sfplay~ "pos" message for scrubbing disk audio files

    Jun 01 2009 | 12:10 pm
    Buried in the umenu help file, in [p autopopulate], is an example with sfplay~ and a playback bar. It sends "pos 0. to 1." to sfplay~ and this sets the playback position over the entire piece. It can be useful for scrubbing or jumping around instead of using seek and msec points, or using play~ etc, if you want to read from disk instead of a buffer~. Also interesting is that sending "pos" messages will update the playback bar even if it's not directly connected to the sfplay~, which seemed strange. The message wasn't documented anywhere I could find.
    The playback bar claims to only control movies, so is this wrong, or does sfplay~ handle files as a sort of movie? Either way, it wasn't obvious that it could be used for this. Not that I'm complaining, it's already been handy...

      That's great, but it doesn't work with cues!
      With cues, in max window we can read:
      sfplay~ -- seek: no open file
      But this could be a great feature to sfplay!

      cues work fine here, you can still do the "pos" message for scrubbing or jumping around. XP, 5.0.7

      Hi again
      I'm trying to use an message [pos $1] with in an patch I'm building.
      Please, see if work on your computer.
      Open zip copy folder to your disk (all files) open TSC_a.maxpat drop some files into Audio Files hit play button on any player
      try to scrub -> Max windows sfplay seek: no open file
      The players.maxpat is the one with the scrubing bar!
      BTW, I'm using Max 5.0.7 Thanks!

      Nice one. I modded it to make the play button work. Unfortunately, it looses track of the position on the playbar when you hit pause. Also, it relies on the state of a toggle, which is lame.

      How about this? Works the same as the quicktime playbar but you can add your own bits as well, much more fun.
