MIDI Kinetics Forum

Within one of my first project builds I'd like to assign two faders to react as a zoom control for my edit window in Pro Tools.
This command is accessed as a key command in PT and moves one degree with each execution of the command on a qwerty keyboard.
How would I program these two faders to send this command in a repetitive fashion to allow a seamless zoom in/out & up/down?
I'm using OSC with the Lemur app and programing within the app itself.
Thanks.

Anything typed in a script which is set to "execute"
inside an object (fader in our case) will be executed each time the fader is moved.

If then we set it to execute it will be executed only when the x is rising - fader moving up.
If set it to execute it will be executed when the x is falling - fader moving down.

Then supposedly we use the keyout(target,key,state) function or the keycomboout(target,ctrl,alt,shift,key) function (Lemur Manual page 131) to output a keyboard press. So in , essense you need two scripts inside fader - one one expression x,+ and one on expression x,-.

But then the problem is, x inside lemur has greater resolution than just a range of 0 - 127 (midi) so you 'll end up with a super fast, not usable zooming function - so I guess you could create a custom expression to slow it down ( example, step=floor(x*100) ). But again, what happens if you open up a project which is completely zoomed out but you have left you fader at the "completely zoomed in" position? In that sense, I think its wiser to use two buttons - one to zoom in, one to zoom out.
