Strymon BigSky — MIDI Editor & CC Reference

Control the Strymon BigSky from your browser — MIDI control reference, interactive editor, and AI-generated presets. Free, no install.

Explore the BigSky 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.

Special MIDI Functions

Expression — CC 100
Persist (Trails) — CC 22. When on, reverb trails continue to decay after bypassing the pedal. Requires Buffered Bypass mode.
MIDI Clock — CC 71. Enables MIDI Clock input so tempo-synced reverb machines (e.g. Magneto) lock to an external clock source.
Expression Enable — CC 60. Enables or disables the expression pedal input. When off, the EXP jack is ignored.
Value Encoder — CC 20. Controls the VALUE encoder. Send 0 to decrement, 1 to increment the currently selected parameter value.
Boost — CC 23. Analog boost/cut, roughly -3dB to +3dB. The midpoint (30) is unity gain; lower values cut, higher values boost.
MIDI Patch Bank — CC 0. Selects the active MIDI patch bank. Bank 0 = presets 00A–42B, Bank 1 = 42C–85A, Bank 2 = 85B–99C. Send before a Program Change to access all 300 presets.
Remote TAP — CC 93. Sends a tap tempo pulse to BigSky. Any CC value triggers the tap. Connect to an external tap footswitch or MIDI controller.

Hardware Presets

BigSky has 300 hardware preset slots, recalled using MIDI Program Change. Saving requires an action on the pedal; follow the hardware preset manager instructions.
