To speak the truth I'd not recommend to copy the A-129 modules as they are. As already mentioned by you more modern VCAs (SSM2164)
instead of the obsolete and expensive Curtis VCAs CEM3381 should be used. And it would be also a good idea to use a better type of
VC slew limiter (not the controller/slew limiter combo with pulsewidth controlled VC switches and lowpass filters). After all it
would be a redesign. Only the filter stages could remain unchanged. Maybe we could collect orders. If 50 orders are reached we may
think about a new more compact vocoder, i.e. an all-in-one unit with analysis section, slew limiter, synthesis section. Each channel
linked via jumpers between analysis section/slew limiter input and slew limiter output/synthesis section so that it can expanded to
a fully modular version if desired by replacing the jumpers by output/input sockets. But I don't want to promise anything as we
still have a lot of projects to be finished.
