Re: Question on Active Sensing message.

    The world is small.

    How interesting!

    
    Let me explain, what I wish to accomplish.

    All my previous keyboards and MIDI equipment use Active Sensing.

    Keystation does not.

    It does not even use running protocol.

    In example, when I play a C-major chord, I would normally expect a
    keyboard to send this: 144 60 100 64 100 67 100

    Keystation sends this instead: 144 60 100 144 64 100 144 67 100

    (of course assuming the velocity was 100)

    
    So, the bottom line is: Keystation "speaks strange".

    The manual does not even include MIDI Implementation Chart, so there
    is no document to consult with.

    
    I like Keystation very very much.

    It just "speaks strange".

    Otherwise it is great and feels good.

    
    I was just wondering if there is anyone else, who has Keystation and
    can observe the same MIDI communication (because there are no
    documents to double-check).

    
    Thank you, guys, for all your comments and help.

    
    Kind regards,

    
    Robert

          Robert - we went over this on IRC.

            
          Contrary to you apparent pre-existing belief, *most* MIDI
          equipment does NOT send active sense messages. I don't know
          what you're trying to accomplish (you said you planned to
          write your own software), but if it is based around the idea
          that MIDI gear sends active sense messages when connected, it
          isn't going to work in the general case.

             Dear All,

              
              Does anybody use M-Audio Keystation 88?

              Does it transmit MIDI "Active Sensing" message?

              I have one and it does not seem to transmit "Active
              Sensing" at all.

              Do you think it is a design feature, or a technical fault
              of the unit?

              
              Kind regards,
