Wow, didn't know there were more than two. Yes, Frank - I read an old post of yours where you had started some abstractions for something similar to what I want. Unfortunately, even though I have iemmatrix installed (via extended... maybe I should compile from src?), only some (most) of the objects work - there are no tilde objects in the dir though.. But out of all of them, which would I use for an audio connection grid? There doesn't seem to be a [mtx_*~] object, but this is extended 38.4 - if that object was a recent addition then I ought to recompile or upgrade. Roman, even when I try it with the argument, doesn't work - thanks for the suggestion though. Later today I will checkout the newest from CVS (or via the autobuilds) and see what I can do.

RE: [PD] Pre Loading a Delay Line
Thanks for all the great conversation!!! First thing, now that I have done some research, I am getting KS, and Waveguide synthesis confused. What I have patched up is a Karplus Strong synth, that sounds like a PVC pipe... It is not really a waveguide synth in the true sense. The initial noise burst, which comes through, is desirable in this synth, since it represents the percussive hit of the pipe end. One thing about pre loading the delay line, is getting the true sound of the recalculating line itself, without the noise pulse at the beginning. You can output the delayed signal, but it appears 20 msec or so 'late' for bass notes. I picture it similar to pulling a bass string with your finger, you are adding energy to the string, but there is no sound from adding this energy. So the string, in cross section looks like a single cycle of a saw tooth. The pickup is located someplace on the string, and starts producing sound the instant the string is released, not 20 msec later, the timbre of the sound based on the energy stored by the finger being released. What I am describing in the last paragraph is a true 'waveguide' implementation, with a pre load. (Covered under various patents etc as I discovered last night) otherwise known as a 'Physical Modeling Synth' very well described by Julius O. Smith et.al etc. etc Are there examples of 'Physical Modeling' PD synths??? mcg -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of padawan12 Sent: Friday, December 08, 2006 5:08 PM To: Frank Barknecht Cc: pd-list@iem.at Subject: Re: [PD] Pre Loading a Delay Line On Fri, 8 Dec 2006 07:49:26 +0100 Frank Barknecht [EMAIL PROTECTED] wrote: Hallo, (the early bird...) [EMAIL PROTECTED] hat gesagt: // [EMAIL PROTECTED] wrote: Yes, but that wouldn't be appropriate for a xylophone. I think it depends on the excitation mode and what instrument you're modelling whether to pass the excitation impulse directly through (or through a body formant), or only take it from the cold side of the delay where it's one period late. I think this is how you decide.. If it's a displacement that you're modelling, like plucking a bass string at the middle (antinode) then yes you want to have the delay, that's the time until you really hear anything from the moment the pick is released, the time to propagate along the string. But for struck instruments, the hammer excites the whole thing locally, and the waves spread out and travel back and forth until they fall into phase with the waveguide (delay), (Karplus-Strong), and then you want to hear the delay contents as quickly as you can, so you want the buffer to be preloaded with an image of the impulse. Hm, I still don't quite get it: In the patch Michael already plays out the excitation pulse because his pickup is next to the [delwrite~] so everything that goes into the delay is played out, especially the first excitation. The second repetition of the (filtered) excitation will arrive after the first delay period, but doesn't it have to wait that long? Because if it would come any earlier you would have a tone with a different and *higher* frequency because basically you just set the delay period to be shorter for a short time. Or am I totally off-track? I see it, in the waveguide, he sends the impulse straight through, so yes you always hear that click in the attack. I wonder. Is the optimal buffer size the size of the impulse table? Any difference in the first cycle is going to end up absorbed into the sound as a difference frequency I imagine. So, one would really want to resample the excitation so it fits properly into the first frame. If your delay is set to the right period and already preloaded from the table the problem is solved. And I wonder, what's the pros and cons of using a symmetrical impulse seed (negative and positve) vs storing only a half cycle and fliping phases alternately? It's good to discuss this, because the best implementation isn't obvious in Pd. Am I talking crap when I say that it would be nice to use arrays in a more flexible way? Of course there is [dynwav~], which I haven't played with much. Has anyone done anything demonstrative with it like scanned synthesis or something? Are you doing that here? How do you do it, I cant see it? Is that why you set the blocksize so low? The blocksize is low because it specifies the lowest possible delay time, if you have a feedback delay and through that the highes possible frequency of the delay waveguide. See Miller's book, the chapters on recirculating and non-recirculating delay lines. For a bass player the block size could be larger, though. ;) Aha OK, Duh, I see. When using 64byte blocks I definitely lose accuracy for higher notes.For bass what works out good in my experience is a hybrid of a waveguide and waveshaper, where the delay buffer is used to create a signal that has all the
[PD] RE: [offlist] Pre Loading a Delay Line
Derek, Thanks for the great exchange of ideas!!! There was a lot of postings last night that I need to weed through. One thing I realized last night is that I am getting my terminology confused. A basic KS block, the one that I have labeled waveguide, is not really a waveguide in the true sense. So the synth that I have posted really is a KS synth. One thing about pre loading the delay line, is getting the true sound of the recalculating line itself, without the noise pulse at the beginning.

The synth that I posted, does a pretty good pvc implementation. You can do what you suggest just by playing octaves on the thing... I am going to get a little more theoretical, and possibly implement an external. I got the examples to compile, but have some kind of boneheaded error that I need to fix.

