Re: run util lfo at audio freq

2012-11-09 by spgjmf

yep, looking for the drift and beats between the tones.

ok, guess I order up some pcbs....Rich, what vclfo are you using?
cross modulation is also fun, although my drone machines is more for turning knobs and riding the drift.

while on the topic of the util lfo, - the pulse output on mine does not trigger the trigger inputs on my serger dsg (1985 vintage).
did I wire it wrong? its been 5 years, so I'll have to check...
I meter and get neg dc then pos up to ~3v. I am runnin on +/-12. maybe thats a prob? wud a gate to trigger borad clean it op or a tranny buffer??? the sq wave trigger dsg fine.

need to pull it from the rack....

thanks for all the "feedback"
best
Jeff
