What is Different

Before

Scattered source updates, isolated context, and manual follow-up across multiple feeds.

Now

Introduces a single livecoding environment where music code, playback control, and visual feedback (piano-roll + waveform) are integrated in one interface.

Why Track This

Why It Matters

Musicians and audio educators can run music-creation workflows directly from code while seeing notes and waveform context in the same screen, which can shorten composition iteration; however, iOS Safari users currently reporting no audio at startup may be blocked from using the tool on that platform until this is fixed. The current signal is strongest around usability of an integrated livecoding workflow, so operators and early users should watch mobile audio initialization, browser autoplay/startup behavior, and whether the Whop-hosted packaging adds friction or limits standalone use.
