Subject: fm and sync pitch

When talking about sync pitch-which is the one you hear-the slave or
the master?

If it's the slave, then setting the sync pitch changes the pitch of
the note you hear.

Here's where things can get weird. The algorithm determines whether
the slave, the master, or both get affected by fm. Pretty straight
forward. The sync pitch depth and sync pitch source modify the
frequency of the slave oscillator (fm). Then there's the sync pmod
sw, that lets you decide whether the slave or the master is affected
by VCO 1 pmod dp.

Are we lost yet? God love the manual-it's virtually useless.So it
looks like the slave frequency and the master frequency can be
modulated, independent of each other.The slave wave can be modulated
by fm, by VCO 1 pmod dp, or by sync pitch source. What happens if you
pick D-all of the above? Just what goes on then?

The master frequency can be modified by VCO 1 pmod dp or by fm. I
assume it can be modified by both at the same time.

To complicate things even more, the frequency can be modified by fm
source 2 and fm source 1 modifies how much fm depth you get over time.

We should have a new patch contest. Everyone take all this fm stuff,
whack the hell out of the pitch envelope, add some insane portamento
and see who can make the most seasick inducing patch.
