MIDI-CV/SYNC Interface A-190
1
1. Introduction
The A-190 is a MIDI-CV/SYNC Interface, with which
you can control any A-100 Module which has CV and
gate/trigger input sockets by MIDI.
The A-190 has two Digital-to-Analogue converters
(DAC for short), which put out control voltages from 0
V to +5 V, so that you can control not just the pitch, but
also another voltage-controllable parameter on the
A-100.
DAC 1
is ‘hard-wired’ to receive MIDI
note messages
and convert them into control voltages available at CV
output socket CV 1. The DAC has 12-bit resolution,
which gives excellent tuning resolution (in steps of
1/4096th). As a rule, DAC 1 will be used to control
VCO pitch
.
DAC 2 can be assigned to your choice of MIDI con-
troller
. This DAC has 7-bit resolution (1/128th steps).
Its output is available at CV 2, and can be used for
voltage control of any suitable module (eg VCF, VCA,
etc.).
The A-190 also has a clock output, controlled by MIDI
clock. This can be divided down to provide a variety of
clock outputs, and enable older sequencers or drum
machines to be synced to MIDI.
A Reset Output provides control of the A-160 / 161
Clock Divider / Sequencer or can produce MIDI-
synchronised gates (for instance on an ADSR). MIDI
START or CONTINUE messages make the voltage at
the Reset output go low, and MIDI STOP messages
make it go high.
In addition, the A-190 allows for portamento (glide)
and pitch-bend, and provides a software LFO. These
functions can all be switched on and off or altered by
MIDI controllers.
All control parameters can be saved in non-volatile
memory
.
H The A-190 needs an additional power supply
(+5 V / 50 mA) for connection to the system
bus.
To install the A-190 please look at the
important information on p. 4!
