well, I thought you were disucussing here and reaching the conclusion that [timer] is the one to be used to calculate this...<br>

timer and realtime compute 2 different things (logical time and real time). i don"t know what your want.<br>
<br>
what i don't understand is your intention with the spigot in the patch.<br>
<br>

<br>
So you mean this result is actually inconsistent? And the implication is that it is not going at that super fast rate at all? Please help me understand better about how to measure this.<br>
<br>
thanks<br>

hello,<br>
<br>
i don't understand your patch.<br>
<br>
using [timer], a delay 0 will give a 0 delay...<br>
logical time will always be consistent.<br>

ok, so the metro at 1ms is because I'm using extended.<br>
<br>
as for the minimum time pd can process and send data, what's the final word on it?<br>
<br>
something like 1.4013e-45 ms?<br>
<br>
cause that's a lot more than an audio rate at 44.1khz :)<br>
<br>
I thought there was a limit control rate that was below the audio rate, but curiously it can go over.<br>
<br>
1 sample at 44.1khz gives us 0.0226757 ms, and I was able to send bangs at 1e-06 ms, according to [timer]<br>
<br>
check my patch attached, based on the one that was sent here on the thread.<br>
<br>
thanks<br>

hello<br>

this patch show the same behaviors for a delay based metro and a [metro].<br>
(both can do faster than 1ms period)<br>
<br>
<br>
You're right. More recent versions of Pd (>= 0.45?) have an updated<br>
[metro] that supports many more ways to specify time and the restriction<br>
was lowered. However, the [metro] in any available version of<br>
Pd-extended is still limited to 1ms.<br>
<br>
sorry, i was not aware of this old limitation.<br>
<br>
<br>
I don't understand why you use [realtime] and not [timer] to illustrate<br>
your point. [timer] gives you consistent values (logical time) while<br>
[realtime] is very jittery and shows just some random value depending on<br>
the current cpu usage and probably other factors. When you render a<br>
soundfile, the logical time is actually the one that matters.<br>
<br>
yes, for things that stay in pd, logical time is better.<br>
but if you want to send midi note, [realtime] is more related to what happens.<br>
it's just the way i understand the original question.<br>
<br>
