* fix(orbit): keep Catch Up button visible long enough to click Reported during testing: the Catch Up button "appears for a moment, then disappears too fast to click". The single-stage debounce only filtered the show direction (require ≥ 3 s sustained over-threshold before showing), but on a real-world high-latency session the genuine drift fluctuates between ~1 s and ~8 s in lockstep with both sides' chunked `currentTime` updates — so the button vanished as soon as drift dipped briefly under 3 s, even though the drift baseline was still 5–8 s. Add a hide-side hysteresis: once visible, the button stays visible until drift has been under a tighter 1 s threshold for ≥ 1 s. Otherwise the noisy 1–3 s drift valleys keep the button up so the user can actually click it. Constants left as locals; if testing wants different floors we can extract. * docs(changelog): add catch-up hysteresis bullet * fix(orbit): show Catch Up when host paused + serialise seek-then-pause Two follow-ons after the hysteresis change: **1. Show Catch Up even when the host is paused.** The visibility gate required `state.isPlaying === true`, but a guest who joined while the host was paused still benefits from Catch Up if their sync to the host's paused position failed (engine drop, brief network blip during initial-sync, manual local seek). Drop the `state.isPlaying` gate — the only signal that should matter is "drift between us and the host's reported state" — which `computeOrbitDriftMs` already computes correctly in the paused case (no time-extrapolation, just `guestPos - hostPos`). **2. Defer the play-state mirror after `player.seek`.** Reported symptom: "I press Catch Up, the player pauses; when I press play, it resumes from the *old* position and the waveform jumps back." Root cause: `player.seek` debounces `audio_seek` via `setTimeout(0)`, while `player.pause` / `player.resume` fire their invokes synchronously. Pause arrives at the engine first, leaving it paused at the pre-Catch-Up position with the seek queued behind. When resume happens later, the engine plays from the old spot. Push the play-state mirror behind a 200 ms `setTimeout` so the seek's invoke lands first.
A modern desktop client for self-hosted music libraries
Fast. Native. Beautiful. Built for people who actually care about their music collection.
Psysonic is built primarily for Navidrome and also works with Gonic, Airsonic, LMS and other Subsonic-compatible servers, depending on the features supported by your server.
No telemetry • Native performance • Navidrome-first • Community driven
Warning
Psysonic is under active development. Bugs and rough edges can happen, and features may change as the project evolves.
What is Psysonic?
Psysonic is a desktop music client for self-hosted music libraries. It is designed for people who want the freedom of their own server without giving up the comfort, polish and speed of a modern music app.
It is built with Rust, Tauri v2 and React, with a strong focus on responsiveness, customization, practical music-library workflows and a user interface that does not require a manual before you can press play.
Psysonic is optimized first and foremost for Navidrome. Other Subsonic-compatible servers can work well too, but advanced features may depend on server-side support.
