OSC messages, processing, and reacTIVision

donttouch · Post by **donttouch** » Tue Nov 20, 2007 4:15 am

does anyone know how to map osc / tuio messages to 2 apps? i want to have one instance of reactivision controling both ableton live and reactivision.

i'm runing live through max/msp, so it's all osc. (i'm not running reactivision in midi mode, although i can.)

also, does anyone know how to program one marker to control 3 / 4 different things in live? live only does midi learn, so if i have marker 0 put out x/y/rotation/note data as midi, it will only learn one of them. i cant figure how to map them to different controls. any ideas? is there a way to just type in the cc number?

from a pdf on the reactivision site, i found that they use a "connection manager" that takes tuio in and puts out connection info to the synth and visual engine. i assume this deals with the whole proximity thing where objects link together, but i also think that it splits the osc signal 2 ways.

see, i just need to have both max/msp and processing listen to the same osc signal from reactivision. that's all!!!

here's where i am so far:

Never done it but im guessing you could

Sorry, This i dont understand. But Live doesnt do OSC, so it seems you would have to convert the OSC messages to MIDI messages in Max/MSP

the way i do this with in max is to set up a message box "64 127 1" -> [noteout] obj. you might want to toss a [makenote] obj in there. Just go MIDI map mode in Live select yer control you want to map and click the message box in Max.

never sent OSC messags to mre than one prog, but wouldnt you just have to specify the proper port in MAX and Processing?
max you could use udpsend/receive
Processing dont know, never did OSC in Processing

Looks cool!!!

I replaced Max with Reactor, and the whole OSC vs MIDI reactivision thing got easy.

re, mapping: In Live you can map your stuff first with any other controller. Later assign the corresponding midi-messages to the fiducials/TUIO-messages in Max.

hey, THANKS guys! it's nice to see people helping these days...

so, 1) to clarify, live is of course runing midi. (generated by max msp.)

2) i'm really new to max and processing, could you perhaps post an example of what you are talking about with the max patch? (so i can open it and try it.) i also have (and am better at ) reaktor. so, if that would be better to make a patch with, it's there. BUT live is the goal program. i want to have live do all the audio playback / processing.

3) i have everything working, just not at the same time. ether:
i open live / max / reactivision
or
i open reactivision and processing.
i cant get them all to run at the same time! whenever i open max after processing, max seems to take over all the osc signal from processing. pretty much, whenever max is open, processing gets no osc. whats with that??? do programs that use osc have to link to eachother? or is the osc broadcasted over the entire port for anything to listen?
there's no problem with everything working on its own, just not all together...

i think the problem is more about udp ports. how do you tell 3333 to broadcast or multicast instead of a direct connection?

I actually don't know how to solve your problem, but maybe you find an answer at the reactivison forum on sourceforge

OSC is a machine wide transmit / receive - because it's IP based.

just copy that to MAX, then set the note you need, then click the button, it will send out that note to Live.

With the UDP thing. Ive never sent OSC to more than one App at a time. But my thought is that you can kind of daisy chain apps using diff port numbers. For instance. have reacTV send to MAX on port 8888, then have max echo to processing on Port 8889 . So youd have something like:

-reacTV udpsend 8888- ---> -MAX udpreceive 8888- then -MAX udpsend 8889- ---> -Processing udpreceive 8889-

There might be a more elegant solution than that but that seems like it would work. Your prob better off asking over at the cycling boards or maybe checking the processing board too. The Max board seems a bit quicker with responding than the processing stuff.
Good Luck!

hmmm, well that midi utility is real cool! (saves me some time maping with external controlers...)

but how would i tell these programs to send out again on different ports? i've only started useing max and processing like 4 days ago. but i get things fast.. do you know of a way to copy and paste the data like i did with that midi utility? (i learn best by dissection.) then perhaps i could impliment it into my patches for use with reactivision.

i think that you have to know how to make xml files that specify how the whole udp ports will work, then reference them from within processing.

and.. i AM posting all this to the reactivision / max / puredata forums, as well as youtube. just so few people seem to know about this stuff!

thanks so much for helping!

heres a couple max patches demonstrating the technique i mentioned above. Like I said theres gotta be a nicer way to do it- but this should work.

Pseudo ReacTV

Psuedo Max

#P newex 23 156 115 196617 udpsend localhost 8001;
#P newex 23 80 86 196617 udpreceive 8000;
#P comment 23 177 115 196617 from max to processing;
#P comment 25 21 63 196617 pseudo max;
#P user panel 13 60 190 140;
#X brgb 191 174 206;
#X frgb 0 0 0;
#X border 1;
#X rounded 0;
#X shadow 0;
#X done;
#P background;
#P connect 3 0 4 0;
#P connect 3 0 7 0;
#P connect 7 0 8 0;
#P pop;

So open up psuedo ReacTV and then open up PseudoMax. Play with the numberbox in PseudoReacTV and it will send and Osc type message to PseudoMax on port 8000. Pseudomax will then forward the message to port 8001, have Processing listening on this port. Definately look into the max documentation and help files...
