Saving Matrix Setups - possible bug (MAX's or mine)


    Apr 24 2006 | 4:52 pm
    Hi All,
    I'm building a patch that uses the Matrixctrl object to as a step sequencer, but I've found a problem that, and I'm wondering if someone has a solution or workaround.
    Using autopattr and pattrstorage, I've found that there is a limit to how big a matrix can be and still store data. Smaller matrixctrl's accurately commuincate with autopattr and pattr storage, but larger ones do not.
    Any ideas how I can save matrix states in large matrices? To complicate things, the matix appears IN a bpatcher IN another bpatcher - so, it's 2 levels below sea level, if that makes sense. :)
    Any thoughts?

      How large are talking about? I've done 10x64 without a problem.

      Any size which x3 >= 4094 exceeds the current limit of getbytes, which is used to allocate memory for pattr. Hopefully, a future version of Max or pattr will address this. For the moment, you can't do anything about it without breaking the matrixctrl into separate, smaller objects.

      Thanks for replying...
      I've found that 48 X 28 works, but 49 X 28 doesn't.
      48 X 28 gives a string of data in the 'Client Window' in pattrstorage, while 49 X 28 shows nothing in pattrstorage. BUT 49 X 27 does.
      Thoughts?
      Cheers -j

      Ahhhh... that explains it.
      Any thoughs on a clever workaround that won't require me breaking the matrix up?
      Thanks for your replies guys, Joel

      I had a stupid thought the other day about saving matrices. You might try using a base 62 system and store your binary rows in apha- numeric symbols. you can get 29 cells worth from 5 characters. get row would give binary numbers.

      The problem with "getrow" is the lack of a "setrow" message. Sure you can parse it (which I've done), but it would be so much simpler with the proposed partner message.

      i have managed to save large matrix (127*96) info using the good old preset object. it was also buried in a bpatcher. i was using it for sequencing as well

      I've managed to do it using the preset object BUT...
      My matrix is in a bpatcher, IN another bpatcher, so, I'm not sure if there is a solid way to to presets like that? Do you think?

      You can probably rig something up using jitter. May be more clinky than using preset though. Just a thought...

      i don't know if you've tried this but, look at the bpatcher inspectors and 'embed patch in parent'. that did the trick for me in any case
