The linearity may be bad with the 4046, but the real problem with the
'portamento' effect will be the loop filter.  If the filter is set too
low in freq, it will cause lag.  If set too high, it will cause a
'sproinging' over-under-over-under shoot problem.  the characteristics
of this may change slightly with better linearity, but the real
problem is the filter.
