[sdiy] Oscillator sync schemes

[Cynthia Webster]

Hi Michael!

First let me thank you and congratulate you on your clever purchase of 
Zeroscillators :)

You know what is a really fun technique is to valve or control the flow 
of the sync signal coming into your oscillators with a DC coupled VCA or 
Cynthia Low Pass Gate.

depending on the frequencies of the external controlling oscillator, you 
can set the relationship to make a huge increase in pitch when the sync 
is the hardest, and it will play successively lower harmonics as you 
close or valve
the VCA.  Thus, by playing the CV of the VCA you are thus playing 
harmonically related melodies - all without ever touching a tuning knob, 
etc.

Try the above with any oscillators and see what happens.  
SignalOutput-to-VCA-to-SyncJack

Also daisy chaining several VCOs can be interesting such as

SyncJack-to-SyncJack-to-SyncJack-to-SyncJack-to-SyncJack  or

SignalOutput-to-SyncJack-to-SyncJack-to-SyncJack-to-SyncJack or

or weave a crazy Celtic knot of manipulable synchronicity with several 
independent VCAs such as
SignalOutput-to-VCA-to-SyncJack-to-SignalOutput-to-VCA-to-SyncJack-to-SignalOutput-to-VCA-to-SyncJack

cross syncing cross modulated oscillators ought to be very interesting, 
say modulated by a joystick with the SyncVCA valved by one axis, and the 
cross mod IndexVCA valved by the other?

I cannot wait to try a Continuum Polyphonic Controller with several 
Zeroscillators, and having the tuning of the ZOs and the Modulating 
Oscillators controlled separately by the two axis of the Continuum, oh 
sweet!
You could also use the new Y axis to control the depth of sync between 
them all which might be kinda' scary sounding!
