Is this a PC-only issue? I easily get 4 720p24 clips on a dual G5 and at least 3 1080i60 ones.

That should be a reasonable solution and I haven't seen the same thing happen here with turning the gemhead on and off. I do have a problem where the first time I turn on rendering with a DirectShow or Quicktime object the output is like one frame every few seconds. Turning rendering off and back on makes everything run at full speed. Maybe try your DV clips as Quicktime rather than AVI? > I could use a slightly slower framerate...

Re: switch between multiple signal outputs

(i'm curious) I can't speak for IOhannes, but sometimes when sending patches to friends who are musicians not programmers, it's nice to have something that works well on Miller's pd for which there is an easy installer with a good set of built in externals and no complications. This is preferable to teaching a windows user how to compile and install from fifteen different sources on the net, when they already have so much trouble just with outlook express and their usb midi hardware.

GOP datastructures sequencer
by Chris McCormick 19 Dec '05

19 Dec '05

Ey, Been playing around with data structures. This is a GOP datastructures sequencer dependent on pd 0.39-2: http://mccormick.cx/viewcvs/*checkout*/s-abstractions/s-varseq.pd?rev=1.2 This might not be particularly original - I'd really like to hear if someone has done this already and done it better. My goal was to create a generic sequencer type of object, which I could create with a variable number of 'ticks' in it. Create it with two arguments like: [v-seq 2 4] This will create two sets of four 'ticks', each one of which you can vary (by dragging). Connect a number box to the inlet and outlet to observe how you can select a particular 'tick' to see it's value (whatever you have dragged it to) at the outlet. There appear to be a couple of bugs with this - you can't move the object once you've created it or the 'ticks' stay where they were and only the box moves, and you can no longer edit it. Does anyone know how to solve these bugs with GOP datastructures? Best, Chris. ------------------- chris(a)mccormick.cx http://mccormick.cx

GEM dev distribution
by Brad Kligerman 19 Dec '05

19 Dec '05

Hi all/ I'm frustrated by not being able to completely and correctly compile the latest and the greatest GEM and certain other extensions I use everyday to build GEM patches. My efforts have been sadly chronicled on this list for the past several months. So I'm wondering if it wouldn't be easier if I used the same distribution as GEM's devel people?? 1/ Is it correct to assume GEM etc... will compile correctly if I'm using the same distribution as the people developing it; and 2/ which distribution do most or all of GEM's developers use (though I think Debian is the correct answer to this one)? I'm currently using Fedora FC4 for both desktop and server apps, and I'm otherwise happy with it. Thanks /Brad.

by João Miguel Pais 19 Dec '05

19 Dec '05

Hi, following questions about iemmatrix: - I was looking for the documentation, have the files from cvs but there's no help file for mtx_*~. Are these the most current ones? - where is it possible to find the latest version of the dlls? I look ed through the archives, but it wasn't possible to find those. merci, Joao -- Lugostr. 14 79100 Freiburg i. Br. Deutschland +49 (0)761 7074997 jmmmp(a)arcor.de
