SH-101 and LFO sync

[DCMagnuson at aol.com]

Hi everyone,

I've been busy modifying a Roland SH-101, already adding a pot for the unused 
triangle wave from the CEM3340, 2 audio inputs, and a second LFO.  

I was wondering if anyone knows a good way to sync the new LFO to the stock 
one.  I can see on the schematic that TR4 looks like it resets the timing cap 
on the LFO.  The problem is that my scope needs some work, so I can't look at 
the waveform used for reset.  

If anyone can offer any tips on syncing this with my new LFO, that would be 
great.  BTW, the new LFO is very similar in design... a 2 opamp tri/square 
LFO... I think I used Tom G's LFO-1A if I recall correctly.

Also, speaking of sync... I don't have sync on any of my LFOs in my modular 
yet.  Can you get interesting effects by syncing your LFOs to your VCOs?  If 
so, I may want to use the hard/soft sync inputs on the 3340 as well.  Any 
benefit to doing this?

Thanks in advance,

Dave Magnuson
