# Qu-Bit Nautilus Cheat Sheet
## Overview
- **Nautilus** is a multi-tap, complex delay processor with 8 configurable delay lines and extensive modulation capabilities.
- Inspired by underwater acoustics and sonar systems, it provides stereo IO, deep feedback/routing, pitch/delay manipulation, and unique topography-based CV/gate out.

## Panel Controls Quick Reference
### Knobs (All CV-controllable, range: -5V to +5V unless noted)
| Knob | Function | CV Input (range) |
|--------------|----------------------------------------------------------------------|--------------------------|
| Mix | Dry/Wet blend | -5V to +5V |
| Resolution | Delay clock div/mult from 512nd note to 2 bars | -5V to +5V |
| Feedback | Delay feedback amount, has assignable attenuverter | -5V to +5V |
| Sensors | Number of active delay lines (1–4 per channel, up to 8 total) | -5V to +5V |
| Dispersal | Spacing between delay taps (attenuverter assignable) | -5V to +5V |
| Chroma | Internal FX type selector (see below) | -5V to +5V |
| Depth | Amount of effect applied by Chroma | -5V to +5V |
| Reversal | How many (and which) delay lines are reversed | -5V to +5V |
### Buttons
| Button | Function |
|-------------|-----------------------------------------------------------------------|
| Freeze | Locks current delay buffer (max 10s), acts as beat repeat |
| Purge | Clears/bypasses all delay lines |
| Tap | Sets internal clock with tap tempo; hold for secondary functions |
| Delay Mode | Select: Fade, Doppler, Shimmer, De-Shimmer (pitch up/down) |
| Feedback Mode | Select: Normal, Ping Pong, Cascade, Adrift |
#### Tap + (Secondary Functions)
- **Tap + Purge**: Factory reset (input level, delay mode, feedback mode to default)
- **Tap + Turn Dispersal Attenuverter**: Set input gain (-12dB to +12dB, L Kelp LEDs display)
### Chroma FX Types (Color-coded by LED)
- **Blue:** Lowpass Filter (“Oceanic Absorption”)
- **Green:** Highpass Filter (“White Water”)
- **Purple:** Bitcrusher/SR Reduction (“Refraction Interference”)
- **Orange:** Saturation (“Pulse Amplification”)
- **Cyan:** Wavefolder (“Receptor Malfunction”)
- **Red:** Heavy Distortion (“SOS”)

## Additional Features
- **USB (Type A)**: For config, updates, and power (500mA max, consider PSU!).
- Used with "Narwhal" web configurator [here](https://nautilus.qubitelectronix.com/nautilus/configure).
- Place **options.json** on USB drive and insert to configure.
- **Assignable Attenuverters**: Attenuverter knobs can assign to any CV input.
- **Sonar Output Config**: Options: stepped CV, master/variable clock, ping generator.
---
## Delay Modes
- **Fade**: Smooth time changes
- **Doppler**: Classic delay-time pitch bends
- **Shimmer**: Pitch up (default: +12 semitones, configurable)
- **De-Shimmer**: Pitch down (default: –12 semitones, configurable)
## Feedback Modes
- **Normal**: Stereo matches input
- **Ping Pong**: Stereo bouncing
- **Cascade**: Serial chaining of delay lines (ultra long delays)
- **Adrift**: Cascade with alternating L/R routing
---
## Quick Usage Tips
- **Freeze** creates beat repeats; **change Resolution** for rhythms.
- **Dispersal + Sensors** alter rhythmic complexity and stereo spreads.
- **Chroma + Depth** create everything from filtering to heavy distortion on repeats.
- **Reversal** gives reverse delays (per-line, not simple FX).
- **Sonar out** can modulate other modules or self-patch for wild effects.

## Reference
- **Power**: +12V: 151mA, –12V: 6mA
- **Size**: 14HP, 22mm deep
- **Internal/external clock sync**: Internal (tap), External (clock in)
- **Audio**: True stereo, 48kHz/24-bit, Burr-Brown converters