When I get a free moment I will check all this stuff out at length. I'm not one for classic textbook stuff either, so I figured there was a method to your madness ;-) One way I've been dealing with this low frequency issue is by taking some inspiration from the Trautonium. The Doepfer synthesizer manufacturer recently started to make modules for reproducing this sound, but the basic idea is very simple. Take a note, and make a few octave or partial octave subdivisions. So for each note you could have two or three subharmonics of that octave which would fill in the low frequencies. In practice, this would mean setting up several KS delay lines for each excitation, but pitching them at subharmonics of the highest note. Octave divisions are the cleanest and most natural sounding, but three or four octaves below some notes means you have a slightly pitched echo rather than a tone. So half, three quarter or other divisions are worth experimenting with. Normal, musical divisions with a slight detune just high or low of the target note give very nice, rich, deep sounds. From here, you can easily side-track into Just Intonation theory and all other kinds of stuff. I just like it when it sounds heavy! good luck, d.

[PD] hd video in gem on linux
Hi, I want to use Gem to synchronize several linux machines playing high resolution videos 1440x1080 or 1920x1080. any comments on that??? At the moment I ran into some problems. 1) when I load one movie and play it with pixfilm or pixmovie (autoplay 1) it works fine, but when I want to change to another movie and send [open movie2.avi( then everything almost freezes and the speed of the gem output reduces to maybe one or two frames per seconds. (the movies are the same codec, the order does not matter, I also can't load the same movie twice.) 2) to get the highest quality I am playing around with mplayer to try some codecs. I found lavc in connection with mjpeg a working solutions, but if anyone could help me with that, would be great. (mencoder /data/chr.mov -oac pcm -o /data/chr_enc1.avi -ovc lavc -lavcopts vcodec=mjpeg) 3) please feel free to add any comments on high definition videos in connection with gem. like about the use of keyframes, preferable framerates, I searched the archieves, but all the threads seem to die after some time... marius. ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] Structures: get data dynamically
Hi list! I'm taking a look at data structures. In the attached patch I'm trying to select an init point and an end point for a sample using an init struct and an end struct. I can select this init and end point with the mouse but then, I would like to use this init and end point information for audio process. I can obtain the init point or end point value by means of pointer get, but I would like to obtain this value dynamically, that means, to obtain the value each time I change the init or end point. How can I obtain this values dynamically? Somebody has any suggestion? Thanks and regards!

The spec on glColor: http://www.rush3d.com/reference/opengl-bluebook-1.0/ch05.html#id5458953 Is there a different class that can separate colours instead of just pixes and coordinate-systems ? Every vertex can have a color assigned to it. In GEM the same color is applied to every vertex in a Geo because the interface to do otherwise would be cumbersome. You can set the color once and then every vertex in as many Geo objects as you put after [color] will be that color. It is highly recommended to place a color object before each Geo. ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
RE: Re: [PD] fmbox patch for d/l, improv
On 12/8/06, padawan12 [EMAIL PROTECTED] wrote: Personally I'd drop the freeverb. Lot's of people seem to put a reverb on their synths then get to see it's really best without it. Reverb is nearly always global effect in most cases, unless you're Phil Collins and want your drumkit to sound like each drum is in a different room. If the synth is washed in reverb too much I think you lose the focus of the sound, the sound becomes all about the reverb and not about the synth, so you lose control because you cant really hear it anymore as you twiddle the controls. I agree about dropping the freeverb from the patch, as it's really better to let people choose their own (or no) effects unless it's truly integral to the synth's sound. And it makes things more portable and usable on lower spec hardware too. However, I disagree about reverb being a global effect unless you are Phil Collins. I think this depends on the genre. Yeah totally. I was being a cock about Phil Collins, it's just that late 80's hey we can afford 10 of those Yamaha REV1 boxes so lets use them on everything that grates on me. Some tracks use reverb totally disparately to create a good effect, and honestly, there's no reason *not* to have a synth patch or entire track based largely on reverb effects - I just think it's a common mistake when building and composing with synths to begin with adding too many effects on each one, and ending up with over-dense mixes. How much reverb and what kind? That's an old favorite ;) ! I'm of the less is the new more school this week :) Specific purposes are worth remembering, like you say, the difference in where you want the best replay sound , headphones vs a club PA is a proper baffler, and as usual there's a happy compromise to seek that defines your own style. I make quite a bit of techno/house/electro/minimal, and to me reverb is almost never a global effect. I usually use it (or a synced delay) on one or two sounds in a mix which need to have a sort of floating/wash feel and lay over the top. I see, you target specific elements you want to have a reverb. I guess I do too, I mean being selective on the global reverb(s) mixes, though the aim is often to bind things together that want to be in the same space. I say reverb(s) because actually I think the best result is obtained by using two processes, one to handle the early reflections, the hardness and tightness of the reverb and one to handle the wash, but they have to work together. But the key to getting nice and tight percussion, and very clean mixes that will sound right in a a big room, is having most of your stuff totally dry with no effects at all, except compression of some sort ... Yeah agree, that early detroit and NY techno was so powerful because of it, the clubs gave the sound it's life and you could pump it up big because it was dry. I might have 8 fx tracks, and just one will have reverb, and a second delay. This assumes one is making tracks that may be played on a club system at some point. Headphone/listening music would give one more leeway. But this technique been working for me as my stuff is sounding quite good on those systems -- comparable to other stuff I've been playing out with my own stuff side by side. Note, I'm not saying put different reverb on each thing - but rather use a single reverb, but only on one or two elements in a mix. This being the case, you still wouldn't want the reverb built into the synth, as it needs to be applied in terms of the mix as a whole. Just my personal opinion. Good one. And I suppose it depends on your mixdown style and way of working too. I have grown fond of jack-rack and leaving all those processing decisions right till the last moment. Having said that there's probably room for a few more good reverb objects in Pd, things like [vdn~] and whatnot, maybe some nice convolution. Any thoughts? best, andy ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
