I did some research (though I had never tried to make any sort of Max patch before) and was able to find a way to properly get the devices and parameters. You can see an example in this "official sample" .amxd http://www.mediafire.com/download/sqxmmvuqpr6zwin/Signal_to_Live_Param.amxd

Given this, you'll be able to select a device (I am using Live 9, also). After spending time looking at the patch, it seems that basically all you'd need to do to get this working properly (aside from using the method in the above to find the proper device id for live.remote~) is to get the min and max value of the selected parameter, and set the scale to these values.

Perhaps somebody with better Max skills can do this. I don't expect it to take too long after this - I just could not figure out at all how to properly get the min and max values for a parameter, though I would have expected this to be an easy API call.
