0.1.571 Beta

Highlights

• Expression graphs: node graphs that compute expression curves from other curves, notes and LFOs. Each renderer gets a default graph, and a track can choose a different one. You edit them in the new Graphs tab of the Expressions window, and can share them as .ougraph files. by @stakira, with more node types by @Astel123457 in #2477
• Built-in hifisampler: a C# port of hifisampler, built in, with breathiness, voicing, tension, gender and growl controlled by curves. It needs the pc_nsf_hifigan_44.1k_hop512_128bin_2025.02 and hnsep_240512 packages. by @stakira
• Worldline-R1.1: Worldline-R with hnsep features and continuous noise. It needs the hnsep_240512 package. by @stakira
• Track Effects UI: a live EQ, compressor and reverb rack. You hear changes during playback, and the window doesn't block the editor. by @stakira
• DAW integration: a DAW integration API connected to the UI, with an in-app bridge guide that detects the install and can install with one click. by @KakaruHayate in #2369, #2376, #2476
• Singer selector: the track header's singer menu is replaced by a new singer selector with search, so you can find a singer quickly in a large collection. by @stakira in #2444, #2450

New features

• Masked curves: curves that only have values where you draw them. There are two built-in ones: RPIT, filled with DiffSinger's rendered pitch by Load rendered pitch, and PITO, an absolute pitch override that graphs can use instead of PITD. by @stakira
• The built-in resamplers' voice effects can be driven by curves: BREC, VOIC, TENC, GENC, and the new GRWC (growl, hifisampler only). In hifisampler and Worldline-R1.1, tension now changes the glottal source shape (LF Rd). by @stakira
• Hifisampler and Worldline-R1.1 cache hnsep results as <stem>_hnsep next to the wav. The format matches hifisampler's, so the two can share caches. by @stakira
• Worldline resampler expression support. by @rokujyushi in #2437
• Native Linux and macOS wavtools are now supported. by @atouu in #1618
• Metronome. by @rokujyushi in #2341
• You can edit character.yaml and dsconfig.yaml in the Singers dialog, with validation, hover help and suggestions. by @stakira in #2456
• Curve shift and stretch tools in the piano roll. by @rokujyushi in #2393

• The part inside the piano roll's visible range is highlighted. by @maiko3tattun in #2416
• Phoneme bars like DiffSinger's are now shown for every renderer that ignores envelopes. by @rokujyushi in #2441

• The default phonemizer menu item is renamed "Select Phonemizer". by @maiko3tattun in #2151

Performance
