[sdiy] Real piano keyboards: any use?

[cheater cheater]

An AR is a non-symmetric LPF that you put a gate into and get an AR
envelope out of.[1]

An assymmetric LPF is an LPF where the 'slew rate'*is set separately
for rising and falling signals.

*(actually: time coefficients)

[1] That's why different gate designs make your synth sound
differently. It's all in the transient!
