The Obesifier circuit turns a single VCO into a real nice drone.
There's samples on the site.<br>

I've got a simpler with six stages version and two modulation inputs
without the onboard modulation LFO's (it still has a fixed LFO for each
stage).<br>

<div>Hello All,</div>
<div> I'm looking to build a module that will be used to generate a
drone tone to under current the main theme in a musical pieace. I've
looked at using 555 timer to CD4024 divider, a dozen of those would be
cool, but not very flexable once tuned up.</div>
<div> How about CD4046 PLL's using the divider scheme, more flexable,
but only square waves. Hum....... A bank of Rene's CMOS VCO's ........
a little complex but very useful.</div>
<div> Any ideas? Hope I'm not being too vague or.... well, never
mind. Any and all ideas will be appreciated.</div>
<div> </div>
<div> Thanks,</div>
