    Hi,
    As far as I can tell, jit.change's "report" mode is backwards.
    Expected: a different matrix into jit.change should trigger a report 1, the same matrix should trigger a "report 0" message. (As per HTML reference)
    Results: The real results are the reverse - "report 0" for a changed matrix, "report 1" for a different one.

      The logic here is that of == - are the two matrices equal? 0 = false; 1 = true -- so as far as that goes, the object works properly.

      Yes, what you wrote is correct, and this is the behaviour of jit.change. But, what I read in the HTML reference is the reverse:
      "With report set to on (1), jit.change will behave a bit like Max's == object. If jit.change determines that the matrix input has not changed (within the parameters set with the mode and thresh attributes), it will send the message report 0 from its rightmost outlet. If the matrix input has changed, jit.change will send the message report 1."
      this says that: [same matrix in] -- [jit.change] = 0 [different matrix in] -- [jit.change] = 1
      which is the opposite of ==.
      Right?
      Cheers Evan

      Yeah. That's a documentation bug - will be fixed for Max 5. Thanks!

      You're welcome - it was such huge doc bug that after 5 years (?) of jitter being around, no one else has realized it... :)
      cheers evan
