Triangles by DETUNE
Music
$9.99 · Designed for iPad. Not verified for macOS.
Traditional DAWs bind sound to a single, rigid timeline. Triangles sets it free. Instead of placing notes in time, you place them in space. Every bounce is a note, every triangle a possibility — your geometric universe, playing forever.
Triangles is a creative sound toy where you place triangles on a canvas and launch balls that bounce off them, generating sounds as they collide. Arrange, customize, and compose — like painting with sound.
Features
- Place and arrange triangles freely on a vast field
- Balls bounce off triangles and generate sounds
- Spatial stereo panning — sounds from the right side of the canvas come from the right
- Off-screen sounds are still audible, with deeper reverb as distance increases
- Deepening reverb and filtering as you zoom out
- Reverb mix and room size are fully adjustable
- Multiple ball types with different sounds
- Import up to 8 of your own WAV sounds
- Scale and key selection for musical harmony
- Randomize notes, triangles, and balls instantly
- Build music intuitively with copy and paste — like drawing with sound
- Freely customize the colors of triangles, balls, and background
- Save and load your creations
- Relaxing and meditative experience for all ages
