Xhun Audio - Little One

"Xhun Audio is proud to present LittleOne, a faithful emulation of a new classic: the Moog Little Phatty analog synthesizer.

To produce the same rich and warm sound of the original hardware, LittleOne emulates every single component of the Little Phatty (oscillators, filter, envelopes, LFO ...), preserving the original frequency responses and frequency ranges.

The result is an analog-sounding instrument - all in the digital domain.

But it's not over.
In addition to the Little Phatty synthesizer emulation, LittleOne encloses a full rack with a 16-step MIDI sequencer, a 16-step trancegate effect and two master effects slots. Go to 'Specs' section for more details."
