IMHO, this would be most interesting if this Q-VCA could also be
connected to the A-149-9 behind the front pannels with a flat-cable
(like A-149-1/2 and A-160/1), omitting the need for 4 extra patch
cables.

It would offer the combined benefits of efficient prepatching
functionality as well as modular versatility. Without connecting
this "under water" flat cable, this VCA could then be used for many
other modules beside the A-143-9.

Is this perhaps a feasible idea

(manual + ext. CV) for all VCAs. This module could be used even for
other applications than only for the sine/cosine outputs of the A-
143-9. E.g. for the other four-fold modulation modules of the A-143-
x series like the quad AD, quad ADSR or quad LFO. A separate quad
VCA module would not be very much more expensive than four VCAs
integrated into the A-143-9 (4 additional sockets plus a separate
front panel). After all the quad VCA section of the A-143-9 would be
also a separate pc board containing the four VCAs. If we add four
input sockets and make a separate front panel we would have a
separate quad VCA module which is from my point of view more
flexible than four VCAs only for the A-143-9.
