connecting an A-178 theremin module to an Oberheim Xpander

2008-01-11 by baumont987

Hi,

I'm planning to buy 2 A-178 modules to control my Oberheim Xpander
with CV/Gate (and using the CV to MIDI feature of the XP to control
other instruments).
Are the outputs of the A-178 fully compatible with standard 1V/oct
CV/gate or it is specific to the A-100 system ?
On Doepfer website, about signals in A-100, it is specified:
* Control voltages, as produced by modulation sources like the LFO and
ADSR, are from -2.5 V to +2.5 V (5 VSS) for the LFO, and from 0 V to
+8 V for the ADSR.
* Trigger or Gate Signals (...) are typically from 0 V to 5 V

Is the CV Ouptut of the A178 a trigger-like output or will I need to
add a 2.5V continous signal to the CV output in order to get a
standard CV/Gate voltage of  0-5V ?

Thank your for your answers,
Greg.
