[sdiy] EFM LFO5 Sync Help

[Tony Allgood]

>LFO sync is not so easy.  Reset of integrator and reset of schmidt
trigger are both needed.  Mono/Poly LFO does them in a tricky way.

I have LFO sync on my little-LFO, and the LFO in the VCF-1 too. I do
both of them slightly different, but the principle is the same. I use a
one analogue switch to short the timing cap and another to force the
schmitt to go positive.
