Chase Bliss Wombtone MKII — MIDI Editor & CC Reference

Control the Chase Bliss Wombtone MKII from your browser — MIDI control reference, interactive editor, and AI-generated presets. Free, no install.

Explore the Wombtone MKII 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 6. Browser MIDI control works in Chrome, Edge, Opera, or Brave — no install required.

Knobs

Control	MIDI CC	Description
FEED	CC 14	Feedback/resonance intensity. CW = syrupy/intense, CCW = subtle. Interactive with stage count. Controls ramp speed when ramping engaged.
VOLUME	CC 15	Effect level with internal voltage doubler and boost circuit for massive headroom.
MIX	CC 16	Dry to pure phase vibrato. Middle = classic phase chorusing.
RATE	CC 17	Phase effect rate. MKII allows very slow rates. Overridden by tap tempo.
DEPTH	CC 18	Phase range/width. Clockwise for wide frequency spectrum sweep.
FORM	CC 19	Waveform asymmetry. CCW = quick up/slow down, CW = slow up/quick down, noon = symmetric.

Switches

Switch	MIDI CC	Positions
WAVE L	CC 21	SINE / TRI / SQR
DIV/STG	CC 21	1/2 / 1/4 / 1/8
WAVE R	CC 21	SQR / TRI / SINE

DIP Switches — RAMP/EXP

Control	MIDI CC	Description
VOLUME	CC 61	Enable ramping/expression control for VOLUME knob
MIX	CC 62	Enable ramping/expression control for MIX knob
RATE	CC 63	Enable ramping/expression control for RATE knob
DEPTH	CC 64	Enable ramping/expression control for DEPTH knob
FORM	CC 65	Enable ramping/expression control for FORM knob
BOUNCE	CC 66	Bounce: parameters modulate back and forth. Off: ramp and hold.
STAGES	CC 67	Enables stage selection on tap division toggle: 2, 4, or 6 phase stages
MoToByp	CC 68	Momentary-to-bypass: pedal only active while bypass stomp is held

DIP Switches — DIRECTION

Control	MIDI CC	Description
VOLUME	CC 71	VOLUME ramp direction: rise (CW) or fall (CCW)
MIX	CC 72	MIX ramp direction: rise (CW) or fall (CCW)
RATE	CC 73	RATE ramp direction: rise (CW) or fall (CCW)
DEPTH	CC 74	DEPTH ramp direction: rise (CW) or fall (CCW)
FORM	CC 75	FORM ramp direction: rise (CW) or fall (CCW)
TAP CTRL	CC 76	R = tap sets ramp rate, P = tap sets Rate
TAP DIV	CC 77	Enables alternate tap division bank (3/6/8 instead of 1/2/4)
SWEEP	CC 78	Sweep direction for ramp/expression. T = knob to max, B = knob to min.

Footswitches

TAP — CC 93
BYPASS — CC 102

Special MIDI Functions

Tap Tempo — CC 93
Expression — CC 100
MIDI Clock Ignore — CC 51. When enabled, the pedal ignores incoming MIDI clock and uses its own internal rate. When disabled, RATE syncs to the MIDI clock tempo.
Ramp Speed — CC 20. Sets the ramp speed directly via MIDI — how fast the controlled parameter travels from one end of its range to the other when ramping is engaged.
MIDI Note Divisions — CC 21. Sets the tap/MIDI clock division: 0 = whole note, 1 = half note, 2 = quarter note triplet, 3 = quarter note, 4 = eighth note, 5 = sixteenth note.

Hardware Presets

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