Within Equator, each dimension of touch (Strike, Press, Glide, Slide and Lift) has four alternate response curves which can be assigned independently to synthesizer parameters. This is a very powerful feature, allowing you to use the same gesture in multiple ways simultaneously. 

For example, you can assign a linear Press response to the filter's cutoff frequency, and at the same time a heavily downward-curved response to the LFO frequency. Now, as you increase the pressure on the keywaves, the filter will open steadily while the LFO frequency's response will increase significantly only in the higher pressure range.

Multiple Expression curves

Click on the icon in the top right of the Modulation Source’s panel to see all four response curves. Click to select one. It will display in full size and can now be assigned to any parameter. This assignment is entirely separate from the other response curves of the same Modulation Source.
