poly~ and groove~ makes crash?


    May 19 2006 | 1:51 am
    Hi everyone,
    I've recently built a granulation patch (I know, so original!) using
    [groove~] and [poly~], that uses a Wacom tablet's X, Y, and pressure
    values to control playback position, rate/direction, and amplitude,
    respectively. My problem is that, after some use, and under
    unspecific conditions (at least, unspecific to my knowledge), the
    process hiccups and crashes, like so:

    I'm running about 50 instances of the grain patch. My guess is that,
    if it isn't a bug of [groove~], or just my computer getting bogged,
    I'm sending my messages to it too quickly or in the wrong order.
    Because I figure most people don't use or have a Wacom tablet, I've
    included a more-or-less identical patch driven by a mouse rather than
    a tablet. If you have a Wacom tablet, you'll need the [wacom] object
    available here (http://www.jmcouturier.com/download.html). Granted, I
    haven't been able to crash the mouse version, but I don't think that's
    the culprit. Is it possible that the [metro] that's stuffing the
    [pack] out of the [wacom]/[mousestate] could cause a crash? I added
    that recently so that audio would persist even when the Wacom tablet
    wasn't moving, but I also didn't experience any crashes until after I
    added it. But then again, I don't understand how it would cause it,
    either.
    All the files are attached.
    Thanks for your time,
    Evan

      It appears that the mailing list attachment didn't come through on the message board side. Here they are, in text form:
      POLY-GRAIN (mouse version):
      max v2;
      THE-GRAIN (the poly~ object):
      max v2;
      POLY-GRAIN-WACOM (Wacom tablet version):
