[sdiy] Idea - Triangle wave DCO core

[Richie Burnett]

Florian, have you ever worked out how the "Metal" setting on the JX-3P 
works?  I haven't sat down and figured it out, but I'm guessing it's 
something like that the master resets the slave's integrator state but 
doesn't reset it's digital counter as well.  Or maybe the other way around: 
The master resets the slave's digital counter, but doesn't reset the 
integrator state back to zero?

I remember looking at JX-3P waveforms on a scope some time ago, and seem to 
remember that the sawtooth waveforms reset back to the middle of the ramp 
rather than the bottom when sync'ed.  All seemed very odd.

-Richie,
