hey yves
first of all your site has been a great help and i love some of the circuits
that iv´e built from your page like the steiner filter.

im really interested in this module but would like to add sync input (retrigger)
ive used this circuit (attached) that tim parkhurst came up with for his 8k lfo for a few different lfos with success,
i was wondering would i only have to put the circuit on C6
or also on C7 on the quad lfo ?
thanks
Fridfinnur

Synching this lFO is not easy indeed. To stop the oscillator it is sufficient to act on a single integrator only, since it's the chaining of both integrator that makes it possible to oscillate.

Still I am not sure that you won't have problem to restart the oscillation since in its normal configuration the circuit enters slowly into oscillation when the CV is low. I am afraid there will be lag with a synch circuit.

Well in my opinion (though I have never tried) is this VC-LFO is not suited for synching application.
