Re: [PD] Ambisonics for Immersive Environment
Hi Milo, The IEM's ambisonics approach (binaural or with loudspeakers) is very consistent and from my point of view very well programmed (as the programming involved Thomas, Iohannes, Winfried ) The CUBEMixer is a very nice GUI combining sub-busses, direct routing, ambisonics (for headphones and speakers), room-simulation, etc., and allows you to work like on a conventional mixing desk. We've been applying the libraries mentioned above to many artistic and scientific projects over the last view years. I really can recommend to using them, as they are pretty stable. The communication with your applications might be easily implemented using OSC. Unfortunately I don't know the libraries you mentioned (Amblib, ambipan, etc.) very well. So please check for other recommendations too :) Cheers, Markus Quoting j milo taylor [EMAIL PROTECTED]: Hi, I am bit of a newbie and I'm intending to development an immersive audio-visual environment based on a mysql / xml database of sound artists.

Re: [PD] A slightly more substantial question
Hi Ken. I haven't used the jack_transport object, and I don't know what its format is; but, assuming you can translate it into audio samples, one very simple way would be: [bang~] | [jack_transport] | ([expr] or whatever format conversion you need) | [$1 64( | [tabplay~] If you change [block~] size, then the second number in the message box would have to change too. 64 is the default number of samples per block, and [block~] outputs one bang per block. I don't know if this is necessary or not; perhaps it wouldn't stray anyway. On the other hand it might work better to make the number 72 or something higher than the block size, so you don't have gaps if it does stray... -Chuckk On Thu, Apr 10, 2008 at 4:18 AM, Ken Restivo [EMAIL PROTECTED] wrote: I'm trying to create a PD application that'll be sync'ed to jack transport as a sort of master clock.

My question is about what'd be the most efficient/effective way to sync up a tabplay~ or tabread4~ object to the sample clock in jack transport. So far I've considered the following approaches: 1) Bang jack_transport with the output of a sig~ or phasor~ object, getting the clock from jack, and use that to hit tabread4~ (I don't know how I'd do this with tabplay~ though, and performance is an issue so if tabplay~ is cheaper I want to use it). 2) Bang jack_transport with the output of a metro every n milliseconds, and calculate what sample I'm supposed to be at in the tabread4~ or tabplay~ object, and just re-sync periodically if they drift. If they aren't ever going to drift (i.e. if PD's internal sample clock is sync'ed to JACK), then perhaps this resyncing will only happen at the start of playing, or perhaps I only need to do it then. 3) Or, maybe, let's say if I have a loop, I just need to bang the tabplay~ whenever the sample clock in jack_transport divided the number of samples in the loop is modulo 0. That'd be simplest and probably cheapest, but I don't know if the clocks will drift. Will they? I dunno. I'm asking you guys when probably I should be asking the software instead, by just trying it out and determining empirically what works. But before I get too deep into it I'd like to get a second opinion on whether any of the above approaches will work or if there's some other technique I should be looking at. For some reason I suspect that this'll go really easily, but I want to make sure I'm not overlooking anything important.

If you want to play samples with a different samplerate than the one Pd and jack are using you have to to use tabread4~. tabplay~ doesn't do any interpolation or transposition. I normally never use tabplay~ except for some quick prototyping. 2) Bang jack_transport with the output of a metro every n milliseconds, and calculate what sample I'm supposed to be at in the tabread4~ or tabplay~ object, and just re-sync periodically if they drift. If they aren't ever going to drift (i.e. if PD's internal sample clock is sync'ed to JACK), then perhaps this resyncing will only happen at the start of playing, or perhaps I only need to do it then. I've never used jack_transport, but the samplerates of Jack and Pd should never get out of sync unless something really bad happens (xruns etc), and then you have other problems. However what can get out of sync is the notion of: What time is it? Pd itself doesn't have a timeline built in, so how to deal with a global clock very much depends on what your patch looks like. Example: Jack transport can do a rewind to the beginning of a piece. A Pd patch however may not have a beginning, it might just run a process which gets modified. What should such a patch do with a rewind order? Assuming you have a Pd patch which has a beginning and which at the beginning plays a sample of 2 seconds length with tabread4~ and vline~. Now jack_transport moves the system to a time 1 second after the start of the piece. Then you either can ignore this and not play the sample at all, or you restart the sample, but with the vline~ at the position it would have 1 second after the beginning. This of course requires a slighty different patching style than if you would just ignore it - as you'd have to patch your sample player in a way that it can always start playing samples at every possible time.

Hallo,
marius schebella hat gesagt: // marius schebella wrote:

That's only because it's a generic helper for dynamic patching. You
could of course also just do your dynamic patching the traditional
way.
and I wonder if there is an overhead from additional send/receives?
There are no additional sends and receives in nqpoly4: It handles
messaging from the outside through direct connections with in/outlets.
I doubt that it makes much of a differnce anyway.
An alternative with Lua might be to write polyphonic pdlua objects.
A quick example is attached simple [linebuffer] which just draws many
[curve 2]-like lines with optional aging. It can easily handle several
thousands of lines. (Requires luagl, rename suffix for newest pdlua)

Re: [PD] lua scripting for pd objects
Hi Marius, i've used py and dyn~ in combination for such stuff many times. With that many objects it makes probably sense to put the abstractions in subpatches (e.g. 30 subpatches with 100 objects each) as pd has problems with many objects in one canvas. gr~~~ Am 10.04.2008 um 18:10 schrieb marius schebella: hi, i need to create a lot of instances (let's say 3000) of a gem abstraction. each instance has to hold it's own variables, so it is difficult to work with repeat.

[PD] memento, rrradical, sssad?
Hi Frank, list! I'm getting into memento because I'm trying to implemet a state saving utility for my tr-909 emulation patch. I've taken a look to your RRadical Pd tutorial and I have use your examples from Pd extended help. But looking at Polywavesynth patch by Phil Stone, I've taken a look to his state saving stuffs based on sssad, and that looks pretty much easy and suitable for my purpose. So, now I'm a little bit confuse with so many libraries. I would like to know what's the purpose of each of this libraries (memento, rrradical, sssad), its applications, advantages, and inconvenients, and which of this is better for my purpose. Another question is about OSC libraries. I've used oscx succesfully but I've seen Polywavesynth used Mr Peach OSC objects (which seems pretty usefull). What's the difference between both? My head is full of apparently-same-purpose libraries!!!
