why not posting something when one has an hangover and nothing else to do

adapt the values of pot and caps to your needs


Permette
Really nice from you to share your ideas.
I love your circuits.
Thank you very much !
Regards.

I don't have time to breadboard this Quadrature yet, but what if I don't use a stereo pot ? Would it be like RISE and FALL pots ?
Thanks.

Cheers !

Very interesting question hmmm.....

Hi very nice example of lateral thinking as is your trademark thumbs up

Still I think it´s slightly more complex than a state variable oscillator with inverter (which is sine of course)...if I am not totally missing something important!

eek! shame - i dont know much about state-variable-oscillators, which are the most widely used ones? do they work fine as LFO?

Permette
if u dont use a stereo pot u would set with pot1 the frequency and with pot2 the amplitude of 90° and 270°

happy easter for us all

Thanks for your answer, got it !
Yes, happy Easter !

Cheers.

Yes, you know it, look here Miley Cyrus

Cheers, really like your stuff hyper
gabba@gabi
ah, i see i see
and thx mate,

i had a little think about the circuit and if the simulation dont lie - there is the possibility to have a flexible phasediff - but only 90° wide (for now?!)

in this combination from 0° to -90° via R9

gabba@gabi
0° to -180° with CV

gabba@gabi
all attempts to make this real triangle failed, cos of amplitude drift in the 45° subcircuit
found a book on the HD which ive never read and found the answer: a feedback resistor

find attached the simulation of it, and the (simulation) adaption to a VCO and a TZVCO

180° and 270° not icluded
