actually, i would not want to modify my A190, as i want to be able to use it for my (countless) 1 volt/oct needs too. a converter module, as i suggested, would be best...

go Dieter!

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.



Best wishes
