Strymon NightSky — MIDI Editor & CC Reference
Control the Strymon NightSky from your browser — MIDI control reference, interactive editor, and AI-generated presets. Free, no install.
Explore the NightSky controls in your browser and connect compatible MIDI hardware to send settings to your pedal. The reference below shows the controls mapped in Nitelite; available functions depend on the pedal and firmware. The default MIDI channel in Nitelite is 1. Browser MIDI control works in Chrome, Edge, Opera, or Brave — no install required.
Knobs
| Control | MIDI CC | Description |
|---|---|---|
| LENGTH | CC 18 | Reverb decay time from less than one second to nearly infinite sustain |
| SIZE/PITCH | CC 20 | Reverb core size — also controls pitch when audio is in the buffer |
| REVERB | CC 11 | Output level of the reverberated signal |
| DRY | CC 12 | Output level of the dry signal (min=silent, noon=unity, max=+3dB boost) |
| SPEED | CC 13 | Modulation rate from 0.06Hz (16s sweep) to 12Hz (0.08s sweep) |
| DEPTH | CC 15 | Modulation amount (off at minimum; for envelope shape, off at 12 o'clock) |
| LOW CUT | CC 22 | Removes low end from output and regenerating core as knob is turned clockwise |
| HIGH CUT | CC 23 | Removes high frequencies from reverb — behavior set by Filter mode |
| INTERVAL | CC 26 | Shimmer pitch interval from -octave to +octave (12=detune, 13=+detune) |
| SHIMMER | CC 29 | Amount of shimmer effect (off at minimum) |
| PRE-DELAY | CC 17 | Time between dry signal and reverb onset |
| GLIMMER GAIN | CC 31 | Sensitivity of the glimmer effect to the input signal |
| DRIVE LEVEL | CC 34 | Sensitivity of the drive effect |
| LOWPASS Q | CC 25 | Filter Q / resonance sharpness when Filter is set to lowpass |
| SEQ GLIDE | CC 58 | Portamento smoothing between sequencer steps |
| MORPH SPEED | CC 37 | Time to sweep between current and morph settings |

Special MIDI Functions
- Expression — CC 100
- Freeze — CC 35. Freezes the reverb tail — holds the current reverb indefinitely while bypassing new input to the reverb core.
- Morph — CC 36. Engages Morph — sweeps from the current preset settings to the saved Morph destination at the rate set by MORPH SPEED.
- Sequence Mode — CC 41. Switches between Preset mode (0) and Sequence mode (1–127). In Sequence mode the 8-step sequencer drives SIZE/PITCH.
- Sequencer Step 1 On/Off — CC 42. Enables or disables step 1 of the 8-step sequencer.
- Sequencer Step 2 On/Off — CC 43. Enables or disables step 2 of the 8-step sequencer.
- Sequencer Step 3 On/Off — CC 44. Enables or disables step 3 of the 8-step sequencer.
- Sequencer Step 4 On/Off — CC 45. Enables or disables step 4 of the 8-step sequencer.
- Sequencer Step 5 On/Off — CC 46. Enables or disables step 5 of the 8-step sequencer.
- Sequencer Step 6 On/Off — CC 47. Enables or disables step 6 of the 8-step sequencer.
- Sequencer Step 7 On/Off — CC 48. Enables or disables step 7 of the 8-step sequencer.
- Sequencer Step 8 On/Off — CC 49. Enables or disables step 8 of the 8-step sequencer.
- MIDI Expression On/Off — CC 60. Enables MIDI expression pedal control via CC 100. When on, an expression pedal connected via MIDI can sweep parameters in real time.
- MIDI Clock On/Off — CC 63. Enables MIDI clock sync. When on, NightSky syncs its modulation and sequencer timing to incoming MIDI clock.
- Bank Select — CC 0. Selects the MIDI preset bank. Bank 0 = presets 0–127, Bank 1 = 128–255, Bank 2 = 256–299. Send before a Program Change to access banks 1 and 2.
- Sequencer Step 1 Size — CC 50. SIZE/PITCH value for sequencer step 1 — sets the pitch interval played when this step is active.
- Sequencer Step 2 Size — CC 51. SIZE/PITCH value for sequencer step 2.
- Sequencer Step 3 Size — CC 52. SIZE/PITCH value for sequencer step 3.
- Sequencer Step 4 Size — CC 53. SIZE/PITCH value for sequencer step 4.
- Sequencer Step 5 Size — CC 54. SIZE/PITCH value for sequencer step 5.
- Sequencer Step 6 Size — CC 55. SIZE/PITCH value for sequencer step 6.
- Sequencer Step 7 Size — CC 56. SIZE/PITCH value for sequencer step 7.
- Sequencer Step 8 Size — CC 57. SIZE/PITCH value for sequencer step 8.
- Sequence Tap — CC 93. Taps the sequencer tempo — send any value to advance the tap tempo for the sequencer rate.
Hardware Presets
NightSky has 300 hardware preset slots, recalled using MIDI Program Change. Saving requires an action on the pedal; follow the hardware preset manager instructions.
