Dato DUO

The synth-for-two

The Dato DUO

This is the Dato DUO — an instrument for making electronic music together. You don't have to be an experienced musician: we designed the DUO to be enjoyed by kids aged 3 to 99 and up — that includes you!

Two sides play together

DUO synthesizer side


This side is the synthesizer. Generate and sculpt gritty, bold or soft sounds. You play with filters and add effects such as a  bitcrusher and  accent. And add  beats!

DUO sequencer side


Loop eight notes on the sequencer side. Compose a melody using the keyboard — flashy lights indicate which tone is playing. You can  randomize the sequence,  speed up and pitch up and down.

Wonderfully accessible and lots of fun for pros and beginners alike.

DUO connected to other music gear

The DUO grows along with your skill. As you expand your studio, you can connect other instruments like Volcas and Pocket Operators or hook it up to your modular synth. The DUO has MIDI in and out, SYNC in and out and a 3.5mm headphone/line out.

It looks incredible, the concept and execution are fantastic, and its potential as a tool for teaching basic synthesis to young children is huge
