[sdiy] keyboard schematics

[fmg]

Sam,

I'm looking at Moritas keyboard schematics of your site (moritaKB.gif)
and wondering if you can help me with some questions.

1. Do you know the value of the Rs in the voltage divider (or the 
numbers of keybrd contacts), or the value of zeners in both sides of
this chain ?
2. What say the vertical text that point to the 4558 ? (the one which
have the + input to the keyboard)
3. The output of the other opamp of this 4558, goes to the 10k of the
741 immediatly below the S&H buffers ?
4. What say the text below this 741 and the S-T that follow it ?

Sorry to be so inquisitive :-) I saw the PE msonic rf keybrd, the
moog 952, and the Morita's, and liked this.
