There is one aspect, nearly everyone forgets when talking about tracking
of V/Hz synths:
The range of 1 Volt in the high frequencies may be only a few notes, in
the lowest notes 1 Volt may correspond to more than two octaves. So some
noise on the CV or mis-calibrating of the interface will have a real big
impact on basslines and will be nearly unhearable with high notes.
