  I think Max should be awarded the "Ask the Impossible Prize 2008" :-).

  I bet even the CS80´s designers didn´t think about this... it was just a design which developed its own unexpected idiosyncracies :-).

  But I'm not getting how it works in a technical way: I mean, the NANDs before the sample and hold module should output all the gates at the same time because of the "0" sent to the NANDs by the Sustain II switch, and the SH circuit should hold the gate forever...how it happens that notes release ?

  Yes, Stephen, it does so but it's more deep: I call this effect the
  "clockwise swirl in Australia", that is reverses a "steal the oldest"
  into "steal the latest" note, if I understand it correctly, taking in
  all the dying notes as a whole "last note"....or am I wrong, am I?

  If I remember correctly, Sustain 2 is the mode where you can use the
  pitch ribbon to bend the note even when you´re keeping it sustained
  using the footpedal. Sustain 1 doesn´t do this.As soon as you lift
  your hands from the keyboard, the ribbon won´t be controlling the
  notes anymore.

  Hm, I ought to be playing my CS80 more often, I guess...

  Hi all
  I ask your kind help in explaining the difference between "Sustain" I
  and II.
  A first question: what is the method of stealing the notes with CS80
  in Sustain I, I mean, how the notes are stealed when all voices are
  assigned when Sustain I is applied? Is it "steal the oldest note"?
  And what about the Sustain II? Does the method change to "steal the
  last played note"?
  Question is: if the KAS assigns to newest note all the time, why the
  envelopes do retrigger in "Sustain I" ?
  Please, Kent or Chris or anybody skilled, the patents or documents on
  JH's site don't help me, can you give me a simple explaination?
  Thanks for your care.
  Max
