Module A-190-5 is a four voice Midi/USB to CV/Gate interface. For each voice a pitch control voltage (CV1, 1V/octave standard to control VCOs), a gate output (to control envelope generators) and two additional control voltages (CV2, CV3) are available. The two additional CV outputs can be controlled by Midi velocity, volume, modulation, after touch or free assignable Midi controllers.
The resolution of the CV outputs is 12 bit and the voltage range is 0-10V.
These modes are available:
- four voice monophonic (i.e. to control four monophonic voices by four succeeding Midi channels)
- four voice polyphonic (i.e. to control four monophonic voices by one Midi channel)
- two voice polyphonic (i.e. to control two monophonic voices by one Midi channel)
details about all available modes of the current firmware version can be found in the user’s manual: A190_5_man.pdf
The mode is selected by means of momentary switches and is shown in the LC display. Certain parameters of each mode can be edited (e.g. the midi channel(s), the midi reference note for 0V CV, assigned controllers for CV2 and CV3). The parameter values (e.g. midi channels) are shown in the display and can be modified by means of the momentary switches. In Play mode the LEDs of the first four switches display the gate states.

Updates and bug fixes can be installed by the customer via the USB interface if applicable.

Attention: All midi data on the Legacy Midin and the USB MidiIn are output directly to the Legacy MidiOut and the USB Midiout. In the case of a combination of Legacy Midi & USB Midi, this can sometimes be useful.
But if events are mirrored back directly from the USB-In to the USB-Out, this is actually not very useful, rather it results in a real danger and a problem.
If the DAW that sends events to the A190-5 gets them back directly via a midi-in from the A190-5, then we have a midi feedback loop.
What exactly happens then depends on many factors – but mostly nothing good – the DAW, or the device then seems to do strange things, hang up etc …
At the moment there is no way to fix this on the A190-5, this will be addressed in the next update.
On the part of the DAW it must now be prevented that events come back to the same track from which they were already sent to the A190-5, in which there is a ‘midi to’ connection to the A190-5. ..
