The Little Phatty boasts a 100 percent analog signal path, 100 user editable presets and a 37-note keyboard. It is a monophonic synth with two oscillators (the Voyager has three osc). Waveform selector is continuously variable between waveforms (tri, saw, square, pulse) and there is oscillator-sync. The filter is the classic Moog ladder design. Two ADSR envelope generators are available for the volume and the filter. And finally a nice LFO with six waveshapes, four destinations and rate/depth controls helps to get things moving. The 'Master' section of the keyboard has controls for Tuning, +/-2 Octave Transpose, Glide, Pitch/Mod wheels and some data entry controls.
