Noah Pred demonstrates how to create an entire electro track using just one photo—by mapping visual pixels to pitch, velocity, chance, and time via Photomat, Data Synth, and Data MIDI. It’s a deep exploration into image-based composition and reactive sound design.
Using a Single Photo to Build Rhythmic Bass, Chords, Pads, Leads, and Percussion
Host: Noah Pred (Manifest Audio)
Core Idea: Music created entirely from one image—excluding drums—using new Photomat, Data Synth, and Data MIDI tools added to the Sonification Bundle in Live 12.2
Mood: Industrial-electro with rainbow reflections, grainy noise, and lush harmonic structures
1 | From Photo to Sound: Theory & Tools
- Photomat lets you convert image pixel values into musical data—mapping brightness or color channels to pitch, velocity, chance, time, or rhythm
- The creative workflow emphasizes dynamic, high-contrast photos, rather than balanced imagery, to yield more sculpted sonic waveforms
- Limitations: images are sampled at a max of 48 pixels; Data Synth uses 256-pixel audio buffers
- Workflow reflects an intentional return to photography—capturing moments as emotional memory, then reinterpreting them through sound
2 | Building Bass from RGB Noise
- Noah starts with a single storm/rainbow image sample; dragged into Data Synth as a wavetable
- Maps pixel line forms directly into synth tone; adjusts contrast, saturation, and filter to shape bass timbre
- Moves to Photomat, set to image mode + 25% resolution: generates ~102 MIDI notes
- Sets sonification ranges so that lower pixel values produce higher velocity and higher pixel values produce lower velocity, giving the baseline a rhythmic depth
- Creates multiple variations by zooming in to different image segments, adjusting resolution or threshold ranges, and tweaking key mapping with F harmonic minor
3 | Percussive Noise Patterns via Luminance Slicing
- Uses Photomat (Y-axis + luminance) zoomed into specific visual rows to generate 16th-note percussion bursts
- Applies FM, noise, high-pass filter, pan modulation, and LFO smoothing for evolving rhythmic coloration
- Zoomed-in subtleties add grain and dynamic movement to repetitive parts
4 | Polyphonic Chord Pads from Image Color Channels
- In Photomat’s Note mode, sets resolution low (e.g. fewer notes per cycle) and enables polychord mode: red, green, and blue channels map to separate voices
- Uses ‘spread’ control to separate voices into harmonic space, producing shifting chord clusters from static pixel data
- Further variation controlled through contrast, saturation, position panning, and note length adjustments
5 | Data MIDI Leads and Envelope Control
- Employs Data MIDI for real-time pixel-to-MIDI conversion, controlled by pixel sample rate (e.g. every 2nd column)
- Adds poly mode to generate chordal output, plus envelope shaping and plot visualization to follow data playback
- Uses Data Mod (new modulation tool) to map image-based values to MIDI modulation paths—like filter cutoff—through slower rhythmic clocks, adding evolving timbral movement
6 | Wiring It All Up: A Prototype from One Image
From this single source image, Noah builds:
- Multiple baselines, sampled and refined individually
- Percussion generators with noise and chance control
- Evolving chord pads, polyphonic and spread across time
- Leads and modulations shaped by image structure and MIDI intelligence
All of it remains traceable back to the same rainbow photo—exploring the sonic design space embedded in a visual moment
