I am trying to make a selection object for 12 outputs where only two are active at a given time. I have noticed that [dac~] does not take set messages, so what are some ideas for dealing with this?
right now I am using 12 [dac~] and 12 corresponding [*~] with 1's or 0's in the right inlet...

to elaborate:
a sample is selected and then bangs a generator that selects two numbers between 1 and 12 thus enabling those two outputs for that sample, so....when the next sample comes around, and another set of numbers is randomly chosen (via xrandom so nothing repeats) which activate a new pair of outputs and disables the previous pair.
my problem is turning off the previous pair, so that only 2 outputs remain active at any given time.

thanks for any ideas or suggestions...

what about

[dac~ 0 1 2 3 4 5 6 7 8 9 10 11]

with 12 [*~]? maybe some catch~ and throw~?

i think [dac~] starts counting from 1, not 0

so it would be [dac~ 1 2 3 4 5 6 7 8 9 10 11 12].

you can have more than one [dac~] object, but it's very unusual to use them, in my experience - normally you want to have some kind of mixer for all your sounds and a master volume level controller

something like this might work for the logic, with as many copies as channels?

"list 3 5" or whatever goes in here:
|
[unpack f f]
| |
[== $1] [== $1] // replace $1 with the channel number
| /
[|| ]
|
"float 1" or "float 0" comes out here!

what it does is check if any of the inputs are for this channel (|| is logical "or").

if you want to avoid repeated 1s or 0s in a row, you can use [change]

thanks, I see that this works as you describe, but I am not sure it is doing what I need it to do... or if I do have it set up correctly...or if I have not explained what I am trying to do well.

I am not very familiar with list, so I may be doing something wrong...but should list have two variables $1 $2 that will receive the random numbers?
and should the [== $1] hold the channel number or hold a variable and receive a different number each time?

thanks

okay, I made something that works for my needs, probably could be improved in a big way by the more expert users on this forum. patch is attached. I am sure this is over done, but it works, if anybody cares to refine it I would be thankful...

this is for a specific piece I am working on that uses 12 speakers, but only two at a time for a particular sample. On load it bangs two channels on, then when the inlet is banged it turns those two off, and turns on two different channels, and so on and so on. It's sort of messy, but I think it makes sense if you bang through it you can see the channels switch. Maybe someone else is using a 12 channel system?:)

Think that it would be a good idea, or possible, to make Pd's [dac~] work like [dac~] in Max, where it can accept set messages for output channel?

ah, i think the catch~ throw~ things might work for "set messages to dac~":

have 12x catch~ for the physical channels, and 2x throw~ for the samples, and send "set" messages to the throws - makefilename %d can help convert floats into names of the buses to put into the set messages

hi everybody. my system windows 7.Pd Version: 0.43.4-extended
Tcl Version: 8.5.13. i trying use "xrandom" but impossible .because pd send message
"... couldn't create" ... and i am using "Edit" toolbar and " preferences " and working but for next time not working i should Repeat the "Edit" toolbar and " preferences "... how can create a object for ever?

It'd probably be best to make your own thread for this.. However, my windows 7 system also does this. You mean where you add a path in the startup area of pd and then next time you run it, its no longer in the preferences? What I have done to solve that is use a directory that is different than the install directory. One that works well for me is My Documents' directory. After adding a path there, it always opens/loads in pd.

I wonder would [demultiplex~] work for you.
