VST fun and games

    hey folks well, specifically Tiger folks running Max5 however, interested to here if this is an issue beyond OSX 10.4.11
    right any time i load a vst~ object i get general intermittent audio drop-outs, maybe once or twice a minute at most
    this is only happening when i instantiate the vst~ object with a valid plugin name and only with regards to Max5
    all is well otherwise and all is well in Max4.6 it makes no difference when i swap machines it makes no difference when i turn off all wifi and routers it makes no difference when i select a pro soundcard it makes no difference what vst is loaded or whether it is opened or sounding
    this is doing my nut in, because I can't (along with c74 support) get to the bottom of it
    it just needs one other person to observe this audio drop out to stop me going crazy here
    if you run the patch attached it'll be a bit dull and may take a few minutes to conclude - but it'd be mighty appreciated, i can fwd results to support
    of note: it glitches on the audio output side, but if a quickrecord is also recording the tone it is *not* affecting the audio recorded, but which had sounded glitchy
    we are talking about 50-100ms drops, very easy to hear and *only* when vst~ is activated in Max5
    anyone got any clues ?? pleaze ??
    can you confirm this is a bug ??
    best s

      My first suggestion would be to check your signal vector size, but there's also the memory from long ago that there was a problem with airports around that time that played havoc with things. Try turning your airport off, if you have one.
      Also, the use of mute~ is generally deprecated. It's better to put things in a poly~ and turn 'em on and off from there these days.

      hey thanks for posting
      i'd already turned off airport and even downed the whole network to be safe
      the signal vector size is 64, but i'll experiment above
      mute~ is there for the purposes of that test patch only ! it just allows an A/B comparison between normal and malfunctioning without any user patching - [ not sure it'd make sense in a poly in this instance but it's a good tip for other cases ]
      this still doesn't explain why there is only one circumstance reliably causing fault even if all else is constant
      there are glitches for me using vst~ in max5 on tiger no other triggers for this fault except that !!
      it happens on both of my intel macs i've emptied the vst folder etc etc
      the fun and games continue

      I have had another Tiger user confirm the same behaviour - so that's three machines - it'd be very helpful if someone (anyone please) could give the patch a try ! FWIW increasing the sample vector size reduces the frequency of the glitches but does not resolve the issue.

      fyi, if you are experiencing this issue, please either wait for 5.0.8, or use the updated vst~ posted on a previous thread:
