Blozzum is a studio for sound-reactive visual art. Build a composition from shapes, effects, and color, bind anything to your music, and watch it move, bloom, and breathe in time with every beat — on the big, beautiful canvas of your iPad.
Whether you're improvising live, projecting at an event, or just losing yourself in hypnotic patterns, Blozzum gives you deep control with an instrument-like, hands-on feel.

Whether you're improvising live, projecting at an event, or just losing yourself in hypnotic patterns, Blozzum gives you deep control with an synth-like, hands-on feel.
HOW IT WORKS
Start from a shape. Add stacks of mutation and effects to twist, warp, and stylize it. Blend layers together, apply a chain of post effects, and finish with a final stage of touch ups. Then make it listen: different audio metrics (RMS, Frame Peak, Kick, Beat, etc.) can drive most any parameter in the paths, mutations, and effects — you decide what reacts to what. Use the mic for live input, or load an audio file and loop through it.
FEATURES
• Audio-reactive everything — drive motion, color, and shape with live mic input or your own audio files
• Multi-layer compositing — combine slots with blend modes for rich, evolving visuals
• Full effects pipeline — per-slot FX chains plus a final FX chain across the whole composition
• A library of generative shapes — daisies, spirals, lissajous curves, maurer roses, and more
• Final Render grade — rotation, spin, scale, position, brightness, saturation, contrast, and hue
• Signals and triggers — map RMS, peak, beat, and kick to anything, and build your own triggers
• MIDI control — bind your hardware to parameters and play Blozzum like an instrument
• External display — mirror your canvas to a TV or projector for performances and installations
• Save snapshots, start from hand-tuned factory presets, and crossfade between them in time
• Export your visuals as video to share anywhere
