Yes- I concur with Jonbenderr on all points.  I don’t know the Arturia’s output range offhand, but you will want to match its range to the Misha CV In range (or match Misha’s range to its range). Come to think of it, Misha’s CV in range defaults to 0-5V, so unless you’ve changed some defaults you should be able to reach all the intervals (-4 to +4)

Sometimes keyboards have an octave change key which you might have to use to get the entire range

Anyway, having said all that, MIDI might be a better option for you.  Triggering the Misha with MIDI also gives you velocity sensitivity, which might be desirable. Using MIDI requires getting a “type A” conversion cable such as this one:
