this isn't a mock. it's funny and stupid but not a mock. say you have milestone but you don't have a breath controller pedal. you can connect it to a knob but it's too hard to control expression, pitch and hit the keys at the same time.
here's what you do:
open an instance of the fruity formula controller and use the preset MOUSE POSITION. it will say MouseY. (meaning the mouse's up and down movements will control whatever you connect it to)
connect the breath control to the formula controller.
put your mouse on the floor (assuming you have a conventional mouse, or an optical one)
with double sided tape stick the bottom of your shoe to the mouse and move it up and down while playing. :p
i did it without the tape (used a bit of pressure and it worked)
surely not the best way to deal with things but it works.
of course, others can adapt this genius system
if they have or find a plug that uses automation via mouse movement.
