Hello,

is it possible to have OSC listeners on different ports? Like

giOSC1 OSCinit $PORT1
giOSC2 OSCinit $PORT1+1
giOSC3 OSCinit $PORT1+2

and different instances of an intrument would use listeners on those ports like

instr getOSC
	index = p4-1
	if (index==0) then 
		ihandle = giOSC1
	elseif (index==1) then
		ihandle = giOSC2
	endif
	kCoordinates OSClisten ihandle, "/3/xy", "ff", kX,kY
	; etc
endin


looks like yes, but when I press "Stop" in Csoundqt, the program crashes.
Running it in  gdb gives message:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7fffccbf4700 (LWP 5521)]
0x00007fffdd3dd72b in ?? () from /usr/local/lib/csound/plugins64/libosc.so

I found an old e-mail thread inititated by John Ffitch about need to have 
severeal listeners http://csound.1045644.n5.nabble.com/Design-question-for-
cs5-OSC-td1094223.html
but I did not understand what the final decision was.

I need to have different listeners since I need to receive messages from 
different mobile devices that use TouchOSC. In TouchOSC I can configure the 
outgoing port but nothing much else so I don't know other ways how I could 
understand which device is sending the message.

thanks!

The code is supposed to allow multiple listeners, but  have never tried it.
Looks like I need to construct an example to see what is wrong.  First
code-read showed nothing

I have successfully used two OSCinit and  instances using different ports. Tested on Linux only. I did not however use macro or port number increments like in your example. 
I would suggest trying hard coded port numbers at first just to see that the port numbers are not the issue. 

What I have had issues with is receiving illegal values, such as negative amplitude values. It is in my understanding important to make sure received values are conditioned properly before actually using them inside csound. 

It seems you are using TouchOSC for sending messages? That is what I used when setting my listeners up, so I don't believe it should be problems in that end. 

Best regards,
/Anders

Hello,

thanks, I created a small test file (attached), indeed, it works fine. There 
must be something else wrong with my original csd. Try to figure it out.
