    Hi All,

    Pd keeps hanging and then crashing, or sometimes just hanging and I have to force quit. This usually happens right after I switch dsp processing off and then back on, but it's not really constant.

    I'm using PD-Extended 0.43.4
    It also says Tcl version 8.5.11 - I don't know what it means.

    I'm running PD on a 2011 macbook pro 15" intel i7 4GB ram OSX 10.6.8

    So far I've been using only the internal sound device, but I'm planning on using PD with Avid MBox 3 Pro.

    If you need any more info just let me know, but please help!

    Hi all,

    I built a patch that uses phasor to read from a table - quite simple really.
    Everything works fine when I "bang" it myself - all notes sound the same, phasor syncs to my bang. If I connect a [key] to the bang I play the patch from my keyboard and it's working: all notes sound the same, phasor syncs no matter how fast I bang it.

    BUT - when connected to a [metro], each note sounds different: it seems like phasor is syncing a bit differently each time!

    Got into it a little bit, and here's what I found:

    There is a correlation between the frequency of the [metro] and the number of different sounds I'm getting. 500ms produces two alternating sounds. 450ms produces a series of 13(?) different sounds that loop over and over in a cycles. In fact, each [metro] value produces its own repetitive series of sounds.


    I managed to find a [metro] value that seems to produce a stable sound: 476.01 ms.
    Then I found out that half that value and twice that value work as well.
    Changing the sample rate to 48KHz creates a dramatic change: every [metro] value that is a multiple of 4 would stabilize the sound.
    And at sample rate of 24Khz, only [metro] values that are multiples of 8 produced a steady syncing of [phasor].

    OK... So can someone tell me what's going on?

    And... is there a better way to achieve a reliable synced reading of waveforms in PD?

    Hey, any news on this issue?

    I'm having a similar problem with seemingly-not-random-yet-hard-to-recreate crashes. when changing from jack to audioport.

    also a similar setup: a 2011 macbook pro, 15-inch, os 10.6.8, pd 0.43.3-extended

    Hi Sebfumaster, thanks for your reply!

    Your analysis was correct, so I downloaded mmb's [vphsor~] and replaced it in the patch - and it worked!

    Thanks so much,
