The Shruthi-1 is a DIY single-voice synthesizer, designed for ease of construction and use. Using a modular design, the digital control board generates an audio waveform which is then processed by one of many possible analog filter boards. This level of customization allows you to build the synthesizer you've always wanted.

Alternatively, the Shruthi can also process external audio - allowing you to apply any of the filterboards to your microphone, keyboard synthesizer, or any other audio source.

As an open-source project, extensive documentation is available for the entire Shruthi system.

A fully through-hole design makes this an easy assembly for all levels of DIY experience.
