This is a demo of the Monotonic Labs Type N37 Synthesizer.
The Type N-37 Synthesizer is a unique device, combining a four-step sequencer with the Type-U73 voltage-controlled oscillator (VCO).
Details at the Monotonic Labs site.
That's a really nice synth, I like the idea of the mini step sequencer.
