1. Introduction

The A-190-4 is a MIDI-CV/SYNC Interface, capable to
control any A-100 Module via MIDI that provides CV and
gate/trigger input sockets.

The A-190-4 has two Digital-to-Analogue converters
(DAC for short), which put out control voltages from -3V
to +10V (CV1) and 0V to +10V (CV2), so that you can
control not just pitch, but also another voltage-controllable
parameter of your synthesizer.

DAC1 is ‘hard-wired’ to receive MIDI note messages and
convert them into control voltages available at CV output
socket CV1. The DAC has 12-bit resolution, which gives
excellent tuning resolution (in steps of 1/4096th). Usually,
DAC1 will be used to control VCO pitch.

DAC2 can be assigned to a MIDI controller. It has also
12-bit resolution in order to allow smooth parameter
changes. Its output is available at CV2 socket, and can
be used for voltage control of any suitable module (eg.
VCF, VCA, etc.).
