matrixctrl / radiogroup feature request / routing advises

Hi list,

I have 2 problems

First one:
4 quicktime players, 8 outputs (on 3 projectors) with a matrixctrl doing the routing in between.
I want the players and the outputs to be turned off whenever they are not needed.
It would be easy if the matrixctrl would tell the number of the row/column being outputted after a getcolumn/row command.

Second one:
To make the interface more friendly I want to use radiogroup and text instead of directly the matrixctrl.
But like in the matrixctrl, I would like something like "one cell per row"
But I can find a way to change the state of toggles individually without changing the others, the flagmode doesn’t allow that.

Any ideas ???
Am I missing something obvious ?

Thanks

Here is a patch to illustrate:

btw, it’s a max6 patch, why does it says max 5 ?

The equivalent of "one non-zero cell per column" using [radiogroup] is to set the item type to "radio buttons" instead of "check boxes".

+1 for the matrixctrl to output the row/column number, but an easy workaround is by "set $1" to [prepend], then run the list through it, and [route] when you need it. Or open a corresponding [gate] outlet.

I think the [matrixctrl] might work more cleanly without sending the row or column number, but it might be a nice flag to set in the Inspector. With such a flag, when off (default for compatibility), it outputs:
0 0 1 1 0 0
On:
row 3 0 0 1 1 0 0
or
col 5 0 0 1 1 0 0

then you can just [zl slice] as needed.

Thanks for the replies,

@Luke,
For the radiogroup, I need "one cell per row"
But as they are separated objects, there are no rows…
@seejay,
I don’t really understand what you mean. That would be for check/uncheck some cells, right ?
I still want to use the graphic interface of the matrix, but I want to know when a row or column is empty. And I would like to that without a metronome.

So far I found something for the radiogroup thing and the metro/trig/gate is enough for what I need now.
Still, it could be so much easier…

ps:Why would matrixctrl be "dirtier" if outputting the row/col number ?

Only "dirtier" in that it has extra information which you already have, that is, when you send it the message to output a specific row/column. As it is now it’s just lists of raw data.

To check if a row/column (any list) contains only 0′s, there’s many ways, but [zl sum] –> sel 0 works. [zl filter 1] is a nice way to get any active cells and their indices. [listfunnel] might also be useful somewhere, somehow…
