The CV of our interfaces (A-190-X) can be modified very easily to
1.2V/octave by replacing some resistors by other values. For some of the
modules the 1.2V maybe even within the adjustment range but I'll have to try
it out first.

And the additional trigger signal is nothing but a capacitor connected to
the gate if I'm not wrong. If someone has details about the Buchla style
gate/trigger please let me know. I could not find anything in my records.
Then I can decide how much effort it is to offer such a module. But I'm a
bit cautious: in the past we offered a special version of the MCV4 for EMS
synthesizers (0.32V/oct and EMS style gate/trigger). We sold less than 20
over a period of more than 3 years.
