Red Panda Radius — MIDI Editor & CC Reference

MIDI control for the Red Panda Radius ring modulator and frequency shifter — carrier frequency, pitch tracking, 8-step modulator and 100 presets.

Nitelite gives the Radius 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
MIX	CC 14	Dry/wet mix. Adjusts the wet/dry blend, from 100% dry to 100% wet.
TRACK	CC 18	Carrier frequency TRACK input pitch (monophonic): -100% to +100%, off at center (64). Center frequency is C4. At +100% the sidebands move up and down harmonically; negative tracking makes the sidebands farther apart at lower pitches.
FREQ	CC 16	Carrier oscillator frequency (0.65 - 4,000 Hz across the three ranges). Increasing the carrier frequency spreads out the upper and lower sidebands; decreasing it moves them towards the input signal.
RING MOD / FREQ SHIFT	CC 15	Adjusts the balance between upper and lower harmonics and adds feedback. Morphs the output from frequency shift down (about 32) through ring modulation (64) to frequency shift up (about 96); below 32 and above 96 adds feedback (FDBK).
RATE	CC 22	Modulation rate — adjusts the LFO speed (0.1 - 55 Hz). With the envelope follower selected, RATE controls the release time. With X- / X+ it controls the speed of the sweep.
AMOUNT	CC 24	Modulation depth — adjusts the range of carrier frequency changes. With X- / X+ it controls the width of the sweep, up to +/-3 octaves around the FREQ setting. Set to maximum to play a step modulator sequence at full scale.
STEP 1	CC 70	Step modulator step 1 level.
STEP 2	CC 71	Step modulator step 2 level.
STEP 3	CC 72	Step modulator step 3 level.
STEP 4	CC 73	Step modulator step 4 level.
STEP 5	CC 74	Step modulator step 5 level.
STEP 6	CC 75	Step modulator step 6 level.
STEP 7	CC 76	Step modulator step 7 level.
STEP 8	CC 77	Step modulator step 8 level.
LAST STEP	CC 78	Step mod last step (1-8) — sets the length of the sequence. Can be assigned to the expression pedal to change sequence length dynamically.

Footswitches

AUX — bypass on CC 80
ON — bypass on CC 88

Special MIDI Functions

Tap Tempo — CC 89
Expression — CC 4
Mod Envelope Trigger — CC 82. Turns modulation envelope triggering on (64-127) or off (0-63). When on, the modulation waveform is retriggered by your playing; the triangle and square LFOs play in one-shot mode. Not available with Random 2 or the envelope follower.
Receive MIDI Clock (global) — CC 110. Turns MIDI clock reception on (64-127) or off (0-63). This is a global setting and is remembered when power is turned off. To disable clock sync for a single preset, set its note division to Off.
ON Footswitch (momentary) — CC 81. Emulates a press of the ON footswitch (64-127 press, 0-63 release). Holding the ON footswitch from bypass for 400 ms or more gives momentary-on behaviour.

Hardware Presets

The Radius has 100 hardware preset slots. Nitelite can save your current settings to a slot and recall slots via MIDI program change.
