great suggestion (duh). makes sense for fine tuning vibratos,
etc, such as moving a vibrato(lfo) to stay above the osc pitch
rather than symmetrical all the time. but would this work for
negative offset values such as vibrato movement BELOW the
osc pitch can you get a negative value from the CV source to
mix w lfo
