OK, let's take an example from your composition, the "width" input
splitter you've got on the left side of the composition. Let's say you
want to control that with the top left knob on the Carillon.
First you'll need to use one of the MIDI input patches. There's a
built-in one in Quartz called "MIDI Controllers Receiver". There's
also the Kineme plugin that was mentioned in a previous reply, but
I'll just explain for now with the built-in one.
Drag that patch out to the left of your width input, and leave some
space. You're going to need a math patch between the MIDI input and
the width. For the MIDI patch, select it and use the patch inspector
to get to "Settings". For source you can leave the "All" check box on,
unless you have multiple controllers and need to be more precise. For
channels, if you know the MIDI channel your Carillon transmits on, you
can turn off the other channels, otherwise, leave them all on. As for
the controller #, you have two options: try to have the patch auto-
learn (similar to music software like Reason, etc.) - hit the "Learn
Controller to Observe" button and twist the desired knob on your
controller. Or if you know the controller number that knob sends out,
you can choose it manually from the popup list.
Now, MIDI controllers send out a value between 0-127. The width patch
takes a number between .5 and 10. So you need the math patch to modify
the 0-127 to .5-10. So you want to put some division on the math to
make sure that 127 translates to 10, and 0 = .5. So try dividing by
12.7. And a second operation on the math patch adds .5. It will
probably need a bit of tweaking beyond that, but that's basically how
I do it.
Once you've got the right settings connect the MIDI to the math, and
the math to the width input.

got a very good deal on it.. and it works with reactor++
fantastic !!! but i've followed your instructions and I cant get any
signal from the controllers to alter my patch..] re the connecting
to midi tread....

Just imagine you are speaking to a small child and walk me though
this (gig in a few day time doing the visuals and I dont want to
appear a total fool)..
here the patch Im trying to control... its good fun anyway so feel
free to have a play
BTW you will need the GL patches from
http://kineme.net/QuartzComposerPatches/GLTools
for this to work....
please Help you kind people... Thanks MArk
