We discussed the additional VCA option for the A-143-9 and have another suggestion:

How about a separate quad VCA module with one common control (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.

Tell me what you think.
