## What is Triangles by DETUNE?

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

### 5/5 — 一期一会三角音曼荼羅

*2026-05-16*

インターフェイスが可愛いくて、wavを使うと好きな音色が使えます。

wavのファイルはKORGgadgetで音色を作り、audio shareでワンショットの音にしています。

ボールが当たるタイミングや周期をコントロールするのはなかなか難しく、むしろ水琴窟のような不規則性が心地良いかもしれません。

ボール同士がぶつかったり、隙間をすり抜けたり、段々ズレて行くのがまた楽しい。

音楽という概念を拡張するアート的作品で、画像をプロジェクターで映し出しながらライブ的に操作しても面白そうです。

作業中他のアプリを開いたりして戻ると音がしなくなる事があります。

バグも有りますが、

それもまた一期一会という味わいとして。
