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.
I highly recommend watching Alex Ball's excellent documentary titled: Electromotive -- The Story of ARP Instruments: • Electromotive - The St...
SSM2040 is namely used in the Prophet 5 Rev 1 and 2. The Rev 3 switched to the CEM3320 filter. The newly reintroduced Rev 4 offers both designs. 0:49
Excellent lecture about state variable filters and the outstanding relation to the maths behind it. There is nothing alike on the internet. Thank you so much!
Wow! Need to breadboard some of them! Very exciting! In nine minutes i've got so much of useful info... that i need to listen this again )))
Love it!!!!
I'm working right now on my final project for my physics university degree and it's about wavefolders and state variable filters. I can't be more lucky with your videos.
Thank you a lot for sharing your work.
Nice one! It would be cool to see a Serge DUSG breakdown from you
I'll do one as soon as I understand it myself. :)
It would be great to have some insight on how to simulate an OTA with a traditional op-amp, even if only the "linear" part.
Alas, it's not possible at all -- the main thing about the OTA that makes it so useful it that it has that extra input pin that controls the gain. The closest thing I could think of is the chip used in the Polyvox VCF that uses a special weird "programmable" op amp with a pin that lets you set the filter bandwidth.
hey I'm really curious about Yamaha's implementation of filters with their ICs...is there any special sauce? or is it more standard like other ICs?
I've wondered that myself. I really don't know enough about their chips to say. There's not a lot of info on them.
E então? Obrigado.
aa Preciso de um e ou , baixa potência, três circuitos independentes cada um SÓ com seus 2 ou mais amplificadores operacionais, em Classe D, com fonte SIMÉTRICA comum, circuitos quase iguais e SÓ sintonizados na entrada de áudio. Veja que não é SÓ Pré ou SÓ Equalizador. É bem simples, mas é e sem potenciômetros nas tonalidades. Por favor. Muito obrigado.
Então?
