Browser MIDI control works in Chrome, Edge, Opera, or Brave — no install required.

Knobs

Control	MIDI CC	Description
MIX	CC 14	Wet/dry mix. CW = full flange, CCW = clean with tube-like preamp character. Controls ramp speed when ramping is engaged.
ZERO	CC 15	Manual delay time / zero point. Through-zero crossing between 1 and 3 o'clock.
REGEN	CC 16	Flange regeneration/intensity. CW = self-oscillation. CCW = subtle chorus.
RATE	CC 17	Rate of flange modulation. Overridden by tap tempo.
WIDTH	CC 18	Width/depth of flange sweep. CW = deep flange.
SHIFT	CC 19	Modulation wave skew. CCW = fast up/slow down, CW = slow up/fast down, noon = symmetric.

Switches

Switch	MIDI CC	Positions
TAP DIV	CC 21	1/2/4 / 3/6/8 / RAMP
WAVE L	CC 21	SINE / TRI / SQR
WAVE R	CC 21	SQR / TRI / SINE

DIP Switches — CONTROL

Control	MIDI CC	Description
ZERO	CC 61	Enable ramping/expression control for ZERO knob
REGEN	CC 62	Enable ramping/expression control for REGEN knob
RATE	CC 63	Enable ramping/expression control for RATE knob
WIDTH	CC 64	Enable ramping/expression control for WIDTH knob
SHIFT	CC 65	Enable ramping/expression control for SHIFT knob
BOUNCE	CC 66	Ramp mode (off, one-shot) vs Bounce mode (on, back-and-forth)
SWEEP	CC 67	Sweep direction: Top (T, knob=max) or Bottom (B, knob=min)
POLARITY	CC 68	Flange polarity: Positive (musical sweep) or Negative (hollow/intense, cancels at zero). Default = Negative.

DIP Switches — CUSTOMIZE

Control	MIDI CC	Description
MOTBYP	CC 71	Momentary-to-bypass: pedal only active when bypass stomp is pressed
TAP CTRL	CC 72	Tap controls: R = ramp timing, P = rate parameter
TAP DIV	CC 73	Tap division bank: off = 1/2/4, on = 3/6/8. Also selects MIDI note divisions.
RISE (Z)	CC 74	Rise direction for ZERO ramp/expression
RISE (RG)	CC 75	Rise direction for REGEN ramp/expression
RISE (RT)	CC 76	Rise direction for RATE ramp/expression
RISE (W)	CC 77	Rise direction for WIDTH ramp/expression
RISE (S)	CC 78	Rise direction for SHIFT ramp/expression

Footswitches

TAP — CC 102
BYPASS — CC 102

Special MIDI Functions

Tap Tempo — CC 93
Expression — CC 100
MIDI Clock — CC 51. Controls whether the pedal listens to incoming MIDI Clock messages. On = listen (default); Off = ignore.
Ramp — CC 20. Controls ramp amount. Sending 0 is equivalent to the ramp knob fully counter-clockwise; 127 is fully clockwise.
MIDI Note Divisions — CC 21. Sets the tap tempo note division via MIDI. 0 = whole note, 1 = half note, 2 = quarter note triplet, 3 = quarter note, 4 = eighth note, 5 = sixteenth note.

Hardware Presets

SPECTRE has 122 hardware preset slots, recalled using MIDI Program Change. Saving requires an action on the pedal; follow the hardware preset manager instructions.
