Old Blood Noise Endeavors IOTA Tone Generator Pedal In Groovy Blue

The Old Blood Noise Endeavors IOTA is a standalone sequenced tone generator that turns rhythm and pitch into a playable instrument in its own right. No guitar or external sound source required: just tap in notes, set your tempo and let IOTA spin everything from hypnotic arpeggios and evolving drones to glitchy, chiptune-inspired patterns. Finished in Groovy Blue, it is a compact performance synth, sequencer and sound design tool that drops straight onto your pedalboard.

At its core, IOTA combines a flexible oscillator, a programmable note sequencer and a powerful envelope section, all wrapped in hands-on controls and deep MIDI integration. Twelve illuminated buttons let you pick notes, scales and presets directly from the top panel, while Rate, Direction, Range and subdivision controls shape how your sequence moves through up to five octaves. With stereo outputs, expression control and soft-touch footswitches that can be latched or used momentarily, it is equally at home on stage, in the studio or on your desk as a compact synth brain.

Standalone Sequenced Tone Generator

IOTA generates its own sound, so you can build complete melodic patterns, drones and rhythmic hooks without plugging in a guitar. The internal oscillator and white noise generator track every programmed note, letting you treat the pedal as a self-contained synth voice for live sets, looping rigs, modular-style jams or ambient soundscapes.

Hands-On Note and Rhythm Control

The twelve-button note bank makes it easy to choose a root note and build scales or custom patterns directly on the pedal. With a five-octave range and sequence lengths from five to sixty steps, you can create anything from short, repeating motifs to long, evolving passages. Adjustable Direction, Range and seven tempo subdivisions give you precise control over how your sequences move and groove.

Expressive Movement and Modulation

Glide and Bend parameters introduce portamento-style slides and pitch modulation, while Hold and Swing controls add repeated notes and off-kilter rhythms. Sixteen skip patterns and adjustable random skip probability bring controlled unpredictability, and the Scramble function instantly reshuffles your chosen notes for fresh melodic ideas at the touch of a button.

Deep Sound Shaping and Preset Power

The oscillator moves from smooth sine waves to harmonically rich and bit-crushed textures, with a dedicated Noise control to blend in white noise that follows each note. The envelope section offers Mix, Length and Shape controls, with envelope time tied to the sequencer rate for tight, musical responses. Twelve onboard presets, plus up to 127 via MIDI, mean you can store complete sounds and sequences, with expression assignments and global overrides tailoring IOTA to your exact workflow.

• Standalone Sequenced Synth Voice - IOTA creates its own synthesised notes, arpeggios and drones without needing any input signal, giving you a compact, self-contained instrument for ambient beds, rhythmic hooks and experimental textures.
• Flexible Oscillator and Noise Engine - Switch between sine, harmonic and bit-crushed oscillator tones and blend in white noise that tracks each note, allowing you to move from pure, glassy lines to gritty, chiptune-style sequences and percussive noise bursts.
• Powerful Sequencer with Creative Randomisation - A five-octave range, up to sixty steps, multiple directions, seven tempo subdivisions, sixteen skip patterns and random skip probability give you huge control over pitch and rhythm, while the Scramble function instantly generates new melodic variations.
• Performance-Ready Control, Presets and MIDI - Twelve onboard presets, MIDI access to up to 127 presets, expression pedal support, assignable auxiliary footswitch functions and soft-touch latching or momentary operation make IOTA a versatile centrepiece for live performance and studio setups.
