"This utility modules provides switchable discrete CVs with useful intervals such as :
Also for each voice, an external CV can be summed to the stepped voltages. These inputs are intended for connecting external controllers such as a keyboard or a sequencer. Note that the input of voices 2 and 3 are defaulted to the previous input. For example if one connects a keyboard CV to IN #1 then this CV is echoed on the two others voices. But if one connects three different CVs on the three inputs, then each voice is only driven by the corrsponding input." - Yves Usson
