I could really use some good explanation of matrixctrl. It isn't in the Max45ReferenceManual (although it is referred-to repeatedly). I am gradually figuring it out, but it sure would be nice to just have some documentation instead of a black box. I see in some threads you can send in arguments like getrow and getcol - again, no doc to be found. Am I looking in the wrong place (Documentation folder of my MaxMSP 4.6 install)?

Also, I saw somewhere something mentioned on some thread about an object called lrow that converts 8 binary values to a 0-255 bitmask value like what you send to an LED grid driver... I can't find anything about this either. Maybe I made it up.

wheres-the-matrixctrl-documentation

Oh, I found it by searching for the term in the pdf reference manual.

For anyone else who is looking for this, it begins on page 306 of Max45ReferenceManual.pdf, after "match".

It's just not in the index for some reason.

...or if you download the new version of the doc from cycling74 Documentation section it has been added to the index.

It's on page 306 of Max46ReferenceManual.pdf. Maybe you upgraded from 4.5 to 4.6, and didn't download the documentation?

If you come by the lrow object please let us know

check the object bitlist. it is in the jasch object package. If you send it a list of binary numbers it will output an int, give it an int and it will output a list of binary numbers.

Awesome! Exactly what I'm looking for. Thanks, will check it out.

There is some code that does the bitshift thing in the monome examples, but I thought I saw an object for it.

But this is actually for my monome-inspired controller project:

Awesome!  Exactly what I'm looking for.  Thanks, will check it out.

You should also check the bit and byte externals, part of Peter

If you need to shift the bits in the list check out the zl object. It has many different modes,one of which is rotate (rot) which will move the elements in a list either to the right or left depending on what is in the right inlet/argument.

BTW I have had multiple crashes with zl rot on XP / 4.6.2, it seems to happen when you change the "amount to rotate" before there's a list in the left inlet. Not totally sure if it's reproducible each time but I do remember it happening *often*. Also not sure if it's been fixed or if it's a problem on Mac. As long as you send the left inlet something (even a single-element list) first, things have been fine. It's too bad because it's a great feature! Just a precaution, wondering if this has been seen elsewhere. I was working a lot with manipulating multisliders and had the zl rot, which was great when it worked, but I remember literally being scared to click on it for fear of suddenly seeing my desktop and Max totally quit...

Not sure if this should be in its own thread, I imagine it may be fixed in 5, or maybe it's just my machine.

where's the matrixctrl documentation?
