Page 3: Foreword
What if we could model this behavior digitally, and apply it to musical purposes in the hardware domain? That is the ques- tion which inspired the Nautilus. It was not an easy question to answer, and we had to make some subjective choices along the way (what does... -
Page 4: Description
Nautilus and its surroundings. Though Nautilus is a delay effect at heart, it is also a CV/Gate generator. The Sonar Output creates either a unique Gate signal, or a unique CV signal algorithmically created from Nautilus’s findings. Drive other parts of your patch with pings from the delay network, or use the generated topography as a modulation source. -

Recommended Listening Robert Fripp (1979). Frippertronics. Robert Fripp is a British musician and member of the progressive rock group King Crimson. A guitar virtu- oso, Fripp developed a new performance method using tape delay machines to loop and layer musical phrases to create ever evolving asymmetrical patterns. -

Page 8: Functions
Tap Tempo button. Simply tap along to whatever tempo you desire, and Nautilus will ad- just its internal clock to your taps. Nautilus requires at least 2 taps to determine a clock rate. The default internal clock rate at boot up is always 120bpm. -
Page 9: Resolution
CV input signal is fully attenuated. When the knob is fully CCW, the CV input is fully inverted. Range: -5V to +5V Did You Know? Nautilus’s attenuverters are assignable to any CV input on the module, and can even become their own functions! Learn how to configure the attenuverters by reading the section of the manual. -
Page 10: Sensors
When the knob is fully CW, 4 delay lines per channel are available (8 total). As you turn up the knob from CCW to CW, you will hear Nautilus add the delay lines to its signal path. The lines will be fairly tight initially, firing in quick succession each hit. The Kelp LEDs will flash white each time Sensors are added or removed from the delay network. -
Page 11: Reversal
3R 4R Reversal CV input range: -5V to +5V Note : Due to the nature of the internal algorithms driving the Nautilus feedback network, reversed delay lines will repeat 1 time before pitch shifting in Shimmer and De-Shimmer modes. 8. Chroma... -
Page 12: Lowpass Filter
Functions: The Knobs 8A. Oceanic Absorption A 4-pole lowpass filter for dampening the delay signal. When Depth is fully CCW, no filtering is occurring. When Depth is fully CW, maximum filtering is occurring. Indicated by a blue Kelp base. 8B. White Water A 4-pole highpass filter applied to the delay signal. -
Page 13: Depth
Functions: The Knobs 9. Depth Depth is the complementary knob to Chroma, and controls the amount of the chosen Chroma effect applied to the feedback path. When Depth is fully CCW, the Chroma effect is off, and will not be applied to the buffer. When Depth is fully CW, the maximum amount of the effect is applied to the active delay line. -
Page 14: Delay Modes
LED graphic above the button. Doppler The Doppler delay mode is the vari-speed delay time variant of Nautilus, giving you the classic pitch shift sound when changing delay times. This delay mode is indicated by a green LED graphic above the button. -
Page 15: Feedback Modes
= audio’s ste- reo position How to Ping Pong a Mono Signal: Since Nautilus has an analog normalization at the inputs, the left channel input signal is copied to the right channel when no cable is present in the right channel input. There are a couple options to use this mode with a mono signal: 1. -
Page 16: Cascade
2R boxes in the above graphics connect from both boxes to their respective signal output lines next to them. Here’s a fun patch to show this interaction: Patch a simple, slow arpeggio into Nautilus. Set delay mode to Shimmer, and set Feedback mode to either Cascade or Adrift. Resolution and Feed- back should be at 9 o’clock. -
Page 17: Purge
By analyzing overlapping delay pings and delay time phases, Nautilus creates an ever evolving stepped CV sequence. Use Sonar to self patch Nautilus, or to control other patch points in your rack! A staff favorite is running Sonar out into Surface’s Model input! Did You Know? You can change Sonar’s output using the Nautilus Configurator tool and the USB... -
Page 18: Usb/Configurator
“generate file” button to export an options.json file from the web app. Place the new options.json file onto your USB drive, insert it into Nautilus, and your module will instantly update its internal settings! You’ll know the update is successful when the Kelp base flashes white. - Page 19 Functions: The Buttons Configurator These are the current settings available in the Configurator. More configurable settings will be added in future updates. Setting Default Setting Description Transpose Up Set the amount to transpose in semitones in Shimmer Mode. Choose between 1 to 12 semitones above the input signal. Transpose Down Set the amount to transpose in semitones in De-Shimmer Mode.

Page 20: Patch Examples
Patch Example: Slow Shimmer Delay Nautilus freeze clear sensors depth resolution reversal dispersal clock in chroma feedback sonar left left sensors depth right reversal resolution right Settings Resolution: Dotted Half, or longer Feedback: 10 o’clock Delay Mode: Shimmer Feedback Mode: Ping Pong Turning on Shimmer for the first time can lead to some powerful, and impressionable results. - Page 21 With Nautilus’s Freeze behavior, our sub-nautical delay network can easily take its complex delay rhythms and lock them into a beat repeat/glitch state. And, in Fade mode, Nautilus can create additional delay time rhythms using Resolution and random CV, seamlessly changing between delay frequencies.
- Page 22 For when you are out of modulation sources, why not let Nautilus modulate itself? Using a signal splitter, we can patch the Sonar output to multiple spots on Nautilus. Want to dial back the modulation on some of the patch points? Assign the Attenuverters to wherever you see best. We personally love assigning them to...
- Page 23 All aboard! This fun sound design patch involves fast clocks and faster delays, and really showcases the delay time range on Nautilus! Your clock signal should be pushing audio rate for this patch to work. If you have a Bloom, matching the Rate knob above should do the trick.
