Nick, What is your sensor ? what is your problem? I have many things on different sensors but I do you want to do, So many ressources online like Gdif, Dot or Jamoma can help you to achieve your project. For me it's necessary to understand what do you want to do?

hey mortimer, I simply want to be able to get accelerometer data (streaming numbers) our of the c74 app on iphone to be able to trigger midi events - I can find no resources or way to do it in the example patch though. Any help you might offer would be great.

Nick

hi nick, i dont know about c74 iphone app+max object cos is mac only, but if the c74 app dont send the iphone accl data you can use touchosc or msa remote iphone apps and udpreceive and osc cnmat max objects. best!

Thanks Carsol, I'm having such weird problems. I'm trying now to use TouchOSC and their example patches and I seem to be able to send bangs from my computer to iphone but not the other way around after I connect them... I have no idea what to do....

hi nick, here you have what i use to communicate both ways with iphone touchosc you need OpenSoundControl external from CNMAT and change ips/ports and osc variable names to match your setting...

hope this helps..

Regarding your OP, here's the c74 patch, just connect to the same wifi network as your iPhone/iPad (or go through a local network), load the c74 app on your phone, and launch this patch.

It's actually quite simple.

Thanks for this guys, helpful stuff!

Now, a question on how to make these data usable.

Even with the iPhone sitting still on the table, values are still being put out continuously (with changes happening in the hundredths and smaller digits.) Also, what's determining the reference point for "negative" space - is it the iPhone's orientation when first connected? x and y will often be consistently negative at rest.

Anyone have any experience in application of the accelerometer?
