Red Panda Raster 2 — MIDI Editor & CC Reference
MIDI control for the Red Panda Raster 2 stereo delay with pitch shifter — shift, feedback, delay time, tone, modulation and the full set of L/R stereo tilt controls.
Explore the Raster 2 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 1. Browser MIDI control works in Chrome, Edge, Opera, or Brave — no install required.
Knobs
| Control | MIDI CC | Description |
|---|---|---|
| SHIFT | CC 16 | Amount of pitch, phase, or frequency shifting. Unison at 12:00. The function and scaling depend on the shift mode switch: transpose (+/-12 semitones), detune (a fourth down to a major third up), or frequency shift (+/-500 Hz). |
| FDBK | CC 20 | Delay line feedback (regeneration). Infinite repeats at approximately 3:00, with greater than unity gain above that. Increasing feedback beyond self-oscillation adds distortion. Use caution — the feedback signal can get very loud. |
| DELAY | CC 18 | Delay time within the selected range. Scaled to allow fine tuning of short delay times for resonant effects; the minimum is 0 ms with no feedback, for pure pitch shifting and amplitude modulation. Fast knob moves jump smoothly; slow moves create drag, time stretching, and glitchy stutter effects. |
| BLEND | CC 14 | Wet/dry blend from 100% dry to 100% wet. The dry signal stays at full volume until approximately 12:00. In Analog + FX Level bypass mode this acts as an effect level control instead. |
| RATE | CC 22 | Modulation LFO frequency, approximately 0.05-10 Hz. Can be synced to tap tempo and MIDI clock. Has no effect when the envelope or inverse envelope waveform is selected. |
| DEPTH | CC 24 | Amount of modulation applied by the LFO or envelope. For envelope modulation it may need to be adjusted based on signal level. With amplitude as the destination it behaves like a tremolo depth control, muting the signal entirely at maximum. |
Alt / Secondary Knob Functions
| Control | MIDI CC | Description |
|---|---|---|
| SHIFT L/R | CC 17 | Shift left/right balance (ALT-SHIFT). Bipolar — 12:00 sets equal shift on both delay lines. Counter-clockwise keeps the left shift constant while reducing, disabling, then inverting the right; clockwise does the reverse. At the extremes the two delays shift in opposite directions. |
| TONE | CC 26 | Tone (ALT-FDBK). Sweeps from very dark repeats (7:00) through analog-style dark (9:00), bright (12:00, default), bright with attack emphasis (1:30), highpass filtered (3:00), to bandpass "telephone" filtered (5:00). Affects the initial delay and all repeats. |
| DELAY L/R | CC 19 | Delay left/right ratio (ALT-DELAY). Bipolar — 12:00 is equal delay times. Counter-clockwise shortens the left delay, clockwise shortens the right. Settings close to 12:00 add a small 0-30 ms offset that makes the repeats shear apart; higher settings snap to ratios of 3:4, 2:3, 1:2, 3:8, 1:3, and 1:4. |
| BLEND L/R | CC 15 | Blend left/right balance (ALT-BLEND). Bipolar — at 12:00 both delay outputs use the same wet/dry blend. Turning counter-clockwise keeps the left output at the BLEND setting and reduces the right; clockwise does the reverse. |
| MOD PHASE L/R | CC 23 | Modulation left/right relative phase (ALT-RATE). Bipolar — 12:00 is in phase. At 7:00 and 5:00 the LFO waveforms are inverted relative to each other; at roughly 9:30 and 2:30 they are 90 degrees out of phase (quadrature), which creates a wash or tumbling effect. At any setting besides 12:00 the random waveforms are independent per channel. |
| MOD DEPTH L/R | CC 25 | Modulation depth left/right balance (ALT-DEPTH). Bipolar — 12:00 modulates both channels equally. Turning left decreases modulation on the right channel and vice versa, with the maximum set by DEPTH. |

Special MIDI Functions
- Tap Tempo — CC 89
- Expression — CC 4
- Receive MIDI Clock — CC 110. Global setting — when on, the pedal synchronizes delay time and modulation to incoming MIDI timing clock. On by default.
- Independent L/R Shift — CC 114. Off (default) links the two channels, so SHIFT sets both and ALT-SHIFT tilts between them. On makes the shifts independent: SHIFT sets the left delay shift amount and ALT-SHIFT sets the right.
- Feedback Invert — CC 119. Inverts the phase of the delay feedback, changing the character of resonant flanging sounds. Only noticeable with short delay times. Saved in presets but not remembered when the pedal is turned off.
- Feedback L/R Tilt — CC 21. Feedback left/right balance — editor/MIDI only. Bipolar: at 50% (64) both delay lines use the FDBK setting. Below 50% the left feedback stays and the right is reduced; above 50% the right stays and the left is reduced. Minimum and maximum disable feedback for the right and left delay respectively.
- Delay Note Division — CC 108. Tempo-synced delay division, 0 = off (tap tempo disabled) through 31 = 128th note. Range: 1/128th note to whole note. Only takes effect with tap tempo or MIDI clock running.
- Modulation Note Division — CC 109. Tempo-synced modulation division, 0 = off through 31 = 128th note. Range: 1/32nd triplet to 8 measures. Only takes effect with tap tempo or MIDI clock running.
- Trails Mode — CC 111. Preset trails setting: 0 = off (echoes stop immediately when the effect is turned off), 1 = on (echoes decay naturally), 2 = use the global setting (default).
- Left Footswitch Mode — CC 112. SHIFT footswitch behaviour: 0 = shift momentary (shift is on while held), 1 = shift latching, 2 = tap tempo. Remembered when the pedal is turned off but not saved in presets.
- Right Footswitch Mode — CC 113. ON footswitch behaviour: 0 = momentary, 1 = latch, 2 = mute output in bypass (trails are disabled). Remembered when the pedal is turned off but not saved in presets.
- SHIFT/TAP Footswitch Press — CC 80. Emulates a press of the SHIFT/TAP footswitch (0-63 release, 64-127 press). The hardware expects gated behaviour — 127 on press and 0 on release — so this fires the press only.
- ON Footswitch Press — CC 81. Emulates a press of the ON footswitch (0-63 release, 64-127 press). The hardware expects gated behaviour — 127 on press and 0 on release — so this fires the press only.
Hardware Presets
Raster 2 has 4 hardware preset slots, recalled using MIDI Program Change. Saving requires an action on the pedal; follow the hardware preset manager instructions.
