Here is my attempt to create my own version of Shruthi-1.
There are various Duran Duran tribute bands, songs, etc., so why not a DD tribute synth
Some technical info:
Oscillator 1 uses CEM3340.
Oscillator 2 is digital and is based on Shruthi-1 source code.
Analog filter is SSM2164 / 4-Pole Mission design.
If anyone wants to see RIO-1 in action, below is a small demo:
Could we see under the hood
Awesome piece of work there!
Board on the left is a 4-PM filter & vca, on the right is oscillator 1 (CEM3340, “ultra saw”, ring mod) and a mixer. I used both types of components together - through-hole & SMD
Digital part was made on one big universal board:
Congratulations, Shruthi-1 lives!
That’s awesome. So on the digital board is that a stm32 f405 on that little green breakout board?
