Dear all,

I’d like to make my first drone synt, following the principle of the simple oscillator (by LMNC).  
The synth will have multiple oscillators, and each one will have a pitch know, a tone know and a volume knob. I tried to draw out a scheme for two oscilators.

Two questions: Will it work with this scheme?  
And what potmeters should I have for the volume knobs?

Thanks!

For the tone pot, the cap need to go to the middle pin too 🙂

for volume pot between 10K and 100K must work

indeed, I forgot that one.  
Thanks for your help!

As I read somewhere, I would need some resistors to add to the scheme in order to have those volume knobs there. Any suggestions on that?

Can I have linear potmeters for the volume knobs?

Thanks!

@jdm add a 100K between each volume pot and the mix point .

here it’s with a 47K but look at this passive mixer

and for the volume pot, some audio will be better but linear work 🙂
