[chuck-users] odd Hid behavior maybe just on OS 10.7

Tue Sep 18 19:14:52 EDT 2012

Hi all, 

We are doing a piece in our laptop orch that uses Hid input from the keyboard and mouse. The group does not have matching machines. All but 1 are Macs, with the OS ranging from 10.6.x to 10.8.2. The code (pasted below) works on the windows machine and the 10.6 and 10.8 Macs, but not on any of the machines running OS 10.7.4.

Thoughts?

Thanks,
Jeff

// The keyboard controls the pitch of this instrument,
//    while the mouse controls both the loudness and the timbre.
// Clicking any button will turn the note on,
//    while unclicking that button will turn it off.
// The SPEED of the left-right motion controls how loud the note is
//    (the faster the motion, the louder it will be.)
// The up-down position of the mouse on the screen controls how
//    bright/complex the note's timbre will be.
//    (the higher up, the more brighter it will be.)
//
// (push key that wasn't mapped for a really cool sound, like '~')
