I recorded this during the Spring 2021 offering of ECE4450: Analog Circuits for Music Synthesis, but this material will likely be appropriate for future offerings as well.

Thank you for posting all of these videos! I love your presentation style, making things very easy and entertaining to follow!

[@Lantertronics]

Thank you for your kind words!

I graduated EE a while ago, but always felt that my university was missing a synthesizer-focused course! Thank you for providing the world with this often overlooked side of electrical engineering!

Thank you Aaron for the video!

I've always left the non-inverting input grounded, and then sum a DC offset into the inverting input. Any reason to go the other route? (other than possibly needing an additional reference voltage of course)

[@Lantertronics]

Either should work fine.

Very well presented video! I'm wondering what advantages this approach has versus putting a DC blocking capacitor in series with the signal coming out of the oscillator core, given the extra component count, where can I learn more about this?

[@Lantertronics]

I *think* the main thing is that a DC block is going to form a highness filter, that will potentially attenuate some low frequencies.

I have to thank you too for this videos. They are absolutely great.
Can I ask you about what literature do you recommend to learn more about audio circuitry (analog as well digital)?
Thanks :)

[@Lantertronics]

Best general book is "The Art of Electronics" by Horowitz and Hill. For audio in particular I recommend Douglas Self's book "Small Signal Audio Design."

@@Lantertronics thanks! I‘m gonna take a look :)
