Re: [PD-ot] how low (latency) can you go?

Mathieu Bouchard a Ã©crit : > When the latency is changed, the musician has to retrain to a > different compensation delay, and that's more tiresome than not having > to retrain. Hello? Seriously, it's not really a problem to have any amount of latency (even one million year) when there is a single musician. The problem is about how allowing several players with different delay time to play all together. This problem has been almost resolved with minimizing the travelling data amount with system like netpd. Also, there are some music style based on latency between different musicians, like the pygmee's traditionnal songs, or some dadaist musical pieces. Also when you have to play guitar with speakers at more than twenty meters from your hear, you'd better play something like David Lynch, than a paganini caprice. Who are those musicians that aren't able to play something different when the conditions aren't corresponding, to play the music style they were planning to? Who are the people that want musicians to play a kind of music, and not something else, in conditions that makes the music style so difficult to play? In all case those people are really tiresome.

network problem with pd / [list-fifo]
by Roman Haefeli 18 Dec '06

18 Dec '06

hi all netpd's major problem is the occurence of many dropouts in certain situations. one reason is the way how all (at least all i know) network related objects in pd handle buffer overruns. when the buffer of a network object is full, the whole pd processing is stopped until the buffer gets emptied again. buffer overruns could be avoided in userspace, if these object would output their internal state. it would be already quite helpful, if there would be a second outlet, that outputs a bang when ever the buffer is completely emptied (like [textfile] or [list-drip] and other object do). with this information it would be possible to build a patch, that uses maximum bandwidth without ever getting dropouts. the above concerns at least [netsend], [netserver]/[netclient] (from maxlib) and possibly the objects from mrpeach. as a crude solution to limit bandwidth in netpd, i made the attached abstraction [list-fifo]. i am not sure, if it is a suitable name. @frank if you think, that fits into your list-abs-collection, feel free to add/modify it. roman

Abstraction [define]
by Luke Iannini (pd) 18 Dec '06

18 Dec '06

I just thought I'd propose an idea I had driving home : ): As a supplement to the subpatcher functionality, what about having a [pddefine] object that took a name as its argument, and a patch built inside would then be callable within the parent patch patch, acting functionally equivalent to an abstraction (i.e. arguments, etc). The advantage of this would to simplify distribution of pd-patches that would like to use abstractions, but don't want to have to include 15 files for one program. It would also be great for "1-off" abstractions that aren't usable elsewhere, but are needed multiple times in the same patch. Anyhow, I can't write it, so I guess it's just an idea for able devs to consider. Luke

What's the output of [midiin] when you send clock to PD? I made attached patch for winXP, maybe I can help you adapt it for Linux.

adding the Pd lists to GMANE
by Hans-Christoph Steiner 18 Dec '06

18 Dec '06

http://gmane.org Does anyone have any objections to adding the Pd lists to GMANE? It would be an easy way to add a forum-like interface to the Pd lists. And we would have to maintain or pay nothing. .hc ------------------------------------------------------------------------ I spent 33 years and four months in active military service and during that period I spent most of my time as a high class muscle man for Big Business, for Wall Street and the bankers. - General Smedley Butler
