DOEPFER/A-190-3V USB MIDI CV Interface 1

DOEPFER / A-190-3V USB MIDI CV Interface 1

Variations

A low-cost USB MIDI to CV/Gate interface module from German synthesizer manufacturer Doepfer. It's a modular version of their Dark Link MIDI to CV/Gate interface.

The A-190-3 USB/MIDI-to-CV/Gate Interface is a low-cost USB MIDI to CV/Gate interface module. It features four CV outputs and one gate output. The A-190-3 is a modular version of the Dark Link MIDI to CV/Gate interface.

Input/Output and Control
• USB
• MIDI Input
• Learn Button
• Gate Output (with LED for gate indicator and Learn function) (0 / +5V)
• CV1: MIDI Note Message, 1V/Oct (0 to +5V)
• CV2: MIDI Pitch Bend (-2.5V to +2.5V or 0 to +5V, selectable by internal jumper setting)
• CV3: MIDI Velocity (0 to +5V)
• CV4: Freely assignable MIDI Control Change Number (0 to +5V)
• Glide Control (Portamento function for CV1)

Other Features
The MIDI channel, reference note, and MIDI control change number for CV4 are set using the Learn button and LED.

By setting two jumpers, CV1 and Gate can be connected to the corresponding lines on the A-100 bus. VCOs such as the A-110 and envelopes such as the A-140 can be controlled directly via the A-100 bus. There is no need to patch CVs or gates on the front panel. CV1 is buffered, eliminating the need for additional bus buffers such as the A-185-2, and allowing for precise pitch control of multiple VCOs.

The gate voltage can be set to +5V or +12V using two jumper settings. A-100 modules can use both voltages. For modules or devices from other manufacturers, the gate voltage must be set according to the connection destination.

When connecting the gate output to devices using S-Trig, such as Minimoog, a special S-Trig cable is required.

By connecting CV1 and CV2 to the A-185-2 Precision CV Adder, a pitch bend with adjustable range can be used. CV2 of the A-190-3 connects to the upper input of the A-185-2 where an attenuator can be used. Connect CV1 of the A-190-3 to one of the other inputs that do not have an attenuator.
