Thanks for info, I didn't know. Who knows why key assign algorithm is like this, maybe some kind of technical limitation? I don't see any logical reason why on 8 voice instrument one voice shouldn't play except when 8 keys are pressed.

But anyway it's strange, because if there's only 7 voices playing, and one voice card doesn't work, then each 7th press of the key will not sound, I suppose. On my CS each 8th didn't sound.

Thanks Laurie, this is what I meant. If you always heard 1 voice was silent simply means it was one of the first 7 voices.

Voice 8 on both panels will not sound in rotation on any working CS80 unles you hold a finger down before you  press another key which will be 8 ....

you will get 1234567 1234567
but if you go 12(3-hold) next one is 8   4567

the 123 order only works on start up....
as soon as you play a chord the order changes....

voices do rotate in both sustain modes...

I'm glad you liked it.

There was no time in the studio to set the instrument better, I had to play something just after they brought it, and before the recording there was no rehearsal, that recording was done live. And I forgot to show ribbon in that studio recording hectic... Now, when I have instrument back in my studio, I could get much better sound from it. It only needs a little bit of tuning, I'll do it later.

Concerning voices - I don't think I fooled them, if I understand that instrument well, voices rotate and each new key press goes to the next voice card. (It is obvious because before calibration each new key press of the same key started the sound with other pitch, timbre, even envelope...) That was the reason why each eighth voice in lower synth didn't worked before the repair - one voice card was out of function. Regardless if I played one voice successively, or pressed 8 keys - always one voice was missing.

So I don't understand well what you mean - why there should be always one voice which doesn't play? All eight voice cards must work always, be it in monophonic or polyphonic play. Or am I totally wrong?

Of course there's also Sustain I and II modes, in one of them probably voices don't rotate when played monophonically, and only the last note gets sustain.

Very funny program thanks !
I wish my tech would do me the 49th minute moment every time he repairs a synth of mine :)
Maybe I should show him that they do it better in Japan :)

And I quite enjoyed your final demo. Excellent sounds and performance there. Not only all the voices work but the calibration seems to be very accurate. That's one of the main recurrent issues on the CSs...
Now you realise you fooled them all by playing each voices with 1 finger only right ? Playing like that the CS never allows you to play all voices. There is always one that is not playing. To ear them all you need to keep keys pressed...
