What’s new

Icoustic 1.0 on iPad, Mac, and iPhone:

• One library — point each device at its own folders of MP3, FLAC, and M4A. Music from every shared device appears together in Songs and Albums (copies on two machines appear twice). Artists and Genres stay off until you enable them.
• Play from any device to any device — open Icoustic on the same Wi‑Fi and every Mac, iPad, and iPhone appears in the sidebar. Pick a destination from a device row or the play-bar Playing on… chip; drag tracks onto a row to queue them there. Local playback keeps going when you switch destinations.
• Pins — pin a playlist from a shared library and its tracks are on this device, so it plays with the source off. A pin freezes membership at pin time.
• MCP — on Mac, connect Claude, Cursor, or ChatGPT Desktop to the local library. It proposes; you review every change in MCP Actions.
• Spaces removed — devices on the same network approve each other. No codes, no accounts, no QR. Sharing is per folder. Rejected devices sit under Settings → Connect.
• Files as truth — tag edits and ratings write back via TagLib; play counts live in the owning library’s index (50% of the track or 4 minutes, whichever comes first). Peers send ratings, plays, and tag edits over the LAN.
