Old Blood Noise Endeavors IOTA Tone Generator Pedal In Zenith Silver

The Old Blood Noise Endeavors IOTA is a standalone sequenced tone generator that turns your pedalboard into a compact synth workstation. Sitting somewhere between arpeggiator, drone machine and experimental groovebox, it creates evolving melodies, pulsing textures and cinematic soundscapes without needing a guitar plugged in. In Zenith Silver, it is a striking centrepiece for ambient artists, producers and sound designers who want deep sequencing power in a familiar pedal format.

At its core, IOTA combines a flexible oscillator, white noise generator and programmable sequencer, all wrapped in intuitive hands-on controls. Twelve illuminated note buttons let you define scales and patterns on the fly, while Rate, Direction, Range and subdivision options dictate how your sequence moves through up to five octaves. From slow, drifting drones to hyperactive chiptune flurries, you can sculpt detailed, tempo-synced lines that lock to your set or wander into controlled chaos.

Beyond its core sound engine, IOTA is built for performance. Glide, Bend, Swing and Hold controls invite expressive, human-feeling phrases, while the envelope section shapes each note from percussive blips to swelling pads. Onboard presets, extensive MIDI control, expression pedal support and an assignable auxiliary footswitch mean you can integrate IOTA into complex live rigs or studio setups with ease, recalling full sequences and sound designs at a tap.

Designed by Andy Othling and handmade in Oklahoma, IOTA reflects Old Blood Noise Endeavors commitment to creative, left-field tools. Whether you are building ambient beds, adding sequenced hooks to a band mix, or exploring generative patterns in the studio, this compact box offers a deep, inspiring playground for anyone who loves experimental sound.

Programmable Sequencer at Your Feet

IOTA lets you build sequences of between five and sixty notes using a twelve-button note bank, with root note and scale interval selection for musical, harmonically coherent patterns. With a five-octave range, multiple directions and seven tempo subdivisions, it can handle everything from simple arpeggios to sprawling, evolving lines that underpin entire tracks.

Versatile Oscillator and Noise Engine

The oscillator moves smoothly between sine, harmonic and bit-crushed waveforms, covering warm, rounded tones, rich harmonics and edgy, chiptune-inspired textures. A dedicated Noise control blends in white noise that tracks each note, adding airy shimmer, percussive attack or lo-fi grit to your sequences.

Expressive Performance Controls

Glide and Bend parameters introduce portamento and pitch modulation, while Hold and Swing shape rhythmic feel from straight, clockwork pulses to loping, syncopated grooves. The envelope section, with Mix, Length and Shape controls, lets you tailor each note from sharp stabs to long, evolving swells, making IOTA feel more like a playable instrument than a static pattern generator.

Deep Integration with Presets and MIDI

Twelve onboard presets and up to 127 MIDI presets allow you to store complete sound and sequence setups for instant recall. MIDI clock, note and CC support, plus an expression input and assignable auxiliary footswitch, make it easy to sync with external gear, automate parameters and control multiple aspects of the pedal at once, whether you are on stage or in the studio.

• Standalone Sequenced Tone Generator - Operates as its own instrument, generating synthesised notes, arpeggios and drones without requiring a guitar or other audio input, ideal for ambient sets, modular-style rigs and experimental performance.
• Flexible Oscillator and Noise Blend - Switchable sine, harmonic and bit-crushed waveforms plus a pitch-tracking white noise generator give you everything from smooth pads to gritty, lo-fi textures, all controllable from the front panel.
• Advanced Sequencing and Randomisation - Five to sixty note sequences across five octaves, with adjustable direction, subdivisions, skip patterns, random skip probability and a Scramble function, provide endless melodic and rhythmic variation at the touch of a button.
• Preset, MIDI and Expression Control - Twelve onboard presets, extensive MIDI functionality, expression pedal assignments and an auxiliary footswitch input allow deep integration into complex rigs and fast recall of detailed sound designs.
