The A-190-4 is a MIDI/CV interface module with outputs for gate, clock, reset and two control voltages for notes and control data. The module can receive MIDI data either via USB or via MIDI In. It is operated using a display and four buttons.
The two CV outputs deliver voltages in the range of approx. -3V to +10 V (CV1) and 0V to +10V (CV2). CV1 is primarily for pitch control according to 1V/oct, this output is permanently assigned to incoming midi note commands. In addition, a portamento (glide) and a pitch bend function, as well as an LFO are implemented software-wise in the A-190-4, which can be switched on/off or controlled by means of corresponding MIDI control data. Velocity, After Touch or any other MIDI control data can be assigned to the CV2 output and used for controlling other functions (e.g. VCF, VCA, etc.).
Additionally, a gate output and a clock output are available. The frequency of the clock output can be adjusted. A reset output is also available. This is controlled by the midi commands Start and Stop. When a midi start signal arrives the reset output goes low, when a midi stop signal arrives the output goes high.
By factory default the voltage levels for gate, clock and reset are set to +5V. With the help of a jumper they can be changed to +12V if needed.
The module works in USB mode as USB device or slave. It has no USB host functionality (such as computers or laptops with a USB-A port).

WIth a long trajectory building synths, MIDI keyboards and designing bespoke devices for music pioneers Kraftwerk, Dieter Doepfer decided to design his own modular synthesizer in 1995 based on existing electrical and mechanical specifications of lab equipment he used during his years at university. The official presentation of the system at 1996 Frankfurt Musikmesse caught everyone by surprise and created lots of interest. After Doepfer published the specifications on his website, many instrument designers and engineers saw the potential of the new Eurorack format. Doepfer continues expanding their catalog of over 200 modules (and counting), operating from their modest offices in the outskirts of Munich.
