1v/oct 16-note Keyboard with cv-mixer
This is a 10 HP Eurorack adaptation of the CGS10 ‘mini -keyboard’, It is a 1v/octave pushbutton keyboard spanning 16 semi-tones, so 1 octave + 4 additional semi-tones, based around the 74C922 matrix chip.
In addition, I included a cv-mixer to add control voltage,so it can be used to transpose sequences.
Inputs: CV-in;
Outputs: CV-out, Gate-out,
Controls: 16 note-on keys, 1 tune pot.
