[PD] [ngrid]?
Hello all, So I posed a question about calculating triangles made by intersecting lines is a pentagon (thanks for the help Mathieu), and now that it is done I want to easily control the 5 vertices. I remember using [ngrid] at some point, which is [grid] but with multiple vertices... exactly what I need. Googling turned up this: http://puredata.hurleur.com/sujet-1378-designing-surround-sound-mixer which basically says [ngrid] is in the ix library. Well I can't find any mention of ix library anywhere... Does anyone know of this library/[ngrid]? I just installed extended 0.42.5 fresh thinking it would be in there...but nothing.

One of the channels deal with, yes, granular synthesis (thanks to the nqpolywrap object) using long samples from the recordings (from 20 to 60 seconds), but what makes them interesting is the range that I allow the grains to be selected from. i have never heard of this object (i use pd vanilla, with only a few externals most of the time, so it is probably included in extended?) how are the grains selected? in my granular patches i have only used position+random jitter so far, but more complex patterns, or a mixture of grains from different positions might be interesting too. maybe a good idea for a new granular patch... The second channel has another really simple synth based on two phasors, plus buckets full of reverb and some samphold to add dirt. that was probably what i thought was the 'resampling effect'. (not completely wrong though ;)) The third channel is a so-called bass where I generate a random table with six values, and play them with the Monome so everytime I generate new values for the table I get new notes I'm not aware of, therefore I have to think really quick. did you generate the values 'manually' on demand, or by some kind of automatism (a metro for example)? i think both could be quite challenging, while the latter variant provides less control for the human performer... Yeah, that's it. I tried to keep it really simple to avoid overwhelming my processor and to be able to control as many parameters I could with the devices. I don't know if it was clever, but it was my own way of solving it... large sets of parameters are always a problem, and some kind of automation might be necessary to deal with the complexity. i think the concept of 'scenes' can help a lot, like switching (or crossfading) different pre-programmed sets of parameters. bis denn! martin ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Have a look at room_sim_2d from iemgui or the attachment.

Re: [PD] Need Help Understanding pack
Here in belgium, in dutch, we also say other right/left, but since french is one of our languages, that could be the origin, on the other hand I dont really believe its language related: from inside a head your left eye is not the same as from outside the head (like face culling in OpenGL,...). Instead I would think its just a softening for pointing out a mistake through use of humor. 2011/2/9 Mathieu Bouchard ma...@artengine.ca: On Wed, 9 Feb 2011, András Murányi wrote: It's not a brain damage, but a neurological thing.

Re: [PD] Sigmund~ and tracks.
Could you make a simple example patch that demonstrates the rhythmicized/pulsed result that you don't like? Without knowing exactly what's going on in your patch, my first question would be whether or not you're smoothing the frequencies and amplitudes with a [line~] or something else. Maybe sudden changes due to fleeting tracking errors cause glitches that pulse in sync with the analysis period? With a violin as input you should get a reasonable enough spectrum to get stable harmonic tracking with a window much smaller than 65536. The low G on a violin is 196Hz, so the bin spacing you'd get with -npts 4096 would give plenty of resolution for catching multiples of that fundamental and higher ones, and only 92ms of extra delay. The hop setting you choose will just affect how often the information is updated (and CPU usage too). You should expect to deal with some temporary tracking errors during moments like attacks, where components of the spectrum won't be in a perfectly harmonic relationship. Going beyond 131072 points using Pd's built-in mayer_fft() has given me garbage as output in the past. Maybe someone else knows something about this limitation?

The viola is playing long(ish) single notes between 1-3 seconds and the problem I am having is that when sigmund processes the partials they come out rhythmicised/pulses which seems to be a combination of the 'hop' and 'npts' settings. As the values for hop and npts get higher the pulses get longer up until my current huge setting: [sigmund~ -npts 65536 -hop 65536 -npeak 48 tracks] when the partial frequencies balance out into steady lines. I have also tried -hop 131072 which works too but trying that with the -npts completely locks pd. The problem I have now is that there is a significant delay between the beginning of the processing in comparison to the viola and worse still is the overlap after the viola has stopped playing. Also the viola notes are indeterminate so I can't just set a cutoff to sync the two together. I could use the input of the viola to gate the tail of the processing but I am currently using a combination of [env~] and [lop~] so that as the performer plays his amplitude controls the processing in reverse, so when he's loud the processing is quiet etc. I suppose I can add another layer on top of the end I am aware that the gap between the two sounding events is caused by the huge window sizes I am using and that there may well be no way around this to get the kind of sound from the processing I'm looking for, i.e. without the pulses, but I am wondering if anyone has any tips and tricks I can apply to try and bring the two sounds, viola and processing, closer together. Or ideally some way of achieving the smoother processing with lower npts and hop settings. This is for a live performance btw.
