Easiest way to fill matrixctrl with random values?

I'd use jit.noise and add a little scaling voodoo.
Your mileage may vary, what with being up north
and all. :-)

"It's grim up north", wasn't that the wisdom that we received from The Justified Ancients of Mu Mu? ;)

And grim they are - because I don't have Jitter!

Back to the drawing board, I guess.

Not in front of Max right now, so bear with me, but this should be pretty easy.

You'll need two [uzi] objects. One for the number of columns, and one for the number of rows. Say your maxtrix is 4x8 then you'll want an [uzi 4] and an [uzi 8]. The right outlet of those will dump out the numbers 0-3 and 0-7. Each time a number comes out of the first uzi, put it into the right inlet of a pack and bang the second uzi. The second uzi will go into the left inlet of pack.

This should output lists "0 0", "0 1", "0 2", ... "3 7"
Those are your matrix coordinates.

Then you just need to pick a random 0 or 1 for each coordinate (try [random]) and append it to the coordinate list and send it to matrixctrl.

Here is the method Adam described:

I like doing stuff like this with Jitter, because it's easily scalable.

Aye, I was figuring this out as well, to fill the [matrixctrl] with random values. For my FM Sequencer, which i happily ended up figuring out after 2 days of messing around.

After a few days of banging my head against the wall, messing with Max, did actually use the Jitter method instead, mainly because it was less cumbersome and i had paid for Jitter but have not used it to a great extent yet. So now have put my money to use :)

The other non-Jitter methods are more than fine, but if you do have Jitter, use the Jitter method that Andrew has pointed out. It is less space used and much easier...

the one thing i am now figuring out now, is how to randomize a [function] ?

If any of you know, let me know please

Cheers...

Here's an adaptation of the uzi approach. You may want to hardcode a start/end point, and maybe enforce a minimum number of points by running the first [random] through a [+].

Nice Adam, Cheers very much...
