the length of the array. If you know the length you know where the phasor is with respect to the end of the array. Also, if you want to write something into the array, you should do it before phasor reaches the end. Otherwise you'll have to read and write at the same time. Generally i use a different array to write to, and switch to it when phasor has finished reading the first array.

Re: [PD] When the bubbles exploded, they tickled the bath.
The question is close to some of the issues we (softday.ie) explored in our Marbh Chrios performance. Just playing a sound doesn't make any bubbles. Eventually, we thought about what a human drowning would sound like. After playing around with various patches, we decided to use a plastic bottle with a contact mic and sing through a hose, allowing the airflow of the singer to bubble the water. This contraption is now known as our Bubbleizer (and looks good in a performance). This is, of course, not the true answer to the question as sound isn't contained in the bubbles, but as a metaphor it works ok. You could probably get a similar effect by passing your sound through a set of tuned vcf~ objects controlled by bubbly ramps. /Mikael On 26 May 2011, at 12:33, Pierre Massat wrote: I guess the question isn't that simple... 2011/5/25 Pierre Massat pimas...@gmail.com Hi All!

Re: [PD] When the bubbles exploded, they tickled the bath.
I think +bubbler is just an enhanced delay that splits the sound into particles that can be played backwards, etc. (It's a very cool external btw, like the rest of the package). I tried once (to no avail, but i didn't spend enough time on this) to use vcf~ with exponential ramps, but i didn't get anything satisfying. The bottle sounds interesting, although i want to have an effect that can be used live with my electric guitar (i mainly use pd with my guitar). Is there any video or sound clip on your website in which the bubbleizer can be heard? Thank you both for your replies!

Re: [PD] When the bubbles exploded, they tickled the bath.
I solved this a couple of different ways for various projects. The rjdj Drowning Street had a bubble generator (synthetic) hooked to an envelope tracker (RMS side chain with [env~]). It works well if the pitch centre of the bubbles are close to the voice pitch, so you could use fiddle or sigmund to focus that. Another bubbling voice thing I did used slow amplitude and pitch modulation of the voice to create a Dalek type ringmod circa 8 Hz. The vibrato effect can be done with [vd~] taps, spaced in time and enveloped like a bubble generator. Interestingly, some realism can be added if you pitch shift the voice up too, since underwater the speed of sound is faster.

It makes sense relative to one or another pre-assigned matrix of alternatives... You have to say in advance what features are going to count. No pre-conception, no conception. Otherwise its novel, and a confusing jumble until some ordering, naming and searching of existing patterns has taken place. The next time, maybe then it's okay for those sensible impressions to become worthy of a symbol, like the number 42. In that case there are necessary conditions for the perception of 42 trees falling, other than the physical fact itself.
