Separation is useful when the result stays in the creative flow.
Loading and separation run away from the audio callback. Apple Metal acceleration and bounded FLAC caches support repeat analysis. Independent gain, mute, solo, seek, and export controls keep the results useful; isolated piano and synth parts can become MIDI with uncertain notes shown separately.
