Hello,
You can in example try to do this:
1. Select Turing for a Random modulator.
2. Set it's Flip to 100%.
3. Set it's Length to 1.
4. Set it's Rate to whatever give you the longest Loop/ the lowest rate.
5. Select the prefered KBD Reset Source. In example Poly KBD.
This will make the current stage flip on Note On. It will work as long as you don't need the change to stay longer than the Rate you have set. It would have been nice to have a none loop option.
Using this as a modulator for one parameter using Negative modulation and for another using Positive modulation should make them work opposite each other. That could be modulating 2 engines Output volume.
