3. Basics
Module A-192 converts up to 16 analog control volta-
ges (CV) in the voltage range 0...+5V into 16 MIDI
controllers (exactly: MIDI control change messages).
The MIDI channel for each controller can be selected
(1-16). E.g. 16 different controllers on the same MIDI
channel may be chosen, or even the same controller
number on different MIDI channels. All mixtures of
controller numbers and MIDI channels are possible.
The term controller is not quite correct as A-192 even
supports similar messages like after touch or pitch
bend, as well as most of the common RPN resp.
NRPN controllers and most of the GS, XG control-
lers resp. XG sysex messages.
The active input voltage range is 0...+5V. Negative
voltages and voltages above +5V are not converted.
A protection circuit on each input prevents the da-
mage of the module as long as the voltages applied to
the inputs are in the range of -12V...+12V. This
means that within the A-100 system it is not possible
to damage the A-192 module as the output voltages
of all A-100 modules are within these limits.
If negative voltages (e.g. from a LFO) or voltages
above +5V (e.g. from an ADSR) are to be converted
an attenuator / offset generator module (A-129/3) has
to be inserted between the voltage and the A-192
input. The A-129/3 enables the addition of a positive
voltage and the attenuation of the input voltage so
that the output (= input of A-192) is in the required
range of 0...+5V.
The assignments of the 16 CV inputs to MIDI control-
lers and channels is defined in 128 presets. A preset
is selected permanently with an 8-pin DIP switch on
the pc board or temporarily via incoming MIDI pro-
gram change messages on the MIDI master chan-
nel.
You will find a table of all factory presets with the
corresponding DIP switch settings in the appendix of
this manual. If none of the factory presets is suitable
for your application you may program one or more
new presets with the editor program which is avai-
lable for free on our web site www.doepfer.com
.
(same as editor program for Pocket Control). The
program runs on a PC under Windows 95/98/2000.
For a small extra charge (about US$10.00) we also
have available the OEM version of Emagic’s Sound-
diver (universal editor program) suitable for both PC
and Mac.
