Module A-190-7(1U) is the 1U version of the A-190-9. The functions of A-190-7 are exactly the same as for the A-190-9. Only the positions of the controls and sockets are different because of the 1U format.

Module A-190-7 is a simple Midi-to-CV/Gate interface. It is planned for applications where the more sophisticated functions of the other midi interfaces of the A-190-x series are not required.
These are the most important features of the A-190-9:

• simple monophonic midi-to-CV/Gate interface
• 3.5 mm stereo socket as midi input, can be internally adjusted to one of the two versions of the 3.5 mm midi standards by means of two jumpers.
• the midi input can be normalled to the midi output of another A-100 module by means of Arduino cables, provided that the other module features an internal midi output (e.g. A-155-2, A-198-2) 
• particularly the CV voltage of the A-155-2 can be output in quantized form
• three CV outputs, 1V/Octave (3-fold multiple)
• CV output range 0...+5V
• the CV output is controllen via midi by note messages, the midi reference note number 36 corresponds to 0V CV
• the module responds only to the note numbers of midi note-on/off messages (no velocity, no pitchbend, no control changes, no clock)
• the scale of the CV output can be adjusted by means of a multi-gang trimming potentiometer (factory setting: exactly 1.00V/octave)
• two gate outputs (2-fold multiple)
• gate level 0/+10V
• LED display for gate status
• factory settings: midi channel 1, midi reference note 36 (for 0V CV), the midi channel can be modified by the user with the help of some solder joints
• can be used also as a simple breakout module for midi in/out (e.g. for A-155-2, A-198-2)
