Chase Bliss Thermae — MIDI Editor & CC Reference

Control the Chase Bliss Thermae from your browser — full MIDI CC reference for 9 parameters, interactive editor, and AI-generated presets. Free, no install.

Nitelite gives the Thermae 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 2). Works free in Chrome, Edge, Opera, or Brave — no install required.

Knobs

Control	MIDI CC	Description
MIX	CC 14	Clean/delayed signal balance. Controls ramp speed when ramping is engaged.
LPF	CC 15	Resonant low-pass filter. Clockwise = bright, counter-clockwise = mellow.
REGEN	CC 16	Echo regeneration/feedback. Higher = more smeary, tape-saturated blur. Can self-oscillate.
GLIDE	CC 17	Portamento between sequence steps. Min = immediate shifts, higher = long slides.
INT 1	CC 18	Interval 1 / Speed. Pitch shift amount for step 1. Noon = bypass step. With MODULATION dip: modulation speed.
INT 2	CC 19	Interval 2 / Depth. Pitch shift amount for step 2 (relative to step 1). Noon = bypass step. With MODULATION dip: modulation depth.

Alt / Secondary Knob Functions

Control	MIDI CC	Description
HOLD	CC 24	Simulates hold function: 127 = runaway oscillation, 0 = resume regen position
SLOW/TAP	CC 25	Sequence mode: slowdown. Step mode: set tap tempo. 127 = engage, 0 = disengage.

Switches

Switch	MIDI CC	Positions
NOTE DIV	CC 21	1/4 / 1/8D / 1/8
NOTE DIV	CC 22	1/4 / 1/8D / 1/8
NOTE DIV	CC 23	1/4 / 1/8D / 1/8

DIP Switches — RAMP/EXP

Control	MIDI CC	Description
REGEN	CC 61	Enable ramping/expression control for REGEN knob
INT 1	CC 62	Enable ramping/expression control for INT 1 (Speed) knob
INT 2	CC 63	Enable ramping/expression control for INT 2 (Depth) knob
GLIDE	CC 64	Enable ramping/expression control for GLIDE knob
LPF	CC 65	Enable ramping/expression control for LPF knob
BOUNCE	CC 66	Bounce mode: parameters modulate back and forth instead of ramp-and-hold
SWEEP	CC 67	Sweep direction. Top: knob = max of range. Bottom: knob = min of range.
POLARITY	CC 68	Ramp polarity. Forward: normal. Reverse: inverted.

DIP Switches — CUSTOMIZE

Control	MIDI CC	Description
STEP	CC 71	Step Mode - Pauses internal sequencer, advance manually with left footswitch
MODULATION	CC 72	Changes INT 1/2 knobs to Speed/Depth, toggles to waveform shape/randomness controls
MoToByp	CC 73	Momentary-to-bypass: pedal only active while bypass stomp is held down
TRAILS	CC 74	Echoes fade out naturally after bypass instead of cutting off. Switches to buffered bypass.
TAP CTRL	CC 75	R = ramp (tap sets ramp rate), P = parameter (tap sets RPM). Needs Bounce on for continuous modulation.
TAP DIV	CC 76	Tap division bank selection. Enables alternate note divisions for tap tempo.
UNUSED	CC 77	Reserved / unused DIP switch position
UNUSED	CC 78	Reserved / unused DIP switch position

Footswitches

TAP/STEP — bypass on CC 93
BYPASS — bypass on CC 102

Special MIDI Functions

Tap Tempo — CC 93
Expression — CC 100
MIDI Clock — CC 51. Controls whether the Thermae listens to incoming MIDI Clock (Beat Clock) messages. On = listen for MIDI Clock, Off = ignore MIDI Clock.
Ramp Speed — CC 20. Controls the speed of parameter ramping when ramping is engaged. Lower values = slower ramp, higher values = faster ramp.

Hardware Presets

The Thermae has 122 hardware preset slots. Nitelite can save your current settings to a slot and recall slots via MIDI program change.
