hammerfall on osx
by Alex from Idoia 10 Apr '03

10 Apr '03

Hi list, I know this is the second time I send this email, but I cannot solve my problem and this is now driving me crazy. So if that time nobody has a solution I will give up. I have a Mac G4 867Mhz, it has no built-in audio input. A Hammerfall DSP has been installed properly. Now when pd starts, the terminal gives the error -99999, and there is no audio in pd at all. I think their is a conflict with the DSP of the card which take care of the audio latency, but the interface to deal with the buffers of the card has disappear with OSX(unless I don' t know where to find it). I know that the error -99999 is an audio problem, I have tried to start pd with r -48000 and even r -22050, but it is still the same. I have also tried different audiobuffer but I am not very confident with the value to use. If anyone has any other idea to solve that problem, it will be very much appreciated. Thanks again. Alex

Re:[OT] How do your performance environments looks like?

Hi Maurizio, I am using pd for live improvisations and for quick prototyping of sound effect programming. For the performances I use 2 main patches. One is a recursive pattern sequencer. It can run and loop a pattern, but every step can trigger an time scaled instance of that pattern. Up to 2 levels deep. I tried with more recursions, but that didn't give a useful result with the processor power I have available. It could be a way to make granular textures though. The patch has 4 pattern sequencers running independently. The sounds are made with csound~ objects, which also does the scheduling of the recursions. (I am just giving it score lines) Control is done with a doepfer midifader box, the regelwerk (which also as a buildin patternsequencer, and is what got me started using patterns). And with a forcefeedback joystick. The forcefeedback is used to shake the stick for every sound/event in the primary pattern. The trigger is used to play/ add notes to the pattern. Topbuttons select which of the 4 patterns to work in, the hat is sed to delete events. The x and y and z (twist) axis of the joystick cntrol the sound. I am continously tweaking this patch and the csound orcs and scores. After every performace I change it a little bit. But it is slowly getting to be a "real" instrument. I still want to add a kind of variable resistance using force feedback to the joystick, to create zones or ridges in the physical response. (Actually I would like to work with a 6 degree of freedom haptic interface, but those are very expensive, they are used for remote surgery and NASA) Output is to my mixer with has nice parametric eq and then back to some effects in the pd patch. (tempo based delay, shifts, fm distortion) The music is some kind of abstract techno? I think it has a beat, but most people can't/won't dance to it. The other patch I use, is for combination with accoustic piano. I have just started it. It used artificial neural nets to seperate the input and send it to various long (1 minute+) delay lines. Eventually it is supposed to work with multiple inputs so I can use it as an music controlled effect device for enseble improvisations. I wanted to get away from having to use controls at the same time as playing an accoustc instrument. I have done things usng analog gates and effect processors for esemble, where th playing triggers effects on the _other_musicians, and you have no control over the electronics on your own instrument. Although I might use the joystick in this context. A racing wheel attached to the piano will look better, almost bought one, but not enough controls. The music is "free" electro accoustic music. (I am practicing a score I wrote right now, so it is not free all the time) regards Gerard pd-list-request(a)iem.kug.ac.at said at "PD-list digest, Vol 1 #363 - 12 msgs."r[2003/04/09 14:45] > Message: 10 > From: Maurizio Umberto Puxeddu <mauriziopuxeddu(a)yahoo.it> > To: Pure Data mailing list <pd-list(a)iem.kug.ac.at> > Date: 09 Apr 2003 16:34:16 +0200 > Subject: [PD] [OT] How do your performance environments looks like? > > Hello. snip > For example: is there people using graphic tablet or working with > musicians which uses graphic tables as control devices? > Do you/they use them =C3=A0 la caospad?

No midi as root
by Allan Baker 10 Apr '03

10 Apr '03

Hello all, I am running pd on Debian with a 2.4.20 + preempt + lowlatency kernel and the alsa drivers. I didn't add the capabilities patch because I hadn't heard about it. I struggled compiling the kernel and am hesitant to go through it again, as what I have is good enough for now. My problem: When I run pd as root (to use -rt) I have no midi. Everything works well when I run as a user. As root, everything works except for midi. I assume that I have missed something simple. Any help will be appreciated. pmidi -l gives Port Client name Port name 64:0 External MIDI 0 MIDI 0-0 65:0 OPL3 FM synth OPL3 Port and pmidi -p 64:0 foo.mid plays the keyboard. TIA Allan

