Well, I guess he means I've been working on discrete equivalents for
years. Robert Rich has my rework of the VCO sone as a module; he wants
more of them, so I guess it at least works. The filters I already did.
The VCA is on the charts. The EGs are at least soldered prototypes.
But its is the control system I really want to remake. The key
assigner, glide/protamento logic, and so on. I made a schematic of what
I'd do some years back, and it will change a bit, but it is all
essentially in there. The key assigner is not easily remade as it is a
ternary encoder, using both the +8.5v to 0v and 0v to -6.5v transistions
for the octave and note select. Then there is all that synchronous
clocking of registers they used in random logic to operate the many
analog switches to reduce key velocity/AT to the eight voices. Its the
way they built things back then that simply will never be repeated that
I have to faithfully recapture. I mean, no one is going to put over 200
VCAs in a production synthesizer ever again--the CS80 and the Electone
series in general will be a big chapter in my book, "Why They Built
Things the Way They Did, and Why They Will Never Build Them That Way
Again." ;)
JH is interested in the VCA, so maybe I will get remotivated...
