Meris Ottobit Jr — MIDI Editor & CC Reference

Control the Meris Ottobit Jr from your browser — full MIDI CC reference for 7 parameters, interactive editor, and AI-generated presets. Free, no install.

Nitelite gives the Ottobit Jr 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
SAMPLE RATE	CC 16	Changes the sample rate of the input signal from 48 Hz to 48 kHz. Lower sample rate settings create low-resolution audio with overtones similar to ring modulation.
FILTER	CC 17	Cutoff frequency of the Meris original ladder-style low pass filter, from 96Hz up to 24kHz. At max the filter is bypassed.
BITS	CC 18	Changes the bit depth from 1 bit to 24 bits, crushing the input signal and decreasing dynamic range.
STUTTER	CC 19	Sets the stutter play speed and length. The knob steps through 23 positions organized into Full Speed, Double Speed, and Half Speed ranges — each with 7 length selections from Stutter Once to Stutter Sixteen Times. Minimum position = Off. Maximum position = Random (combination of all above plus reverse).
SEQUENCER	CC 20	Sequencer play mode. CC ranges: 0-3 = Off; 4-32 = Play Once (1X); 33-59 = Play Twice (2X); 60-87 = Play 4 Times (4X); 88-115 = Play 8 Times (8X); 116-127 = Play Continuously (infinite).
SEQUENCER MULT	CC 21	Sets the sequencer speed as a multiple of the tap tempo. CC ranges: 0 = 1X; 1-19 = 2X; 20-39 = 4X; 40-59 = 8X; 60-79 = 16X; 80-99 = 32X; 100-119 = 64X; 120-127 = 128X. Higher multiples can push the Sequencer into the audio band for ring-mod-style effects.

Alt / Secondary Knob Functions

Control	MIDI CC	Description
STEP 1	CC 22	First step of the sequencer. Meaning depends on Sequencer Type (Pitch: semitone offset; Filter or Sample Rate: 0-100% modifier). CC 0 = skip, CC 127 = mute.
STEP 2	CC 23	Second step of the sequencer. Meaning depends on Sequencer Type (Pitch: semitone offset; Filter or Sample Rate: 0-100% modifier). CC 0 = skip, CC 127 = mute.
STEP 3	CC 24	Third step of the sequencer. Meaning depends on Sequencer Type (Pitch: semitone offset; Filter or Sample Rate: 0-100% modifier). CC 0 = skip, CC 127 = mute.
STEP 4	CC 25	Fourth step of the sequencer. Meaning depends on Sequencer Type (Pitch: semitone offset; Filter or Sample Rate: 0-100% modifier). CC 0 = skip, CC 127 = mute.
STEP 5	CC 26	Fifth step of the sequencer. Meaning depends on Sequencer Type (Pitch: semitone offset; Filter or Sample Rate: 0-100% modifier). CC 0 = skip, CC 127 = mute.
STEP 6	CC 27	Sixth step of the sequencer. Meaning depends on Sequencer Type (Pitch: semitone offset; Filter or Sample Rate: 0-100% modifier). CC 0 = skip, CC 127 = mute.

Footswitches

BYPASS — bypass on CC 14
TAP — bypass on CC 28

Special MIDI Functions

Tap Tempo — CC 28
Expression — CC 4
Bypass — CC 14. When on, the effect is bypassed (dry signal only). When off, the effect is engaged. Per Meris spec: 0–63 = FX bypass, 64–127 = FX enabled.
Stutter Hold — CC 31. Freezes the audio that is being stuttered. 0-63 = Hold Off; 64-127 = Hold On. When held before a stutter has trapped audio, the next played note/chord will be stuttered until released.
Tempo (7-bit) — CC 15. Sets the main timing directly as a 7-bit value (0-127). The tempo drives the Sequencer and Stutter and has a very wide range from 23.4 BPM to 6000 BPM (up to 768000 BPM effective when combined with Sequencer Mult).

Hardware Presets

The Ottobit Jr has 16 hardware preset slots. Nitelite can save your current settings to a slot and recall slots via MIDI program change.
