What ist Shruthi ?

The Schruthi is a hybrid digital/analog monosynth. Its hardware design is deceptively simple, but the sonic range is wide: sometimes grungily digital, fat and funky, sometimes like a video game or wide and warm; but mote often thannot, truly original.

And the story goes on. I forgot, it is a wonderfull lead and bass synth.

And because we lost in the Schruthi-Versum we realize a 30 jears old dream.

>>building a  ladder filter , and the Shruthi

is the perfect basis for this.

So we present  after hard work the  LADDER FILTER for Shruthi.

PCB made with Target 3001 from ibfriederich.com

Special thanks to Mr. Schneider for his fantastic telephon support.
