[sdiy] LM13600 VCO

I believe the answer to this one is "don't do it", but I'll
ask anyway:

A tri/square VCO can be made using an LM13600, but one
amplifier is used as a schmitt trigger.  An opamp could be
used for the schmitt trigger.  Is it a bad idea to use an
LM13600 and an dual opamp to make a dual VCO?  I'm thinking
that there would probably be coupling problems that would
result in soft sync between the two VCOs.
