| Clock Mode Button | button | — | Swaps between Free Clock Mode (blue LED, default) and Quantized Clock Mode (gold LED). Free mode: smooth rate control. Quantized: syncs to internal (default 120BPM) or external clock.713 |
| Distribute | knob | — | Rhythm event generator. In Free Clock Mode: increases chance and intensity of random rhythmic variations in grain rate, up to 100% random at maximum. In Quantized Clock Mode: increases chance of quantized rhythmic variations (rests, ratchets, patterns) while staying clock-synced.713 |
| Drift | knob | — | Picks random positions within the audio buffer for grain generation, relative to the Zone position. In Free Clock Mode: randomizes across the whole buffer. In Quantized Clock Mode: jumps to quantized buffer positions (quarter notes, whole notes, etc.).713 |
| Freeze Button | button | — | Freezes grains in place; all grain controls halted. Audio buffer refills with new audio every buffer length when active. Right Dune LED turns white when active.713 |
| Gen Button | button | — | Manually triggers a grain independent of the clock rate. Multiple rapid presses overlap events for syncopated granular rhythms.713 |
| Gen Mode Button | button | — | Cycles between three grain generation modes: Erode (blue, default), Shear (green), Chisel (gold).713 |
| Gust | knob | — | End-of-chain effect. Center = no effect. CCW of center increases feedback amount. CW of center increases reverb amount. Reverb size, dampening, and width configurable via Narwhal.713Zones- Feedback -100–0%Increases internal feedback amount as knob moves left from center.713
- Reverb 0–100%Increases reverb amount as knob moves right from center.713
|
| Lock Button | button | — | Locks the current audio buffer in place. While locked, Zone becomes a buffer scrub control. Left Dune LED turns white when active.713 |
| Mix | knob | — | Blends between dry and wet signal. Fully CCW = dry only; fully CW = wet only. Default mix curve is constant power pan curve. Mix curve configurable via Narwhal.713 |
| Rate | knob | ≥15BPM | Controls grain trigger frequency. In Free Clock Mode: smooth range from slow to audio rate (15BPM to audio rate). In Quantized Clock Mode: acts as a clock div/mult selector.713 |
| Size | knob | 20ms – 4000ms | Adjusts grain length (20ms to 4s) and playback direction. Shortest grain at center. CW from center = forward playback. CCW from center = reverse playback. Reverse grains flip the Window shape.713Zones- Reverse -100–0%CCW from center plays grains in reverse, increasing reverse grain length toward maximum. Reverse grains flip the Window shape.713
- Forward 0–100%CW from center plays grains forward, increasing grain length up to 4s at maximum.713
|
| Sky Mode Button | button | — | Cycles between 4 quantization modes: Dawn (blue, Major Scale), Day (green, Minor Scale), Dusk (gold, Chromatic Scale), Twilight (purple, Unquantized). Each mode affects Structure, Speed, and rhythmic components. Scale per mode configurable via Narwhal.713 |
| Speed | knob | -2octave – 2octave | Adjusts vari-speed pitch of each grain. Range: -2 to +2 octaves. Original pitch at center. Acts as offset for Structure's random pitch modulation. Quantized to Sky Mode scale.713 |
| Structure | knob | — | Randomly manipulates grain pitch. Adds and removes pitch modulation types across the knob travel: octave shifts, semitone shifts, and melodic events (arpeggios/trills) at different knob positions. Quantized to the selected Sky Mode scale.713 |
| Tap Tempo Button | button | — | 713 |
| Whirl | knob | — | Controls stereo spatialization of grains. Turning clockwise causes grains to deviate from their original stereo position up to fully random positioning. Can optionally include random reverse grain playback via Narwhal.713 |
| Window | knob | — | Controls the amplitude envelope shape of each grain. Crossfades between 5 shapes: Hamming, Up Ramp, Triangle, Exp. Down Ramp, Square (left to right). Each shape corresponds to a unique LED color.713ZonesHamming Up Ramp Triangle Exp. Down Ramp Square - Hamming -100–-60%713
- Up Ramp -60–-20%713
- Triangle -20–20%713
- Exp. Down Ramp 20–60%713
- Square 60–100%713
|
| Zone | knob | — | Sets the audio buffer position for grain generation. Fully CCW = real-time audio. Turning CW accesses progressively older buffer contents. When Lock is active, becomes a buffer scrub control. Also acts as offset for Drift.713 |
