It is a tone generator with three wavetables, a five-octave sequencer and full MIDI control, built to put a synth on a guitar pedalboard. - Author: unknowndivide staff - Tags: Gear Old Blood Noise Endeavors, the Oklahoma City pedal company usually shortened to OBNE, released Iota today, and it is not an effects pedal at all. The company calls the [Old Blood Noise Endeavors Iota](https://www.oldbloodnoise.com/iota?ref=unknowndivide.com) "a tone generator, which is to say, a synth for your pedalboard." It makes its own sound from scratch, then runs that sound through a built-in sequencer, so a guitarist can drop a pulsing arpeggio or a slow drone into a signal chain without plugging in a keyboard. It arrived alongside a second version of the company's Float pedal, and both went on sale the same day with walkthrough videos on the official channel. ## Old Blood Noise Iota walkthrough Official walkthrough from [Old Blood Noise Endeavors](https://www.youtube.com/watch?v=%5Fo-eH1S%5FRv8&ref=unknowndivide.com) ## How the Iota tone generator works The heart of the pedal is a row of twelve light-up buttons. A single button labeled Root/Scale/Preset decides what they do. In Root mode one button picks the note the sequence is built around. In Scale mode any number of them can be lit, and each one adds an interval above that root, one semitone at a time, which is how you build chord-shaped arpeggios. In Preset mode the same twelve buttons recall twelve saved sounds. The sound itself starts with the Osc knob, which blends between three wavetables, a stored set of waveforms the oscillator reads from. At noon it is a slightly gritty sine wave. Turn it down and a richer, mid-focused wave comes in; turn it up and you get what the [official manual](https://www.oldbloodnoise.com/s/IOTA-Instruction-Manual-compressed.pdf?ref=unknowndivide.com) calls a chiptune sounding wave, the bright buzz of old video game consoles. A Noise knob blends in white noise that still follows the note being played, and an envelope section (Mix, Length and Shape) decides how each note swells and fades, from soft pulses to hard square chops. ## The sequencer: Range, Skip, Hold and Scramble This is where Iota gets strange in a good way. The pedal copies your chosen scale across five octaves, which gives it a list of anywhere from five to sixty notes. Range sets how much of that list gets played, from a single note up to all five octaves. Direction runs the sequence up, down or back and forth. Scramble shuffles the note order at random and holds that shuffle until you switch it off. Skip and Hold add controlled chaos. Above noon, both follow one of sixteen fixed patterns; below noon, they become a random chance. Skip drops notes out of the sequence, and Hold repeats the last note instead of moving on. Swing pushes every other note behind the beat, Glide slides the pitch from one note to the next, and Bend adds a small vibrato of up to one semitone, timed to the sequencer rate. ## MIDI, expression and stereo Every knob on Iota can be assigned to an expression pedal, and everything can be controlled over MIDI (Musical Instrument Digital Interface, the standard that lets gear talk to each other). Tempo locks to MIDI clock, and incoming MIDI notes set the root, so Iota can follow a drum machine or a digital audio workstation (DAW) instead of running free. Output is mono or stereo. The Aux footswitch triggers notes by hand, taps in a tempo or steps through presets, and holding it while turning Rate unlocks tempo subdivisions from a quarter of the speed up to four times as fast. It runs on a standard 9 volt direct current (DC) center-negative supply and needs 250 milliamps. The enclosure art is by Kilyn Massey, and it comes in three finishes: Zenith Silver, Vintage Yellow and Groovy Blue. ## Where to buy the Old Blood Noise Endeavors Iota Iota is available now from the [official Old Blood Noise Endeavors store](https://www.oldbloodnoise.com/pedals/p/iota?ref=unknowndivide.com), which also lists an Iota edition of the company's Expression Ramper controller and a bundle with the new [Float V2](https://www.oldbloodnoise.com/float-v2?ref=unknowndivide.com) that takes 15 percent off through November 10\.
