[sdiy] Drone Synth

[Peter Grenader]

Saws?  did you say SAWS?

As I conscientious  harmonic objector, I take this out and out refusal to
recogonize THE POWER OF THE SINE, my brothers...in your mention of the
ultimate drone-doer.

If you go this route, I highly recommend the tri to sine shaper found in
electronotes vol. 1, the one that forces the triangle into the 'ooh-my-gawd'
region of two diodes, then to an FET.  This is by far the best sounding sine
shaper I've ever heard - but ya gotta make a triangle first.

Can you say..258?

If I recall correctly, Scott Gravenhorst has used a PLL to generate saws
from squares. Would that be useful?
 
He's also worked on some kind of divider for creating different intervals
from a master (high speed) oscillator.
 
The above is from memory, perhaps Scott can add some details.

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
