Soundmachines NS1 Nanosynth Mini Modular Synthesizer and NS1 Exmperimenters Kit

"The NS1nanosynth synthesizer is an handeld 220x85mm analog modular synthesizer coupled with an Arduino Leonardo platform.

Power Supply is 5v/160mA either from the USB micro connector or the classic 5.5mm barrel jack, central positive. If you use use both concurrently, power will be drawn from the barrel jack.

Feeding the NS1 with more than a regulated 5V will result in immediately destruction of most part of the product (i.e. holy smokes + swears).

On board the synth, +12 and -12 voltages, necessary for the oscillator and the filter, are generated through a DC/DC module.

All CV control signals are 0-5V unipolar. Oscillator waveforms outputs are equally 0-5V to be able to use the on board modules to mix cv and audio signals without problems (see the ‘waveshaping’ video for an example of this)."

You can find a demo of the NS1 here.
