Speaking of LFO sync...

This patch creates a pseudo-fractal sawtooth modulation source.  The
ingredients:

(2) 320 VCLFOs - If creating sine, triangle or square shaped fractals
you could also use the VC section of the 390 micro LFO.

(1) 300 VCO - Another 320 would have been better, giving VC of the
fractal shape, but I only had two.  You could also use a 390 uVCO here.

(1) 830 Dual Mixer - You could also use the 850 Pedal Interface as a
bias/modulation source.

(1) 910 or 940 Multiple

(1 optional) Oakley OMS-802 Mixer/Triple Attenuator, configured as
distributor, 1 in, 3 out.

Patching

VCO Sawtooth to Mixer input 4
VCLFO #1 Sawtooth to Mixer input 5
VCLFO #2 Sawtooth to Mixer input 6
VCO Pulse to VCLFO #1 Sync input
VCLFO #1 Pulse to VCLFO #2 Sync
Mixer out 1 to Multiple
Multiples to VCO FM2, VCLFO #1 FM and VCLFO #2 FM
Mixer out 2 is the fractal modulation source

Settings

VCO set near its lowest frequency
VCLFO #1 set from 3x to 10x of VCO frequency
VCLFO #2 set from 3x to 10x of VCLFO #1 frequency
Enable bias on Mixer
Generally mixer inputs 4, 5 and 6 are set so that input 4 has full
amplitude, input 5 has 1/2 to 1/5 that amplitude, and input 6 has 1/2 to
1/5 the amplitude of input 5.  But you can try anything here.

Option #1:  
Signals to mixer inputs 1, 2 and 3 enable modulation of the fractal
frequency.

Option #2:  
Routing mixer out 1 to the Oakley Mixer/Attenuator allows different
ranges of control for each fractal element, using the Oakley as a 1 in 3
out attenuator.

Option #3:  
With a third VCLFO instead of VCO, add another 830 Dual Mixer and use
the first stage for waveform modulation and bias.

Operation

This patch creates overlapping sawtooths at staggered frequency
intervals for a waveform that has microscopic replications of itself.
This creates a very complex modulation source, but still controlled.
The sync inputs synchronize each successive microscopic waveform to the
next lower frequency in the fractal landscape.  The mixer bias controls
the frequency of the pseudo-fractal waveform.
