30+ available Instruments
Threads is a three-layer acoustic sequencer built for rhythmic pattern generation with organic sources. Each layer operates independently with its own step count, tempo division, playhead order, and note distribution—letting you create polyrhythmic patterns that drift, lock, or reorient against each other. Velocity is shaped directly within each lane by clicking and dragging, adding human-like nuance to even minimal sequences. Shift controls let you slide patterns forward or backward for syncopation, while humanize and gate length parameters keep things loose or tight depending on what you're after. Whether you're working with studio strings, Balinese gamelan, metallophones, or percussion, Threads turns acoustic recordings into rhythmic ecosystems that feel composed but never static.
Engine features

The central blend macro lets you stack layers progressively, building from simple sequences to complex rhythmic textures in real time. Divisi mode splits incoming notes across the three layers for even more variation.

Layer-specific FX sends, envelope controls, and varispeed tuning give you detailed control over each voice, while global processors—delay, reverb, EQ, distortion, compression—shape the overall sound.
