Accidental Polysynth

Today, i played around a bit with the impressively simple VCO design of the Korg Trident. Analyzing some of its behaviour and adding sync between 2 of them with just one diode, i decided to add a 24db low pass filter also, which is inspired by the AAC Tiracon 6V filter.
By this, i sort of accidentally created a nearly complete and very simple synthesizer voice. Everything is linear controlled, but for a polysynth, i could use a multiplexed exponential converter like Korg did in the 80s.
Adding some analog switches, noise, maybe sub oscillators, this will give a very simple polysynth i think.
I will continue on this and i'm planning to make it an open source/hardware project for everyone interested in it.

You can spend the scheme? Thank you.

@polimorfomusic As soon as the project is re-started and comes to some sort of "complete" state, it will get online. Currently, there are just some fragments which will change a lot, but it can take quite a while to complete it as i have nearly no time at all currently.

Cool!

Good stuff Mik.

I really like your teaching style.

I'd love to build a synth from the ground up.

wow, I hope you do post this as an open source project. Just imagine adding a DAC as another osc. hmmmmm

thanks

looking forward very much to seeing some further development on this project. Thanks Mik.
