Yamaha CS80

FYI, there's a great thread going over at the Harmony Central boards:

http://acapella.harmony-central.com/showthread.php?2460185-List-of-Synthesizers-featuring-rare-features...-keep-me-updated

It's about special/rare keyboard features like poly-aftertouch, release velocity, ribbon controllers, etc.

I just put in a couple of comments there, including about the (as far as I know) unique Sustain I/II modes. Does anyone know of any other keyboards, besides the CS50/60/80 that have this ability to have a long release time but have new notes cut off old ones? I think it's an amazing feature of the CS80 and have never seen it anywhere else.

As I wrote, I think it would have to be done at the sound engine side of things. I don't know if it would be possible on a MIDI controller. I don't think there's any MIDI message to cut off sustaining notes. I don't even think a MIDI panic would do that.

David,
It IS possible to emulate Sustain 1/2; I'm doing it actually; it's like you build the MIDI assignment, not the audio part ;-)

I have once modified a Crumar Performer to behave like this.

JH.

the CS sustain I feature is uniqe as it separates oscillator from pitch modulator upon release...but others can do somewhat similar....
The Ensoniq SQ80 has polyaftertouch as well as 2 types of pitch bend...... all notes, or only notes held..... in notes held mode, pedal sustained notes are not affected from the pitch wheel while key down notes are bendable....you can also pedal hold sounds and change to a new preset keeping the old patch in play untill release....avoiding those silent moments between patches...

I realized a little bit ago that I didn't know how the CS80 did the
Sustain I/II trick. So, I've been looking through the schematics - and
I'm still confused! I only see the Sus I/II switch going to the SH
board. This explains the Sus I/II behavior of glide continuing after
letting go of keys in Sus I but freezing pitch in the middle of a glide
in Sus II (or is it the other way around??). However, it doesn't
explain how notes get cut off. I thought I was onto something, but it
was just the mixing of the Sustain slider on the left-hand panel (PN3)
with the programed VCA and VCF release voltage going to the M cards.
This circuit is on the Sub board. Where did I get lost (which is easy
to do on the giant schematic)? I don't see the Sus I/II switch
connecting anywhere else.

By the way, I wish the CS80 didn't freeze the glide in Sus II mode. I
think I might temporarily disconnect that wire to hear how it sounds
with glides finishing in that mode.
