Auto frequency cutoff modulation in software Korg or Moog

[augmented5th]

Hi How do I have modulating frequency cutoff (LPF cutoff) when I sound the notes, and have the rate of the modulation vary with aftertouch pressure?

I'd like to do with with any of
Korg MS-20
Korg Polysix
Arturia Moog Modular V

Thanks
