How would you do a fade in / fade out rack ?

[chapelier fou]

This looks super simple, I want to make a rack where a Macro would make a fade in for the first portion (from -inf to 0dB) then stay at 0dB for the 2nd portion, then fade out to -inf for the last portion.

Using a single chain with fade in and fade out on the blue zone range doesn't work, because maximum attenuation is around -26.2 dB.

Ideas ??

No need for a rack. Use Shaper max device in Manual mode, draw the basic fade in/out, map it to any volume (in remote mode), and use its Manual knob to control 0-127

Nice use case for shaper, thanks for the advice !
(meanwhile I made my own trapezoid gain scanner in M4L).
