Data Array anyone?



  • I'm curious if anyone has experience using the Data Array actor; I'm not entirely clear from the manual if it will do what I want done. Using columns of numbers generated by a Logomatic, I'd like to convert these into waveforms via some sort of synthesis. Is the rate that the Data Array actor reads a variable? The Logomatic capture data at about 400Hz per sensor, so this will clearly need to be scaled. Ultimately, I'd like to be able to convert these as streamed data over wifi or Bluetooth, but I'm not sure what kind of actor that would involve yet. Any thoughts?

    I haven't tested the speed of the dataarray actor. One thing to keep in mind is that it reads and writes to a text file.
    The actor reads and writes rows of data, this may impact your usage.
    Also it does take a little getting used to, but once you have its interface worked out it is a very powerful actor.



  • Thanks for the input.  That's not exactly what I need, which is a way to translate text files into data streams, like audio or video control.  Is there a different actor that does that?

    You can still output the data as a series of values.
    You recall a row of data and then move thru the row from value 1 to the last value.
    You can output them in sequence if that is what you are looking to do.
    I can't think of any other actor that will work similarly for you.
    Do you have control over the format of the text file created by your Logomatic?

    This might help a little...
