[sdiy] Drone Synth

[Steve Allen]

Ah... yes,
 Think I'll go with the CD4069 vco's and the Obesifers. Wow if that's not a wall of sound then I'm anemic and in need of some....... never mind.
 Thanks Scott.

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

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).

Hello All,
 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.
 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.
 Any ideas? Hope I'm not being too vague or.... well, never mind. Any and all ideas will be appreciated.
 
 Thanks,
   Steve
