You will need Max For Live and the Mapulator Max Device.
Ok, you might be like, WTF is a center detent knob??? The most common example of this on DJ mixers. It is a knob that is a hi-pass when you turn it to the right and low-pass when you turn it to the left. Sweet huh?
So lets get started.
Load up Mapulator and 2 auto filters, one a high pass and one a low pass.
Highlight them all using SHIFT+click then group 'em using CTRL+G.
Macro the "Smart" knob on macro 1 or your MIDI controller knob or whatever.
Click the frequency on one of the auto filter then click "Learn" on mapulator. Do this for both. Make sure you choose 2 different parameters in the parameter drop menu.
Now move your macro and watch the line move back and forth, pretty huh?
Click to add modulation. Create a line that starts low and gets high just slightly before the middle for the LP and a line that is all the way down and starts rising just after the middle, I wouldn't have them exactly in the middle if your using a controller, just so you have some leeway.
And BAM! There you go:) Enjoy.
