Hi Karl, this is only partially true, I'm using Pd with standard (Rme) audio drivers, of course ! And Karl, what about a pd porting to OS X when it will be ready, aren't you working on Apple hardware ?

signal-addition
by smedge 05 Mar '01

05 Mar '01

hi is there an object (beside dac~) to which i can send lots of signaldata-outlets, which are simply added. if i write dac~ into an abstraction i can call it as often as i want, all inlets of all abstractions are added at the dac~-object. but i would like to send two (and much more) signal-outlets to an array without the need of connecting with lines. thank you. marius.

Hi all, in my experience Pd works much better on Win2k than on Win98. Using Asio and Rme Hammerfall I could obtain good latency (under 50 ms) with Cubase. Under Win2k the best should be to use a multiprocessor Pc. And remember you have to carefully look at the interrupts (perhaps installing the standard PC Hal helps). Consider that you'll not be able to achieve good results using the SB Live with standard drivers and Pd (I tried). With The Hammerfall and Pd the latency is acceptable but not ideal. Don't know about the Terratec. We'd need the Asio interfacing but is it worth ? Wouldn't it be better to use Linux or (possibly in the future) Apple Mac OS X ?

writing pd addons?
by nullpointer 04 Mar '01

04 Mar '01

Hi All, I'm running PD on win 95 and all is fine (cept my multichannel output but thats another story) I want to know how easy it would be to write a set of pd objects to deal with screen output using my own routines.. similar to what gem does but mouch simpler...(just 2d draw stuff) I am a reasonably experienced C(++) Coder and i'm using MS Visual C++ 5. I'm not sure where to start though.. I've examined the Gem code. but to be honest it's just too huge for me to get my head around it, I need to be able to start off by creating a really simple library of a few objects that i can use to commmunicate from pd to my own screen display routines.. (its more the management of the system ,i.e should i be making dlls or what and how do I link with the pd librarys.. m_pd.h? e.t.c. If anyone had a bare bones example they could show me I would be most appreciative. Can anyone help....?

analouge input controller
by Christian Klippel 02 Mar '01

02 Mar '01

hi all, i have made an analouge input controller box that hooks on the parport. it provides up to 88 input chanels with 10 bit resolution. it would be nice if someone could adopt the driver i have made for jmax to pd, i think this is a usefull device. you need electronic experience to build this. you can find it on my site in the electronic section. ( http://mamalala.de/files/electronic.html ) greets, chris -- visit me at http://mamalala.de ICQ-> NICK: chrisk ->UIN: 108069244 (not always online.....)

Now that we have a FAQ, I humbly re-petition the assemblage for a Freshmeat entry. Also: what's the deal with the license on the qlist source code? I haven't heard an answer yet. (jfm3)

pdsend and pdreceive for Irix?
by Martin Dupras 02 Mar '01

02 Mar '01

Hi, I am quite new to PD, having been mostly a jMax user for the last year or so. I'm running PD successfully on Irix 6.5. I need to receive messages sent from a web form. Did anyone successfully compile the pdsend and pdreceive linux utilities on Irix? That would make the above considerably easier. I would be as grateful if anyone has good pointers or insight on how to do the above. Thanks! - martin

Latency in Audio
by claudio 02 Mar '01

Hi, I've some problems with the latency in PD's Audio in/out. I use PD under Windows ME and Win2000 and works very well (in Win2K midi timing is more stable), but I've some problems to use it for my works in real time. I must use it for very little patch (filtering, ring modulation ...), but the latency is about 300ms. I run it on a Athlon Th. 800 Mhz, 256 Ram, HD IBM 30Gb, audioCard SBLive. How can I reduce the latency? I will buy a Terratec 24/96, so I hope to reduce the latency time. Can someone give me some councils? With my best regards Claudio Scozzafava
