Thanks for your response, I'm slightly confused as I'm new to both phidgets and Max/msp, but really eager to get it to work...
It seems that there isn't a .mxo file for the stepper control within the os x- max/msp download package, only the 'PhidgetStepper.help' file. It's the only phidget module thats missing this file.
Surely this .mxo file is the external patcher object, and is essential....
Is it possible to obtain this file?
Thanks so very much
