[Csnd] (Touch)OSC and Csound

The Csound Mailinglist
1

Hello everybody!

I have some problems with setting up the connection from my iPad to my Mac for controlling Csound via TouchOSC.
I’m new to working with OSC, but i checked out the floss examples.

I initialised the connection via OSCinit in Csound and also tried out sending messages and printing them with the hexler protokol app, which works fine.
But i can’t get values inside my Csound patch, where i want wo print them.

Is there someone who has experience with this and can describe what i have to do to set everything up?
And does someone know if i can print OSC messages inside the terminal of MacOS for debugging purposes?

This is my test instrument and i don’t get errors.

Should you not check the value of kAmpT and kFreqT to see if thwere is a value avalilable for kAmp and kFreq?

I use OSC quite a lot but only between csoud instances so ? have nothing to say about the iPad, floss or touchOSC

Are the left arguments not like „trigger“ that just allow for checking if something changed there?
I thought the new values are written to the last argument of OSClisten and i can just use them i my instrument and ignore the ’trigger’ arguments.

Not my understanding The kAMmpT is zrero ifno messahge has been receied and 1 if it has. Otherwise what value could kAmp have?
   The manual looksclear to me

kans is set to 1 if a new message was received, or 0 if not. If multiple messages are received in a si.....

This is what i meant with „trigger“.

i thought kAmp is having then the values im sending on the adress i put in before „/fader1“ or whatever i put there.

Or does OSC behave differently? I’m a little bit stucked.

No one has experience with touchOsc and Csound?

I wrote a 2014 article on TouchOSC and Csound. It can be found, along with a lot of templates, as the last entry​ at: http://arthunkins.com/Android_Csound_Apps.htm .

I doubt, however, that it will have anything to do with your project. But nevertheless . . .

Hi!

I have used TouchOSC in serveral occasions in the past, it works like any other OSC sender.

Try this code:

giOSC OSCinit 9000

instr 1

kAmp init 0

kFreq init 0

kAmpData init 0

kFreqData init 0

kAmpT OSClisten giOSC,“/1/fader1”,“f”,kAmpData

kFreqT OSClisten giOSC,“/1/fader2”,“f”,kFreqData

if (kAmpT==1) then

kAmp = kAmpData

endif

if (kFreqT==1) then

kFreq = kFreqData

endif

printk2 kAmp

printk2 kFreq

; kAmp scale kAmp,0,-90,1.,0.

; printks2 “Amp: %d\n”,kAmp

; kFreq scale kFreq,80,320

; printks2 “Freq: %d\n”,kFreq

; aSig poscil3 ampdbfs(kAmp),kFreq

;

; outs aSig,aSig

endin

The idea is that you don’t use the data read bu OSClisten directly but put it to your “working” variable only when there is data.

I needed to change the OSC path according to my very old app, change it back what is correct for you.

Hope it helps!
