Shruti-1

Description

The Shruti-1 is the first project from Mutable instruments. It employed the same basic hardware configuration as the most common Arduino boards (ATMega328p clocked at 16 MHz), and a classic CEM3379 VCF/VCA chip for the analog section. About 80 units of this minimalistic hybrid MIDI synth have been built (50 from kits, 30 from bare boards).

The Shruti-1 is discontinued, and has been reincarnated into the more powerful, flexible Shruthi-1.

A SoundCloud group has been created to gather tracks/sound clips made with the Shruti-1 (from the simplest demo sound to commercial tracks).

If you are curious about the Shruti-1 feature set, have a look at the user manual.