Re: [PD] windows 2000 latency?
by Herr Reinhard Gretzki 09 Apr '03

Hi, my Win98SE, pd0.35-1, SBLive, kXDriver(ASIO) Setup has a 60msec latency as measured with MSP's latency patch. Same setup except kxDriver(MME) is about 100msec. I would be VERY interested if there are other people out there with a similar setup that have better figures for ASIO latency...i think 60msec is kind of worst you could get... Under Linux 2.2.18 on the same Computer i get 10msec out of the box. That can be brought down to 6msec if i use fifo scheduling (-rt switch). However no low latency- or preemptive kernel patches applied. Should be better with them. I've been told that low latency under windows is a matter of good designed cards like the RME Hammerfall or HDSP ones...under linux you can get away with consumer cards as you can see with my figures.... regards Reinhard

Audio breaks up
by Eliya Gwetta 09 Apr '03

09 Apr '03

Hi, I've downloaded PD few days ago. Well, I cant use it with asio, and I cant play a regular sinus clear. My sound card is mAudio Audiophile 2496. Well, when Im writing 'pd -asio' on the console window, it runs PD but stucks my whole system(Winxp Pro). When Im not running the asio, but I use the -audiobuf, I can expand the buffer size only to 100. and even then, when Im creating number>osc~>dac~ the audio isnt smooth. It always cracks up and there's latency. what should I do. I'd really appreciate it if you answer me. You can send your answer directly to my email: funkman14(a)hotmail.com Or contact me through the ICQ at the number: 40924225 Thanks, Eliya.

[OT] How do your performance environments looks like?
by Maurizio Umberto Puxeddu 09 Apr '03

09 Apr '03

Hello. If this question is too OT please pardon me and answer privately. I'm posting here because I don't know a more appropriate forum. I'm using PD quite regularly to improvise and partially to do traditional composition. I'm also writing an application to be used as performance environment because I don't like to use PD for that. It is designed and evolves to fit my own needs but I think I will never release it. It would cause an additional amount of work that I don't want to do. I'm focusing on play and composing things that I like and find a compromise between changing the technology and using the technology and it takes lot of time. Here I cannot compare my advancements very well because there is no one to talk or play seriously with, with the sensitive exception of my teacher who has very a different approach and skills from me regarding technologies, computers and programming. He uses mainly a ChaosPad, multieffect box, CD player, guitars, mics and other sounding objects. I like him very much as musician but I spent my energies in a direction last years and would like to keep on that road until the end. I also live in a island (Sardegna) and cannot easily meet other people. For example: is there people using graphic tablet or working with musicians which uses graphic tables as control devices? Do you/they use them à la caospad? Use more sophisticated controls? Are someone developed more evolved widgets than [grid]? What kind of music can you make with that? This is also very important. Not the "genre" per se but the kind of musical operations you do. Thanks for your patience. Your answers will be very appreciated. I would also like to share development efforts and ideas with other developers or musicians with programming abilities if there is some agreements on the result to achieve as I still believe in open source. I will try Sarlo's GrIPD next week but I think it is going in a different direction than me. Maurizio Umberto Puxeddu.

RE: [PD] windows 2000 latency?

And here I guess would be the problem with windows. I get much, much better performance with windows 2k than I ever did with win98 (I keep up to date on all service packs and updates). Latency for me has always depended on the soundcard and the drivers, so for the original post, my initial reaction would be to look at the built in soundcard on the laptop. Make sure your Bios is completely up to date for your machine. To be honest though I'm not sure you are going to be able to get an acceptable latency with the built in sound. You may want to look at other laptop sound options. m. > -----Original Message----- > From: Peter Lundén [mailto:plu@tii.se] > Sent: Tuesday, April 08, 2003 7:46 AM > To: dmerrill(a)media.mit.edu > Cc: pd-list(a)iem.kug.ac.at > Subject: Re: [PD] windows 2000 latency? > > My expericen is that Win 2000 is the worst version window when it comes > to latency. Win XP is much better or even Win98.2 has better performance.

windows 2000 latency?
by dmerrill＠media.mit.edu 08 Apr '03

08 Apr '03

Hi there - What kind of latency should I expect out of a windows2000 machine running PD? I measured an impulse going through my laptop running PD, with the following patch: adc~ -> dac~ and it took about 224msec. When speaking into the microphone, this "echo" is really noticeable. My laptop is a Thinkpad pentium750, 256MB, with the built- in soundcard.. Is there any way to cut this latency way down? I'd like to get it down to no more than 20msec. Or do I need a faster machine? Or Linux? thanks, David Merrill ------------------------------------------------- Media Lab Webmail http://webmail.media.mit.edu
