Module A-192-2 contains two independent CV/Gate-to-Midi/USB interfaces. For each of the two sub-units these inputs are available:
Gate Input (min. +5V)
CVN Input (defines the Midi note number), 1V/octave standard, range 0...+10V (i.e. 10 octaves)
CVV Input (defines the velocity value assigned to the Midi note message), can be used alternatively for Midi volume (CC#7), range 0...+5V
CVC Input (free assignable to any Midi control change number), range 0...+5V
For both sub-units a common CV Transpose input is available (1V/octave, range 0...+10V). The voltage applied to this input is added internally to CVN before the Midi note number is generated. It can be used e.g. to transpose two sequences simultaneously by one voltage.
Factory settings:
Midi reference note for CVN = 0V: 36 (C)
Velocity mode (CVV generates velocity data)
Midi control change number assigned to CVC: #1 (modulation)
Sub-unit 1: Midi channel 1
Sub-unit 2: Midi channel 2
The factory setting can be restored by operating the learn button of the corresponding sub-unit during power on (i.e. the button has to be held down while the A-100 system is turned ON).
Typical applications:
Conversion of analog sequences into Midi/USB data (e.g. A-155)
Generating random Midi sequences (e.g. with CVN coming from A-118 or A-149-1, Gate e.g. from an LFO)
Generating Midi control change data from analog voltages
If bipolar or negative voltages have to be converted an offset generator is recommended (e.g. A-183-2). There is also an internal jumper available on the A-192-2 board that adds about +5V to the incoming control voltages CVN, CVV and CVC as soon as the jumper is installed.
