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:
