How to control channel volume with velocity in Absynth?

I am trying to create a nonlinear velocity response for a channel's volume. For velocities from 0-60 I want velocity mapped linearly, so that small velocity results in low volume, and for velocity of 60 to result in some channel volume that I choose (say 50%). Then for velocity above 60 I want the volume to start ramping down, so that high velocities progressively reduce the volume.

The reason I want to do this is create a cross fade of two channels based on velocity. So I would do same as above for a second channel but just invert. That way for low velocities, channel A is dominant with a bit of channel B. Then for velocities above 60, channel A starts fading out and channel B starts to dominate.

I simply can't figure out how to do this in absynth.

Any ideas for how to do this in a simpler manner?

thanks!

 

For the nonlinear response:
See screenshot attached for example.

1. In the Env Window, select the Osc Module, then the Channel Vol Parameter.
2. Select Control Driven envelope Mode from the drop down menu.
3. Choose via Velocity in the second drop down menu.
4. Draw a curve (left-most will be 0, and right most as 127 Velocity).
5. Right Click to choose a new breakpoint, take note of the (Selected breakpoint) values you want, I.e. 64 is halfway, but it's still measured along Absynth time / Breakpoint timeline. The second breakpoint will show you how far along from the previous, so if you'd like 60% of the Velocity/time you could choose 0.6 seconds, and the final breakpoint distance as 0.4 seconds.

Alternatively, switch to Absynth time to see a total 1.0 second for the final breakpoint.
6. Note that the pattern you draw is quantised into 127 values, so it doesn't matter on the absolute scale what the numbers are, whether it's 1 or 14 seconds long. A simple up/down ramp will convert easily.
