Description

A-190-4 is the replacement for module A-190-1 which is no longer available. The functions of A-190-1 and A-190-4 are nearly the same (Midi In, Midi Out, CV1, CV2, Gate, Clock, Reset). But the operation of the A-190-4 has been improved because a 3-digit LED display is available. The current values of all parameters (like Midi channel, reference note, clock divider) can be read back and modified by means of up/down buttons. In addition A-190-4 is equipped with an USB interface and the external +5V supply is no longer available. Consequently the additional charges for the 5V adapter fall away.

It has two CV outputs, which output control voltages from 0 V to +5 V so that you can control not just the pitch, but also another voltage-controllable parameter.

CV1 is hard-wired to receive Midi note messages and convert them into a 1V/octave compatible control voltage. As a rule, CV1 will be used to control the pitch of one or more VCOs which follow the 1V/octave standard. In addition, the A-190-4 allows for portamento (glide) and pitch-bend, and provides a software LFO for CV1.

The second CV output CV2 can assigned to Midi velocity, after touch or your choice of MIDI controller. It can be used for voltage control of any suitable module (eg VCF, VCA, etc.).

A-190-4 has a Gate output available which is usually connected to the gate input(s) of one or more envelope generators (ADSR).

The module also has a clock output available which is 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.

The Reset output is controlled by Midi Start/Stop. A Midi Start or Continue message turns Reset to low, a Midi Stop messages makes it go high. If desired the polarity can of the Reset output can be inverted.

From the factory the voltage levels for Gate, Clock and Reset are +5V. By means of a jumper the levels can be changed to +12V. Within the A-100 both levels are possible. If you want to control other devices please refer to the user manual which level is required.

Specs:
200 mA +12V
40 mA -12V
0 mA 5V
10hp
50 mm deep

Note: The supply current fluctuates between about 80 and 200 mA according the number of illuminated segments of the display. 200 mA corresponds to the worst case “888”.
