Heyho everyone,
i thought that some of you might be interested in that little script i wrote for handling a rotary effect.
I also attached a rackspace which is using the B3-V organ VST from Arturia, so if you own this plugin too, you might be ‘ready to go’ with this one. But i think it should be easy to adapt to other similar plugins.
Besides the normal button widgets (LED-buttons on the right), there is the Leslie-section (with the big status label). As you can see, there is one toggle switch for the rotary speed and another one for the brake.
Luckily there are enough buttons on my keyboard (M-Audio Code 61) to map all those widgets to, so i also mapped the leslie switches to hardware buttons (see widget captions ‘B1’ and ‘B2’).
This allows me to switch the Leslie with the buttons - no magic so far. 
But what does the script?
The script allows you to switch the leslie speed also by shortly pressing the aftertouch (need a value >80 to prevent you from accidentally switching the speed), OR you can use a sustain pedal to do the switching (because the sustain is passed through, you may also do a ‘keyboard-slide’ while the leslie accelerates, which can be a cool effect). In addition to this, the big widget will change its text according to the chosen speed, so it always gives you a clear information (FAST/SLOW/STOP).
That’s it - maybe you like it?
