Nautilus 1 is now a free device. Check out Nautilus 2 in the shop!
The Nautilus Bass Synthesizer is a mono/poly subtractive synthesizer.
3 oscillators: Saw, Square, Sine.
Each oscillator is followed by their own waveshaper, with each waveshaper having their own Pre/Post setting for the filter routing. That allows for the filter section to be routed before the waveshaper on one oscillator, but after the waveshaper on another. Nautilus wants to be tweaked!
