//load QC
NSString* path = [[NSBundle mainBundle] pathForResource:@”MyQCPatch” ofType:@”qtz”];

//We assume the “patch” parameter of the “QCView” QCView instance has been bound to the
//”patch” property of the QCPatchController in Interface Builder

if([qcView loadCompositionFromFile:path]) {

//The composition has been successfully replaced on the QCPatchController and its QCView
//and the bindings have been updated

} else {
NSLog(@”Could not load QC resource.”);
}

Ian

You can get values from 0 to 1 by dividing with 1000

If you want values from -1 to 1 subtract by 500 then divide by 500.

But everytime you change the QC composition you have to save it, reload it in Interface Builder and then rebuild the app in Xcode.

second note is about the values: the sensors give values from 0 to 999 right? and in quartz composer a lot of things happen between 0 and 1… so you’ll have to do some math operations in QC…

just my 2 c.
