Yamaha CS80

same as on an 80 max......hand held notes are not stolen......
there is no hold pedal....therefore sustain/releasing notes are stolen as they aren't held...

Wow
I'm getting different feedbacks, now I'm reading a complete different answer from Scott (lost somewhere by Yahoo, thank you!): I mean, once I remember I *did* read that the CS assigner ignores any more voice pressed; so,doesn't it  steal a voice when all are actually playing?? That could make sense as the voice block S/R could accept a number of inputs/avaliable voices; anybody would confirm this?

  Sorry if some attributions got messed up in my in-line notes below.

  Anyway, it seems like a few people have worked on replacement KAS
  boards for the CS80. However, it doesn't appear than anyone has gotten
  one to the point of mass production / sales. I'm wondering if those
  of you working on them would like to get together to share ideas and
  maybe get a joint design working and ready to sell to the CS80
  populous. I know there are issues of intellectual property and getting
  paid for design work, but I imagine, in the amazingly polite society
  of CS80 folk, this could be worked out.

  We could at least have fun brainstorming what features a KAS
  replacement board would bring:

  MIDI in/out
  Disable bad/out-of-tune voices
  Auto (or least least assisted) tuning
  Mono mode - with various key priority
  Unison mode (dynamic?)
  Different key assign modes
  Different glide/gliss curves

  A lot of stuff I can think of would also require replacing the TSB and
  TKC board. Basically, you end up replacing all the electronics under
  the keyboard, which would be great, and theoretically not too complex,
  but a lot of design work and rewiring!

  Dream away!

  Is this true? I don't have a CS80 around at the moment, but I could
  swear, at least in Sustain-I mode, that if you are holding eight keys
  down, it ignores any subsequent key presses.

  Just looked at this. Maybe I don't want to ever work on one of these
  and will stick with the (relatively) simple CS80 :^)

  Do you have mono and/or unison modes? For mono, you'd want choices of
  high-note priority, low-note, and last note.
