weird VIDDLL sound behaviour /bug?

    Hi dear Maxers! I am preparing some lectures, I wanted to show to my students how to trigger videos and I noticed a weird behaviour while using the VIDDLL engine: I had 3 videos loaded in 3 movies and I randomly triggered them via (frame 0,start) message, after I while I noticed a weird volume balance and I recognised that some videos went up with their volume. After some testing I heard sometimes some double triggering of the audio content and I had the feeling the jit.movie was randomly stacking up / loading more the one audio track per video (but this is just a feeling) I also recognised that if loading the same video in the same moment in 3 jit.movies the sound problem happens (at least on my computer -16inch MacBook latest macOS [10.15.2], latest MAX [8.1.3]) patch:

      sounds to me like it's simply the audio tracks adding together which makes it sound louder. if you want more control over the audio, use jit.movie~

      thanks for the answer Rob, Yes surely they are sounding louder when played all together after load, but I am not referring to that. If you turn ON the metro on top of the patch the movies play one at the time, there I can clearly hear that the first movie sounds normal, the second louder and the third way louder.

      I am routing back the output of my computer and checking the amplitude of each single video, as u can see the second and the third are getting louder

      I started using the jit.movie~ as I need to interactively and continuously change the rate of the video and it seems jit.movie~ behaves the best in this situation. I noticed an other curious behaviour thou, maybe this is related to the previous problem and can help? check out the attached video

      thanks for the video but the best way to get this addressed is to send along the patch and movie file you used. can send to me privately if preferred.
