MIDI control for the Red Panda Particle 2 granular delay — 8 delay and pitch modes, freeze, grain density, pitch quantization and 127 presets.
Nitelite gives the Particle 2 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
BLEND
CC 12
Adjusts the wet/dry mix, from 100% dry to 100% wet. The dry signal stays at unity gain until 12:00, so there will be a slight volume boost when the wet and dry signal are combined
CHOP
CC 13
Grain size. Determines how often the playback head jumps and the size of each slice played back. Short grain sizes create noisy textures or "broken" delay sounds; long grain sizes will randomly slice the signal. On the hardware the CHOP knob also sets the freeze threshold above 12:00 — here that is the separate Freeze Threshold control
FDBK
CC 15
Adjusts audio feedback (repeats)
FREEZE THRESH
CC 14
Amplitude threshold for freezing the current delay buffer. NOT a plain sweep: 0 = Off, 1-126 = threshold, 127 = On (continuously loops). The input signal plays through when its level exceeds the threshold; when it drops below, the pedal reads from the delay buffer instead
FDBK TONE
CC 27
Feedback lowpass filter cutoff frequency — controls the brightness of the repeats
GRAIN PAN
CC 32
Fixed pan position for grains. NOT a plain sweep: 0-63 pan left, 64 center, 65-127 pan right. The random stereo spread is added to this fixed pan position
GRAIN SPREAD
CC 33
Random pan range — pans each grain to a random position within the stereo field. The CHOP control adjusts how smoothly the sound moves

Per-Mode Parameters
Pitch + Dens
Control
MIDI CC
Description
PITCH
CC 18
Base playback pitch of each grain, +/- 1 octave (64 = unison). Can be quantized to different intervals with the Pitch Quantization setting
DENSITY
CC 21
Grain density (interonset time). Lower settings break the incoming audio down into blips; at higher settings there will be multiple overlapping grains
Pitch + LFO
Control
MIDI CC
Description
PITCH RANGE
CC 18
Range of pitch shift, from one octave down to one octave up. Within that range the pitch ramps at the LFO rate
LFO RATE
CC 25
Rate that the pitch sweeps from unison to the Pitch setting. Since the pitch changes once per grain, CHOP changes the result from smooth pitch sweeps to stepped arpeggios
Pitch + Dtune
Control
MIDI CC
Description
PITCH
CC 18
Base playback pitch of each grain, +/- 1 octave (64 = unison)
DETUNE
CC 19
Adds random detuning around the set base pitch. Lower settings introduce slight detuning similar to a dual-oscillator synth; as it is increased, the amount of detuning and number of simultaneous grains increase, creating pitch clouds
Delay + Rnd
Control
MIDI CC
Description
MAX DELAY
CC 16
Maximum delay time, 0-2500 ms, with the same scaling as the DELAY/PITCH knob
RANDOM
CC 17
Delay randomization range, relative to the maximum delay time. No randomization gives a normal delay; at maximum the playback head randomly jumps between 0 and the maximum delay time
Delay + Pitch
Control
MIDI CC
Description
DELAY
CC 16
Delay time, 0-2500 ms
PITCH RND
CC 20
Amount of random pitch jump for each grain, added to the base pitch shift. Random pitch jumps add an unstable shift between unison and another pitch
Delay + Rev
Control
MIDI CC
Description
DELAY
CC 16
Delay time, 0-2500 ms
DIRECTION
CC 22
Probability of each grain playing forward or reverse. NOT a plain sweep: 0 = full reverse, 1-126 = probability, 127 = fully forward (the default). At 12:00 grains are equally likely to play forward and reverse
Delay + LFO
Control
MIDI CC
Description
DELAY RANGE
CC 16
Length of the audio buffer (maximum delay time) that the LFO sweeps through, 0-2500 ms
STRETCH
CC 25
Stretch/compress ratio (LFO speed). At noon the sweep is off, giving a normal delay sound. Below noon the sweep gets progressively slower for time stretching and buffer skip; above noon it gets faster for time compression and stutter
Delay + Dens
Control
MIDI CC
Description
DELAY
CC 16
Delay time, 0-2500 ms
DENSITY
CC 21
Grain density (interonset time). Lower settings break the incoming audio down into blips; when CHOP and Density are both high the audio will perfectly overlap
Footswitches
TAP — bypass on CC 89, hold on CC 80
ON — bypass on CC 81
Special MIDI Functions
Tap Tempo — CC 89
Expression — CC 4
Receive MIDI Clock — CC 110. Global setting — when on, the Particle 2 syncs its note divisions to incoming MIDI timing clock. On by default on the hardware; remembered when power is turned off
Trails — CC 111. When on, the effect decays naturally after the pedal is switched to bypass. Off by default because some settings will freeze the sound indefinitely. Saved in presets and remembered when power is off
Expert Mode — CC 119. When on, the MODE switch reassigns the DELAY/PITCH and PARAM controls without resetting any parameters, so parameters from different modes can be combined. The bypass LED turns white. Turning expert mode off resets parameters based on the current MODE
Freeze — CC 80. Freezes the current delay buffer (0-63 off, 64-127 on) — the MIDI equivalent of holding the TAP/FREEZE footswitch. Behavior depends on the Freeze Mode setting
Delay Note Division — CC 106. Note division for the delay time under tap tempo or MIDI clock. Uses the shared note-division table: 0 = off, 10 = whole, 13 = half, 16 = quarter, 19 = eighth, 22 = 16th, 25 = 32nd, 28 = 64th, 31 = 128th (dotted values sit one below each basic value, triplets one above)
Density Note Division — CC 107. Note division for grain density under tap tempo or MIDI clock. Same 0-31 table as the delay note division; 0 disables tempo sync for this parameter
Chop Note Division — CC 108. Note division for grain size (chop) under tap tempo or MIDI clock. Same 0-31 table; 0 disables tempo sync for this parameter
LFO Note Division — CC 109. Note division for the LFO rate under tap tempo or MIDI clock. Same 0-31 table; 0 disables tempo sync for this parameter
Hardware Presets
The Particle 2 has 127 hardware preset slots. Nitelite can save your current settings to a slot and recall slots via MIDI program change.
