    I connected the output of my soundcard to it's input, and it makes a great difference.
    Via microphone I get a latency of 533 samples (12.08 msec), via cable 440 samples (9.97 msec)

    My Soundcard is set to 64 samples, pd delay to 5 msec. Smaller delays on pd have no influence.

    My soundcard has the option to set the latency to 48 samples. Doing that, the measured latency increases. I tried a [block~ 48], but that didn't change anything.
    Isn't it possible to set the latency of the soundcard to smaller values than 64 samples?

    Thanks for reply.

    OK, just to be shure:
    Do you mean, I should plug the cable from the output of my soundcard directly to the input?

    Hi,

    beeing busy with a live looping mechanism, I need a patch to measure the latency of my system.
    I've found the roundtrip latency tester: http://www.pdpatchrepo.info/patches/patch/92

    It works well under two conditions:

    1. A microphone is plugged in and placed directly in front of the speakers.
    2. There is no loud noise in the background.

    Both conditions might be problematic in live situations, especially the second.

    My question is, if there's any other possibility to measure the latency?

    Your patch works. It changes the fill color to blue and the outline color to orange. The fill color is used with setting the view of the array to bar graph, which is an extra option in Purr Data. To get this extra option your radio button needs 8 buttons instead of 6.

    By the way: I didn't know colors can be changed by name. Is there an overview which names might be used?

    In Purr Data arraydialog needs 8 arguments. For example this would work:
    [; array1 arraydialog array1 100 $1 0 5 5 5 5 (

    Does anybody know what the 4 extra arguments are used for?

    Here is the source code, but I couldn't figure it out:
    https://git.purrdata.net/jwilkes/purr-data/blob/master/pd/src/g_array.c
    lines 595 - 791

    Hi,

    I'm searching for a message, which can be send to an array, to change it's appearance from bezier curve to bar graph and vice versa.
    Does such message exist?

    And in general:
    Is it possible to find out, which messages are exepted by an object? I've been looking through the source code of pd, but couldn't find the right part.

    Thank for help,
    Xaver

    @jancsika 2.1.2 works and lets me delete the knobs without crashing. (Tested on win10)

    (When I correct the path in knopf2.pd from [room_sim_2d ... ] to [iemgui/room_sim_2d ... ] it still doesn't show any knobs. I don't know, if it's because of my code or if there is another error with iemgui. I don't care as I changed the knobs to mknobs anyway, which is an easier and cleaner solution)

    I discovered another error while trying 2.1.2.:
    Unlike pd, Purr Data opens .pd files in the same instance of Purr Data ( is that intendet?). Opening a .pd file by double click doesn't work, when an instance of Purr Data is running and the path to the .pd file contains a german Umlaut ( ü ). Output in console is: error: <filename> : read failed

    The last version of pyext is from 2012, but it is stable and works fine with vanilla 0.47-1.

    [pd~] doesn't work on both of my windows machines, win7 and win10. I use the Purr Data version for win 64 you linked on the top of this thread
