SPECTRA
Open a recording. Reach the parts inside it.
SPECTRA separates a song into seven aligned stems, opens drums into six more components, and keeps the result playable, mixable, cacheable, and ready for FORMA.
Stem separator + performance mixerVersion 0.6.1macOS · Apple Silicon · VST3
Separation is useful when the result stays in the creative flow.
Analysis runs away from the audio callback, uses Apple Metal when it helps, and stores bounded high-resolution FLAC caches so repeated work is fast. Every stem keeps independent gain, mute, solo, save, and export control.

Six drum components
Open drums into kick, snare, hi-hat, cymbals, toms, and percussion with hierarchical mixing.
Fast repeat analysis
Metal acceleration and a bounded FLAC cache reduce waiting without touching the realtime audio thread.
