Strymon Deco V2 — MIDI Editor & CC Reference

Control the Strymon Deco V2 from your browser — full MIDI CC reference for 13 parameters, interactive editor, and AI-generated presets. Free, no install.

Nitelite gives the Deco V2 a full browser-based control surface: turn every knob, flip every switch, describe the tone you want to the AI Tone Terminal, and save the results — all sent to the pedal live over MIDI (default channel 1). Works free in Chrome, Edge, Opera, or Brave — no install required.

Knobs

Control	MIDI CC	Description
SATURATION	CC 12	Tape drive / preamp gain. Low = subtle harmonic enhancement, high = dynamic compression and overdrive
LAG TIME	CC 18	Delay offset between Reference and Lag Decks. Flange (low) to chorus to slapback to echo (high)
TONE	CC 14	Overall tone of the Tape Saturation, from dark to bright
BLEND	CC 20	Relative mix of Reference Deck and Lag Deck. CCW = more Reference, CW = more Lag, noon = equal
VOLUME	CC 13	Output volume of the Tape Saturation side
WOBBLE	CC 19	Random modulation on the Lag Deck. Low = mild time-varying flange, high = extreme variations
LOW TRIM	CC 15	High-pass filter to reduce low-end rumble. 0 = full bandwidth (default), higher = more bass cut
BOOST/CUT	CC 21	Doubletracker volume trim. 0 = -3dB cut, 64 = unity (noon), 127 = +3dB boost
AUTO-FLANGE TIME	CC 22	Sweep time for the Auto-Flange effect. Low = fast sweep, high = slow sweep

Special MIDI Functions

Tap Tempo — CC 93
Expression — CC 100
Bypass A and B — CC 33. Controls bypass state of both Tape Saturation and Doubletracker simultaneously. Off = both bypassed, On = both active.
MIDI Expression — CC 60. Enables or disables the MIDI Expression feature. When off, the expression pedal/CC 100 has no effect. Default is on.
Auto-Flange — CC 97. Triggers the Auto-Flange effect. While on, Deco produces a studio-style flanging sweep. Turn off to stop the effect.
Bank Select — CC 0. Selects the MIDI patch bank. Bank 0 = presets 0–127, Bank 1 = presets 128–255, Bank 2 = presets 256–299. Send before a Program Change to access presets above 127.
MIDI Clock Tempo Mult/Div — CC 25. When MIDI Clock Sync is enabled, sets the tempo multiplier/divider for the Lag Time. 0=x1/2, 1=x1, 2=x2, 3=x3, 4=x4, 5=x6, 6=x8.
