FatMan Mod & Oscope Fun

[Scott Gravenhorst]

I'm on a week's worth of vacation so I started some DIY.
Finished a new hard sync mod for the FatMan.  Instead
of injecting a pulse to the integration cap of the VCO,
I took advantage of the 555's reset input.  Through a
switch I simply routed the VCO2 555 pin 3 (output pulse)
to the VCO1 555 pin 4 (reset input) and voila.  I believe
that this is true hard sync.  My other method was a form
of soft sync.

The new mod is on http://www.teklab.com/~chordman

It's under "simple circuits", FatMan New Hard Sync.

I verified the waveform using my new oscope and then of
course, I start playing around.  I put probes on the
filter input and output, trigger from filter input and 
observed the cool things that happen.  rez at max, play 
with cutoff, while listening, of course.
