Hi,
long story short, I cloned a moog modular. It’s working great so far.
I saw that synth.com and moon have leds on the oscillators that follow(fade) the sine waveform in the frequency of the oscillator (only useful in lfo mode). Also my sub37 has this leds on the lfo.
I tried some circuits but this is not working so great. I get the led to light up, but it is only 1/3 of the sinus. The whole negative current and a lot of the positive current of sinus is not responding to the led. I have an npn and a pnp transistor circuit and the sinus/triangle output to do that. Also this circuit is somehow affecting the control voltage of the oscillator so the pitch it rising and falling with the fading led and this is very bad and I don’t know from where this is coming.
Does someone have any ideas or schematics, on how to follow a sine/triangle wave with a led with a not fixed frequency?
Thank you
