Hi all, after replacing my fedora with debian again :) I compiled gem 0.90 from cvs and everything went fine. But there is one really strange behaviour. Once I open a pd/gem path it doesnt show anything. Sometimes the blue square help patch works but usually there is nothing to see - and there are no error messages. It seems to be something linked to Direct Rendering - if the console gives a "Direct Rendering enabled!" there wont be anything shown, if it doesnt, everything works fine. But is there a way to control the Direct Rendering? glxinfo says that my geforce 5700 can handle direct rendering. I compiled gem using the nvidia glx 1.0.6111.1 driver for my geforce 5700 card. Does anybody know something about this? thanks in advance, cheers. christian

Hi again, I tried a bit more to get gem running and if found out that it renders everything correctly when the gemwin is created the first time. Once the gemwin is created the second time after destroying the first gemwin the rendering output wont work anymore. ??? christian

hi christian,
...if I remember correctly, this problem just recently became apparent for me, too...but I haven't had the time to track it down: I'll put this higher on the priority to-do list :-)

for me, too...but I haven't had the time to track it down: I'll put this higher on the priority to-do list :-)
and for me the same behaviour is true sometimes too... and i haven't had the time to track it down either....
anyhow, we'll see

When I bang those objects, I obtain :
[metro 10] [* 10] => 20000
[realtime] => 21273
[cputime] => 578.125
Test it yourself. What do you think about this results ? Witch one of them can I use for have the exactly reflect of the reality's time?
Thanks .sr

hello,
time and date objects from zexy would give you the exact time of the hardware clock. so they can be trust.
cputime looks the utilisation of the computer cpu, it can't be related to the curent time.
it looks strange that realtime is not 20000 it's almost the case on my computer : 19991.2. (0.38.7 on linux).
have you tried a metro 20000 (and select 1)?
cyrille
P.S. could you use a [t b b] where connection order does matter.

Hi list,
Thanks to Cyrille for his answer. I have two problems, the first : I'm not able (because of my bad math level) to make a simple patch for have the output time in ms between to bang with the [time] object from zexy library. Is some one can help me ?
The second : I don't understand were come the near 1.5 % error between [realtime] & [metro] objects. It seam to be different from a computer to another. Maybe a latency problem... mmh...? I do this simple patch for test several [realtime] objects, and none of the 10 objects give the same result. Do you now why ? Thanks .sr
Sorry the patch is here.

The second : I don't understand were come the near 1.5 % error between [realtime] & [metro] objects. It seam to be different from a computer to another. Maybe a latency problem... mmh...?
well, messages are handled at a "single instant of time" each DSP-cycle (which is approx 1.5ms with 64samples @ 44.1kHz) of course the "single instant" is not "at once" but takes some time itself (due to the nature of sequential CPUs).
[realtime] basically measures the number of CPU-ticks between 2 bangs. running an operating system on your computer might use some ticks now and then; when your systems eats more ressources, the [metro] might be called a bit later, resulting in jitter.

Thanks Johannes ,
I need one way to measures the elapsed real time of a recorded sample from [adc~] (beetween the "start recording" bang and "stop recording" bang), in way to use this value for read this sample with [tabread4~]. Can I use [realtime] for that ?

use [timer] for this. as the "start" and "stop" recording buttons will be synchronized to the dsp-tick this will give you more "accurate" timings than what you want. ([timer] is somewhat sample-aligned while [realtime] is not)
