The A-190-9 module is also available in a Vintage Edition and is a simple MIDI-to-CV/Gate interface. It is intended for use in situations where the more advanced features of the other MIDI interfaces in the A-190-x series are not necessary.

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
• 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)
• 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 multiples)
• can be used also as a simple breakout module for midi in/out (e.g. for A-155-2, A-198-2)
