Well, the thing is that my Doepfer 5V adaptor broke, so I haven't tested the MT9 yet, but I have ordered one that will arrive today.

MT9:
"Introduction
The MT9 is a MIDI to triggering module. It allows triggering of a range of analogue devices; drum voice modules, envelope modules, analogue sequencers, analogue drum machines, and anything else with a gate, trigger or clock input.
It has 9 separate 5v trigger outputs, so 9 devices can be independently triggered via separate MIDI keys. There is also an ACCent output.

ACCENT
The ACC is an on (5v) / off (0v) output. When velocity of over 80 is received for any of the 9 triggers, then the Accent will go high (5v). Lower than 80 the output will go low (0v). Use this output to control other analogue modules.
Note: it is not directly compatible with the drum module ACC inputs. The naming of this socket is perhaps misleading if you use our drum modules. The drum modules require a different type of accent signal; 12v on, about 5v off. We may (or may not) make an 'Accent' add-on module.

Outputs:
9 independent trigger outs + Accent on/off
MIDI Thru
Power supply:
+5V, GND Doepfer A100 type power sockets"



I believe it's a short trigger signals and this would be perfect for switching the A-150, if the CV input was a trigger input...

Thanks, I really appreciate your help.
Best wishes
Simon
