Hi again martin, the best solution is about using real guitar effects, your sound will be better, I know it from experience, and try to use a unix OS instead of xp, good luck. patco <hello Martin, You might need other audio drivers to reduce latency, <like asio4all, but I've never heard of anyone that <has been able to reduce latency as well as a < unix operating system does with <OSS drivers (which seems to be the fastest one) <patco --- Martin Dupras <martindupras(a)gmail.com> > I'm trying to use Native Instruments' Guitar Rig software to play alongside > PD on my windows XP laptop (P4 1.7GHz, 768MB ram, cardbus pcmcia card and > MultiFace external interface.) > > With PD only I seem to be able to get a stable 23ms latency. > > With Guitar Rig only I get 3ms. > > With both I simply can't get any lower than 46ms, and that's not even stable > (I often get zipper noise.) > > And for the record, the setup is > > guitar -> input 3 (which is the input GR is using) > output 3-> input 1 (which is PD) > > To make a long story short, I need as compact as possible a system for a > performance I'm doing abroad, hence the need for Guitar Rig. > > Any advice at all would be appreciated.

Help with latency: PD on XP with Guitar Rig and Hammerfall HDSP
by Martin Dupras 03 Feb '06

03 Feb '06

I'm trying to use Native Instruments' Guitar Rig software to play alongside PD on my windows XP laptop (P4 1.7GHz, 768MB ram, cardbus pcmcia card and MultiFace external interface.) With PD only I seem to be able to get a stable 23ms latency. With Guitar Rig only I get 3ms. With both I simply can't get any lower than 46ms, and that's not even stable (I often get zipper noise.) And for the record, the setup is guitar -> input 3 (which is the input GR is using) output 3-> input 1 (which is PD) To make a long story short, I need as compact as possible a system for a performance I'm doing abroad, hence the need for Guitar Rig. Any advice at all would be appreciated. Thanks. - martin

Re: [PD] gemmouse/OSX (multiple pointers)
by Hans-Christoph Steiner 03 Feb '06

Well, with a proper [hid] object and a proper HID implementation, you can connect to as many mice as you can plug in. Microsoft did a very stupid thing with their HID implementation: the OS locks all mice and keyboards for exclusive use, so this won't work on Windows. But on GNU/Linux and Mac OS X, you can use as many mice, keyboards, joysticks, etc. as you want right now. As for CPNmouse, if it has a decent API, it would not be hard to write an Pd object for it. .hc On Feb 3, 2006, at 1:15 AM, Julian Sorrel wrote: > Speaking of [cursor], has anyone written an object that takes > advantage of the CPNmouse windows driver ( > http://cpnmouse.sourceforge.net/ ) that enables multiple cursors? > > tacitdynamite > > Hans-Christoph Steiner <hans(a)eds.org> wrote: >> I know very little about [gemmouse], so I couldn't tell you.

gemmouse/OSX

Hello Hans, I was wondering if there is a way (or a Gem version) where "Gemmouse" object works properly on OS X (pd-0.39-2)? I looked at the PD-List archive and found your message bellow. Anything new? Thanks. Carlos Caires On Sat 30, 2005 Hans-C Steiner wrote: I plan on writing a [systempointer] object which would just return the coords of the system pointer at all times, as well as button press coords. It would be a general Pd object that would do what you want, but alas, its still on the todo list. Feel free to beat me to it ;) .hc

shell object for Windows
by chris clepper 03 Feb '06

Does anyone have or know of a working shell object for Windows? I suspect it requires minGW to compile and that or Cygwin to run. I have the latter, but no minGW setup. Thanks cgc

OK, thanks Victor. I added the path to pd_039_2_test7 to the Path environment variable, started a "Command Prompt", navigated to C:\Program Files\Csound\examples\csoundapi_tilde and then started pd from the command line. This works well and has the advantage of letting me see the stdout and stderr output as well. Then I wrote a batch file to do it all by double-clicking: cd C:\Program Files\Csound\examples\csoundapi_tilde pd Thanks again for your assistance and the external.

csoundapi~
by Victor Lazzarini 02 Feb '06

02 Feb '06

I realised now that this has not been included in the release notes, but it's probably the most important bit of the Csound5 distribution for the PD community: Csound 5 includes csoundapi~, a PD frontend for csound in the style of the Max/MSP csound~ (which is based on csound4). Csoundapi~, unlike csound~ for PD, uses the csound library and API. It is multi-instantiable and provides many facilities for controlling csound. You will have access to the 1000 or so opcodes that csound provides (and that wonderful orchestra and score language that we all love :) ...).

hallo, thanks for the hint ; Gem was broken in the installer, so exchanging Gem.pd_darwin with the built from gem.iem.at fixed the problem.
